GENERAL DESCRIPTION


PD300 User Manual 7

1. GENERAL DESCRIPTION The PD 300 family units are multifunctional protection relays of digital technology and they create the basic element used for the protection, measurement and control for 2 and 3 winding transformers and generator (see appendix). They can be used as autonomous elements for protection, control and measurement of an electrical bay or they can be integrated inside a Protection and Control Integrated System.

Inside this family there are different models, which only differ in some hardware points or in its functionality. The Firmware is common for all the models and the available functions are defined in a programmable logic circuit (PLD) The Firmware can be load in the unit through the serial port, which makes the version updating easier.

1.1 MANUAL SCOPE This manual does not correspond to a particular PD300 model, but it refers to the whole family. For each model, it will be only applied anything related to its physical characteristics and its functionalities. This manual is divided into two sections; the first one has the information related to configuration, functions and the second one has the appendixes: curves for timed function operation, communication protocols, and structure of the keyboard/display menus.

On the other hand, each unit is delivered with a summarized Characteristic Sheet in which the functions of that model are related to its connections diagram.

UNIT CONFIGURATION



3. UNIT CONFIGURATION The settings that are defined next configure the unit, so they are basic.

Some of them are only accessible by keyboard/display; some others are also accessible by Console

All of them are usually of single table (Table 0). By keyboard/display you access to the programming of the table 0 through the menu Settings (change) by means of the keys .

The differential protection generals are of 6 tables. By keyboard/display you access through the table programming.

3.1 PROGRAMMING OF DIGITAL AND LOGICAL INPUTS In this kind of units, two types of inputs vare considered: digital inputs (physical, wired in the fields) or logicals (internals). Each possible input function (for example breaker status)can only be programmed only either as digital or logical, but never both at the same time.

The digital input programming is as follows:

It is carried out through the console, in the Configuration of digital inputs screen, in the right upper chart.

By keyboard/display: PROG. TABLE 0 - PROG.CONFIG CONFIG. INPUTS

SELECC. N0/NC

INPUTS ACTIV. T.

CONFIG INPUTS allows programming a digital input among the following possibilities:

Breaker status (general and for each breaker)

Close command (general and for each breaker)

Open command (general and for each breaker)

External protection (general and for each breaker)

Close unblocking

Set table 1. If a pulse is received, it sets the settings table 1 as the active table






Set Local/Remote command

Close circuit supervision with 52 open (2 or 3 breakers depending on the model)

Close circuit supervision with 52 closed ( 2 or 3 breakers depending on the model)

Trip circuit supervision with 52 open( 2 or 3 breakers depending on the model)

Trip circuit supervision with 52 closed ( 2 or 3 breakers depending on the model)

Local reposition. It turns off the tripping LEDs and it is equal to recognition for Keyboard/display.

Output reposition. It deactivates the relays programmed as Memorized.

Relay locking. When activating it set the relay out of service, but when it is deactivate the relay state will be the corresponding to the setting In service.

Instantaneous inhibition. It locks the trips of the instantaneous overcurrent units, but it allows the pick up

Instantaneous inhibition winding 1, 2 or 3. It locks the trips of the instantaneous overcurrent units on the indicated winding, but it allows the pick up.

UNIT CONFIGURATION



Neutral inhibition 1 or 2. It locks the trips of the instantaneous overcurrent units on the indicated neutral, but it allows the pick up.

Free. The input may be used by the protection for lock out or logical, or it may not be used. In any case, its state may be transmitted to control.

It should not be programmed more than an input with a certain function.

SELECC. NO/NC. It defines if the input must be interpreted like active when it is viewed closed or when it is viewed open. Regardless it has been selected NO/NC, the digital inputs programmed in outputs, logics,leds, state signalling are seen at 1 when there is voltage in the input, and at 0 when there is no voltage in the input.

For example, for the status of the circuit breaker, if we use a contact 52a we should program the corresponding input as NO (when it closes it will indicate closed circuit breaker), while if we use a 52b we should program it as NC (when it opens it will indicate closed circuit breaker).

INPUT ACTIV. T. (time of activation of inputs). It is a software filter for the activation / deactivation of digital inputs. The HW filