1st Edition

A P P L I C A T I O N

The TPU S420 has been designed as a protection and terminal unit for supervision and control of aerial and underground lines in radial electric networks with isolated, compensated, solid or limiting impedance neutral connection.

The TPU S420 performs a wide range of protection and automation functions. It has an extensive range of user programming options, offering high accuracy regulation in currents, voltages, temporisations and optional characteristics. All protection and automation functions settings are independent among themselves, having 4 groups of settings for each function.

There are 3 different versions of the TPU S420 which offer the user the flexibility to choose the suitable relay for each application. The possibility to program logical interlockings complementary to the existent control functions provides additional protection configuration that can be used to adapt the unit to the user’s needs.

The local interface of the TPU S420 integrates a graphic display where is presented a mimic with the state of all equipment of the bay, as well as its respective measurements. In the front panel there are also several functional keys that allow an easy operation of the protection in the most frequent operation situations.

As a terminal unit, the TPU S420 is capable of accurate measurements of all the values of a line and several fault monitoring functions, including Oscillograpy and Event Chronological Recorder. These functions allow its integration as a Remote Unit in EFACEC’s Supervision Command and Control Systems, offering at the same time a connection to a PC.

Together with the TPU S420 is supplied an integrated software package for PC interface with the protection – WinProt – either locally or through the local communication network. This application allows, besides other functionalities, the access and modification of relay settings and configurations and also the gathering and detailed analysis of the produced records.

High Set Overcurrent with high-speed tripping

The high set overcurrent protection is usually targeted for very fast protection where selective coordination is obtained through the setting of the RMS current (cut-off). In the TPU S420, high sets are independent for protection of phase to phase faults and of phase to earth faults. A selective timing can also be set.

Low Set Overcurrent with definite/inverse time

The low set overcurrent protection offers sensitivity and step timings for selective coordination (time-lag overcurrent). The TPU S420 provides both the independent and the inverse time options. These options comply with International Standards, which is a guarantee for compatibility with other devices. The functions of TPU S420 meet the IEC 60255-3 and IEEE 37.112 standards.

The settings of the low set overcurrent function are also independent for phase to phase and for phase to earth faults.

For the IEC complying option, the time-current functions follow the general expression:

Optional Dynamic Reset

The TPU S420 allows the dynamic reset option in the time-inverse operation of the low set overcurrent stage.

Even for the IEC inverse time functions, the TPU S420 offers the option of dynamic reset, thus allowing the partial replication of the cooling down of conductors subjected to short circuits.

The reset time follows the following expression:

[ ]12)/( −>

=IIAstreset

The TPU S420 is original in the extension of the dynamic reset as defined by the IEEE 37.112 to the time-current functions defined by the IEC 60255-3. So, the user has the option to account for the usually slow cooling down of the protected conductors after fault elimination.

It is worth mentioning that the accuracy of both the IEEE and IEC time-current characteristics is guaranteed for the full range of settings.

The implementation of both standards also follows the definition of the IEEE 37.112 standard, providing a defined behaviour for time-evolving faults. This behaviour also supports dynamic coordination between relays and fuses or reclosers located downstream the feeder.

Definite Time Universal Overcurrent with wide setting range

In parallel and independently from the previous functions, the TPU S420 performs a second overcurrent protection function with constant time.

The wide setting range of this protection function allows several applications:

To limit the operation time of the low set overcurrent protection in situations of low short circuit power where the operating times of this function can have important delays;

As a second high set protection stage, coordinated in time and current with other high set elements of protections downstream in the network;

As the main low set overcurrent protection with definite time, then the inverse time protection element becomes available to make a thermal replica of the conductors, particularly in the option extremely inverse with dynamic reset.

Option between virtual image of the zero sequence current and direct observation of the 4th current input

The TPU S420 is prepared to observe the zero sequence current of the line in its 4th current input, obtained either from the connection of the neutral point of the phase currents inputs, or from a toroidal current transformer in the line. However, the TPU S420 also performs internally the calculation of the zero sequence current in the line, directly from the virtual sum of the three phase currents.

For each of the three earth fault protection elements, the TPU S420 allows the selection of the source of the zero sequence current. This fact allows combining the observation of high phase to earth fault currents, using the wide operation range of phase CT, with the high sensitivity to high resistive faults given by the toroidal transformer. The sensitivity can even be increased by choosing a low nominal value for the fourth current input (0.2 or 0.04 A).

Directional Earth Fault Overcurrent Protection

In distribution networks with isolated or compensated neutral connection, the phase to earth fault currents can have very low values, similar to the unbalance currents circulating in the neutral connection.

It is possible to distinguish fault currents from unbalance currents by measuring the zero sequence active power in resonant systems and the reactive power in isolated systems. The measure of these power values is equivalent to the ratio between the phase fault current and the zero sequence voltage.

This is used in the directional function and it is also applicable in neutral systems with limiting impedance, as long as that impedance has a minimum resistive component.

The directional protection works independently from the overcurrent protection. Its role is to lock tripping when the fault is not in the line.

The maximum sensitivity angle of operation is selectable between -90º and 90º, being advisable a value of 0º for resonant neutral systems and 90º for isolated neutral systems. In systems with limiting impedance is advisable a 0º angle or superior, according to the resistive component of the impedance.

It is also possible to choose the direction in which the protection is intended to operate and its operation in case of polarising voltage absence.

The locking by the directional function can be independently attributed to each one of the earth fault overcurrent stages.

Directional Phase Fault Overcurrent Protection

The TPU S420 also features a directional phase fault overcurrent protection, which runs independently from the directional earth fault overcurrent protection.

To determine the current direction in each phase it is used the composed voltage of the other two phases, which maximises the protection’s sensitivity. The direction of the fault current is obtained even when the voltage collapses (very close fault). To perform this function, the TPU S420 stores the pre-fault voltage for 2.5 seconds. After that time it is possible to select the directional function behaviour.

The maximum power angles are selectable in a range between 30º and 60º. It is also possible to choose, as for directional earth protection, the direction in which the protection is intended to operate.

The locking by the directional function can be independently attributed to each one of the phase fault overcurrent stages.

Resistive Earth Fault

This function is an earth fault overcurrent protection for aerial lines that allows a selective operation in the case of very resistive faults undetected by traditional overcurrent protections.

The selective operation in case of fault is assured by a current dependent delay, which considers that the zero sequence current in the faulty line is greater than the zero sequence current in each of the non-faulty lines. The main application of this function is in networks with limiting impedance in the neutral connection.

The correct use of resistive earth fault protection is achieved in the TPU S420 by observing the zero sequence current through a toroidal transformer, with a transformation ratio of 20, connected to the 4th current input, which should have a nominal value of 0.2 A. With these particular choices a sensitivity of 0.5 A in the line is obtained, and the operational times are given by:

Optionally, the zero sequence current may be observed in the fourth input if a Holmgreen connection of the phase currents is used. In that case, the TPU S420 allows an automatic calibration that compensates the errors in the zero sequence current measurements for the different values of load current, so that the sensitivity of the function is assured in the full range of operation.

For line reclosing after fault elimination it is possible to define a current set greater than the protection starting current.

Resistive Earth Fault Protection Characteristic

Undervoltage

The TPU S420 integrates the undervoltage protection function, which allows the implementation of a load shedding scheme of the substation feeders. This function uses the phase to phase voltages, which are not affected by the disturbances of the existing neutral system.

This protection can operate with any phase to phase voltage, as it is usual, or as an user’s option, considering the combination of the three phase voltages. This option aims to make the protection immune to false voltage faults resulting from the operation of the voltage transformer (VT) fuses.

If the VT is protected by a circuit breaker, the TPU S420 performs additional security supervision when voltage collapses: the absence of current. If there is current in the feeder, the TPU S420 considers invalid the voltage collapse information from the VT.

The undervoltage protection has two independent time stages.

Overvoltage

The TPU S420 also integrates the overvoltage protection function. As the undervoltage protection, it uses the phase to phase voltages. The operation is always independent for each of the phase to phase voltages.

The overvoltage protection has also two independent configurable time stages.

Zero Sequence Overvoltage

In networks where there is not a solid neutral to earth connection, in particular in isolated or resonant neutral systems, a fault involving the earth causes a large unbalance in the non-faulty phase voltages which causes the appearance of a significant value of zero sequence overvoltage. That value can reach the phase to earth voltage value in case of very close faults.

Thus, as an additional protection against phase to earth faults in the mentioned neutral systems, the TPU S420 offers one zero sequence overvoltage element.

This protection is configurable in two independent time stages, coordinated with the zero sequence overcurrent protection. The pick-up voltage is set to three times the nominal value of the phase to earth voltage.

Underfrequency

The TPU S420 performs the underfrequency protection. Having operation times in the order of 70 ms and very accurate measurement, this function allows very fast frequency load sheddings.

Two underfrequency stages are available in the TPU S420, with independent settings. As an option, one of these two stages implements a virtual relay of negative frequency variation rate, allowing the anticipation of trips when this rate indicates serious disturbances.

Overfrequency

The TPU S420 also integrates the overfrequency protection function.

This function also has two time stages, independently configured, one of them operating on positive frequency variation rate.

The combination of under and overfrequency protections provides efficient protection against situations of isolated network supplied by small power producers.

Phase Balance

The phase balance protection aims at the detection of high values of the negative sequence current component of the three-phase system. The main application of this function is as unbalance protection that can be used in several situations.

The detection of broken conductors with or without earth contact, as well as the detection of phase absence are the goals of this protection due to the resulting negative sequence significant component.

The phase balance protection can also be used to eliminate two-phase faults, having in these cases a high sensitivity resulting from the difference of the negative sequence component in normal load and unbalance situations.

The TPU S420 has three independent stages of phase balance protection. The first one is of definite time with fast operation but less sensitive. The second stage is targeted at a more sensitive time protection. The timer can be of definite or inverse time, supporting the same standards as the other overcurrent protections.

The third stage operates according to the ratio between negative and positive sequence magnitudes. If the negative sequence value corresponding to this ratio is inferior to 10% of the nominal value, the protection works as a simple overcurrent stage.


Overload

The purpose of overload protection is to protect the equipment against thermal efforts of electric origin.

This function is based on the calculation of the thermal model through the observation of the phase currents circulating in the equipment. The operating characteristics take into account the equipment cooling time constant and the losses produced by Joule effect. The effect of the pre-overload currents is also considered in the calculations. The implementation of the function follows the IEC 60255-8 standard. The trip time associated with a current I and with a pre-overload current Ip is given by:

Additionally, an alarm level configured to a lower value of conductors’ temperature is available in the TPU S420. This alarm can be used to generate a signal before the function operation. The reset level is also configurable by the user.

As an alternative, the maximum or average value of the calculated thermal image can be used for each one of the phases.

Second Low Set Overcurrent with definite/inverse time

The S version of the TPU S420 offers, in addition to the three overcurrent stages mentioned before, a fourth low set stage, which can operate with definite or inverse time options. This stage complies with the same standards as the first low set stage. This function is offered both in the phase to phase protection and in the earth fault protection.

This fourth stage can be directional. The directionality settings are, however, dependent on the settings of the respective universal stage, being identical to those.

This way it is possible to have two independent sets of overcurrent protection, each with a high set and a low set: the first is composed by the high set and low set protections, the second composed by the universal stage, regulated as high set protection, and this additional fourth stage.

By setting opposite operation directions, the first set protects against the faults occurring downstream while the second protects against upstream faults.

Fourth Voltage Input

The TPU S420 provides a fourth voltage input beyond the three phase voltages. This additional input can be used in several cases, namely:

Logical interlockings derived from this voltage value.

Check of voltage presence in an auxiliary busbar.

As input in analogue comparators to perform undervoltage comparators.

As input ratio in analogue comparators to perform overvoltage comparators.

Fault locator

Complementing the protection functions, the fault locator gives very accurate information on the distance to the eliminated short circuits. The start signals of the functions of phase and of earth fault directional overcurrent protection are only used to define the fault loop or loops and the fault locator function operates independently of those functions.

The algorithm used compensates the load current in lines fed by two or more terminals. The fault loop and the distance – in Ω, km (or miles) and percentage of the line protected – are presented for the last ten detected faults.


C O N T R O L A N D A U T O M A T I O N

Automatic Reclosing

The TPU S420 executes the automatic reclosing automatism, allowing the execution of up to five reclosing cycles, completely configurable. The main purpose of this function is the service restoration of a line after the elimination of temporary or intermittent faults, common in aerial networks.

Reclosing sequence starts with the disconnection of the faulty line, followed by the reclosing command, after the dead time defined for the current cycle. According to the type of cycle configured, the opening command has different sources. In the fast cycle, the opening is done directly by the automatic reclosing automatism, while in the slow cycle the circuit breaker is opened by the protection functions.

After the closing command, the automatism waits a configurable time to confirm fault absence. If the fault is still present after the reclosing attempts, a definitive trip signal is generated.

Additionally, fast cycles allow a time delay in the tripping command in order to avoid reclosing caused by very fast disturbances which do not cause the tripping but only the start of the protection functions.

The logic conditions for automatic reclosing operation are configurable through the programmable logic of the TPU S420.

Load Restoration after Voltage Trip

Associated to the undervoltage protection, the TPU S420 can execute the load restoration automatism after voltage trip.

This function is performed in each of the substation feeder protections and consists in the disconnection by the undervoltage protection and posterior service restoration after a configurable time with stable voltage conditions.

To execute a sequential load restoration it is necessary to configure the time delay with stable voltage conditions on each protection present in the restoration cycle.

T = 10 s T = 15 s T = 20 s T = 25 s

Distributed Restoration

Load Restoration after Frequency Trip

In a similar way to the load restoration after voltage trip, the TPU S420 can execute simultaneously the load restoration after frequency trip with a programmable time delay with stable frequency conditions.

This function allows the definition of a logical condition to start the restoration cycle. This feature is fundamental when the restoration is integrated in a global load restoration plan that depends usually from information coming from the Supervision Command and Control System.

Centralised Load Restoration after Voltage Trip

Optionally, the TPU S420 can perform, according to a centralised philosophy, the load shedding and restoration after voltage trip. This automatism allows an integrated solution to the load shedding and restoration, when the feeder outputs don’t have voltage measurements accessible or when a more centralised management of such function is preferred.

Its operation is based on the execution of load shedding and restoration in a specific unit (TPU B420), located in the busbar, and in tight interaction with all feeder protections. The busbar protection is responsible for the complete control, giving load shedding and restoration commands to all feeder units. The TPU S420 simply executes the load shedding and restoration orders received from the management unit. The interaction can be done completely through the local area communication network.

Centralised Restoration

Centralised Load Restoration after Frequency Trip

As for the load restoration after voltage trip, the TPU S420 performs, optionally, a centralised load shedding and restoration after frequency trip.

The operation of this function is similar to the centralised load restoring after voltage trip.

Logical Trip Lock

The TPU S420 executes the logical trip lock control function. Its main purpose is to obtain a fast protection tripping, through the interaction with the downstream protections.

This function is based on the lock of instantaneous trips of the high set overcurrent protection after receiving a logical signal from the downstream protections. This signal results from fault detection by those protections and is transmitted through cabling or through the local communication network.

Thus, it is possible to obtain a high speed tripping if the downstream protections do not detect any fault. A small time delay is enough to ensure selective operation.

Circuit Breaker Failure Protection

The main purpose of this function is to verify the correct operation of a circuit breaker in case of fault. Its operation is based on the information produced by the overcurrent protection functions.


Thus, immediately after the execution of a circuit breaker trip command by any protection function, the breaker failure function starts. If the protection function does not reset after a configurable time (for example, due to circuit breaker damage), a command is generated to other equipment (for example the upstream circuit breaker). This information may be transmitted by dedicated cabling or through the local communication network.

Trip Circuit Supervision

The TPU S420 can permanently monitor the trip circuit of the circuit breaker through binary inputs configured for that purpose.

If there is some discontinuity when the circuit breaker is closed, the trip circuit supervision input resets and an alarm is generated after a configurable time.

Supervision scheme of the circuit breaker trip

Protection Trip Transfer

The TPU S420 executes the protection transfer function. Its operation consists in the monitoring of the bypass disconnector state, when existent, in order to operate the bus-coupler circuit breaker.

When the panel is transferred, some automatisms, such as the automatic reclosing are locked, and tripping commands of the protection functions are executed on the bus-coupler circuit breaker.

Circuit Breaker and Disconnector Supervision

The TPU S420 allows two distinct mechanisms to execute commands. Through the local interface, it is possible to select any device and to command it. Remotely, it is also possible to execute the same operation. However, such actions are conditioned to the interlockings related with the communication.

Each command received, either locally or remotely, is monitored and the success of the operation is signalled. The monitoring is based on the state variation observation of the binary inputs associated to each device. The operation supervision is available for circuit breakers and for disconnectors.

Programmable Logic

One of the main features of the TPU S420 is a completely programmable logical scheme which allows the implementation of timers, programmable delays or other logical combinations beyond the traditional logical functions (OR and AND). The TPU S420 has internally a set of modules formed by a variable number of logical gates. The user may change all internal connections within the module and/or interconnect the several modules. The user may also change the descriptions associated to each logical gate, the gate type, the timers, the initial gate state, etc.

This flexibility may be used to configure additional interlocking to the control functions or any other complex logical conditions.

Distributed Automation

The complete integration of the TPU S420 in Supervision Command and Control Systems allows the definition of control functions that take advantage of their connection to the local area network (LAN). This means that, besides the vertical communication with the control centre, fast communication mechanisms among the several control and protection units are available.

This feature gives the possibility to implement advanced automatisms, interlockings or other logical functions based on the interaction through the local communication network. This function is available in versions integrating the following communication protocols:

Lontalk Protocol

IEC 60870-5-104 Protocol

IEC 61850 Protocol

Operation Modes

The TPU S420 allows the specification of several operation modes, which affect the operation of the control and protection functions.

In the front panel there are two operation modes, configurable by the user. They are usually associated with the bay operation mode, specifically with the control and supervision functions performed by the relay. Current status of each mode is signalised by LEDs and may be directly changed through the associated functional keys.

Besides theses modes, the TPU S420 also includes a menu to access other operation modes that may be required.

The Local/Remote operation mode defines the relay behaviour concerning the received information from the Supervision Command and Control System. When in Local Mode all remote operations are inhibited.

The Manual/Automatic mode concerns the control functions executed by the TPU S420. When in Manual Mode all control functions are locked. This mode is fundamental to perform maintenance tasks, with the system in service.

The Normal/Emergency mode refers to the system’s special operation. When in Emergency mode all logical interlockings of circuit breaker commands are inhibited.

The Special Operation A and B modes are characterised by the instantaneous operation of the phase overcurrent protection and by the lock of the resistive earth protection and the closing commands generated by control functions.

In A mode the phase to earth overcurrent protection functions have instantaneous operation, while in B mode they are locked. Associated to each mode there are two logical inputs available for protection trip in case of external phase to earth faults.

Measurements

The TPU S420 accurately measures, in almost stationary state, the following values:

RMS value of the three phase currents and the zero sequence current (4th current input and virtual sum of the three phase currents);

RMS value of the inverse current;

RMS value of phase to earth and phase to phase voltages and zero sequence voltage, obtained by virtual sum of the three phase voltages and the 4th voltage input;

Frequency;

Active and reactive power and power factor;

Active and reactive energy counting (values stored in flash memory) supplied and received;

Temperatures.

Based on the measurements made, the TPU S420 calculates and registers, with date of occurrence, the following information:

Current peak (1 second average);

Active power peak (15 minute average);

Sum of the square current cut by the circuit breaker in each pole;

Number of circuit breaker manoeuvres.

The high precision obtained in the measurements generally avoids the use of additional transducers. All calculated measurements are available in the local interface or remotely through the connection to the local area network and to the Supervision Command and Control System.

Analogue Comparators

Additionally to all protection and measure functions, TPU S420 has a set of configurable comparators for analogue values, acquired and calculated in the protection.

The configuration of high and low levels, as well as the associated alarms provides the

implementation of comparison mechanisms which are useful for the operation of the energy system.

Load Diagram

The TPU S420 permanently calculates and registers the daily load diagram. This information is based on the calculation of the 15 minute average of each of the power measurements. All daily diagrams can be stored for a full month.

Each diagram may be accessed locally or through the software interface – WinProt. Data gathering is done through a serial port or through the LAN.

Oscillography

The TPU S420 registers and stores in flash memory a large number of oscillographies of currents and voltages (about 60 seconds).

The length of each oscillography, the pre-fault and post-fault times are variable and configurable by the user. By default, the recording starts 0.1 second before the protection start and ends 0.1 second after the reset of all virtual relays of the several functions. The maximum length is 1 second. The sampling frequency of the analogue values is 1000 Hz.

The close of the circuit breaker also triggers the recording of an oscillography, and it is possible to define other logical conditions to start this event. In particular, there are binary inputs which may be used for this purpose.

Unlike the load diagrams, oscillographies can not be visualised through the relay’s local interface. They must be visualised in a PC, using WinProt.

Event Recorder

The TPU S420 monitors the relay’s inputs and outputs, as well as all defined internal logical variables. Any state change or event is registered, with precise time tagging (1ms resolution).

Each event may be configured to be presented, or not, in the event recorder, according to the desired level of detail, as

well as the associated description and the records visualisation order. The TPU S420 stores several records in flash memory. The storage of a new record is done periodically or whenever there is a maximum number of 256 new events. Like the other records, the event record data can be accessed in the protection’s interface or visualised in a PC, using WinProt, with information gathered locally or remotely.

Event time-tagging

The event time-tagging done by the TPU S420 is always made in the local time zone of the country where it is installed. For this, it is necessary to set the deviation of the timezone relative to the reference given by the GMT time, as well as the day and hour of start and end of the daylight saving period, according to the legal regulations.

The TPU S420 receives periodically a time synchronisation signal through the local area network. In the absence of this signal, an internal real time clock allows the updating of the protection date and time when the protection is disconnected. Optionally, the TPU S420 can be synchronised through an IRIG-B signal, having a specific interface for that purpose, or trough a SNTP server, according to the RFC 2030 standard (in versions with Ethernet communications board).

System Information

The TPU S420 has available in real time a large set of system information. This information reflects the protection’s internal status, at both hardware and software level.

In terms of hardware it is possible to access the status of several electronic components, which are permanently monitored. The information associated to the software contains all the data regarding the relay identification, namely relay type, relay version, serial number, relay name, network address, etc.

All this information can be accessed locally or visualised in a PC, through WinProt. It may also be reported in real time to the Supervision Command and Control System through the communication network.

Binary Inputs and Outputs

The TPU S420’s main board has 9 binary inputs isolated among themselves and completely configurable. There is the option to use two expansion boards which can be of three types:

Board Type Inputs Outputs

Main Board 9 5+1

Type 1 Expansion 9 6

Type 2 Expansion 16 -

Type 3 Expansion - 15

On each binary input, digital filtering is applied to eliminate the bouncing effects of the power equipment. The logical variable and the configuration time are configured for each input, without loosing the right time-tagging of the start of each state transition.

The base version of the TPU S420 has 6 binary outputs, 5 of which are configurable. The sixth one is a changeover output which is activated by the internal watchdog in case of relay failure. The configuration is similar to the binary input configuration previously described.

In the type 1 expansion board there are two changeover outputs and in the type 3 expansion board there are six changeover outputs. These outputs aim to provide a solution for logical interlockings that require normally closed contacts, avoiding the use of auxiliary relays.

Serial Communication

The TPU S420 has available 3 serial ports for communication, two in the back panel and one in the front panel.

The two back panel serial ports can be used to communicate with WinProt. As an option, the back panel port COM1 can be used to support serial communication protocols, such as DNP 3.0 protocol, not requiring any extra communication board.

The front panel serial port is only used to communicate with the WinProt application.

For each back panel serial port are available four different types of interface, at the user’s choice, namely:

Isolated RS 232 Interface

Isolated RS 485 Interface

Glass optical fibre Interface

Plastic optical fibre Interface

SCADA Integration

The integration of the TPU S420 in SCADA systems can be done through serial communication protocols or through dedicated communication boards, namely:

Serial Interface supporting the DNP 3.0 protocol, with communication speeds up to 19200 baud.

Lonworks Board, using the LONTALK communication protocol, with a communication speed of 1.25 Mbps.

Redundant 100 Mbps Ethernet Board, supporting the IEC 60870-5-104 and IEC 61850 protocols. This board also provides the TCP/IP communication protocol for direct connection with WinProt.

Functional Keys

Through functional keys it is possible to change the operation mode of the protection, to select a specific device and command it, or to acknowledge an alarm.

Alarms

Next to the graphic display the TPU S420 has 8 configurable alarms. For each alarm it is possible to define an associated logical variable, choose the alarm type and the text presented in the display.

The TPU S420 has a graphic display where a variety of information can be presented, namely: mimic, parameterization menus and records menus. The mimic presents logical information with the equipment state, alarms description, analogue measurements and static information.

Security

Any user can access all information in the local interface. However, for security reasons, without the correct password the settings can not be accessed.


R E M O T E I N T E R F A C E – W I N P R O T 4

WinProt is a high-level software application designed to interface with EFACEC’s Protection and Control Units. It may communicate with different relays and with different versions of the same relay. Its architecture is based on the division of functionalities on specialised modules, whose access depends on the type of relay and the type of user.

The structured storage of all the information in a protected database is another fundamental feature of WinProt. Through the different modules it is possible to execute several operations described below.

Remote Access

WinProt allows local access by serial port through a modem and remote access through the local communication network (LAN) or even through an Ethernet network directly connected to the units. It is possible to configure the settings associated to each type of communication and each specific unit.

The use of a LAN has an advantage regarding the serial communication by allowing the access to any of the protections in the network without having to change physical configurations. Thus, any operation of maintenance, configuration or simply the system monitoring can be remotely done from the Supervision Command and Control System. It also can be done through intranet, if available.

Parameterisation Module

The parameterisation of each protection is done through a specific module – WinSettings – where is possible to configure function by function, to copy data from one relay to another, to compare settings from the database to those existing in the relay or simply to compare settings among different relays.

The user has a set of tools that help him do the parameterisation task, such as graphics with time-current characteristics, default settings, print configurations, comparisons list, etc.

Logic Configuration Module

WinLogic is a friendly tool to configure the relay’s programmable logic. This tool allows the implementation of any type of logical interlocking, including variable timers.

Besides the configuration of the connections between logical variables, the user can also define the text associated to

each logical variable, validate the changes made in the logical network, monitor in real time the full network status and make the logical simulation before downloading the configuration to the protection. Logical configuration complies with the IEC 61131-3 standard.


Records Analysis Module

WinProt has a specific module for visualisation, analysis and gathering of the records produced by the protection: WinReports.

The analysis of each record is simplified by the use of specifically designed graphical tools. For example, in the oscillography the user can zoom, see instantaneous values, see the phasors representation, displace the axis, etc. The load diagram and the event recorder can also be analysed.

Mimic Configuration Module

WinProt has a module for the mimic graphical parameterisation: WinMimic. This tool can only be used with units with a graphic display. It allows defining the symbolic part, the textual part and even the measurements and states to be presented in the protection mimic.

Together with this module it is available a library of graphical elements with which the user can build the unit’s mimic.

Unit Test Module

The objective of the unit test module, WinTest, is to execute automatic tests in the unit, without the need for external injection equipment such as test sets.

This module allows the simulation of analogue values injection, the generation of binary inputs state changes and the monitoring of outputs operation. It is also possible to monitor in real time every measurement and event produced by the relay.

Firmware Configuration Module

WinCode was designed as a WinProt module dedicated to the relay firmware download. This operation can be performed at any time but only by specialised technicians.


I N T E R F A C E W E B – W E B P R O T

All 420 family units offer an embedded web server, targeted to provide, visualize and change all the information stored in the unit. This server was conceived according to the most recent technologies, providing all data in XML format and providing JAVA tools (it implies the installation of a JAVA Virtual Machine). WebProt access is performed through an Ethernet local area network, by means of a standard HTML browser.

General Information

The main page presents all unit’s general data, namely, the order code, the application, the version and the serial number. From this page, it is possible to reach pages with more specialized data (parameters, registers, measures, etc.). There is also available an access counter, a map of the accessible pages in the server and a page with useful links (technical support, EFACEC Web site, e-mail, etc.).

Parameters

Through the WebProt, the user can visualize and change several functional parameters defined in the unit. Besides, this is subject to a previous password insertion, for changing purposes. It is also possible to print and export the complete data.

Records

WebProt allows the collection and analysis of the different records existing in the unit (oscillographies, event recording, load diagrams, etc.). Concerning more complex records, such as oscillographies, analysis tools are downloaded directly from the server, avoiding the need for high level specific applications.

Schematic Diagrams

Remote monitoring of the unit’s schematic diagram and alarm data is another feature, available in order to allow an easy and efficient access to the equipment state, as performed locally.
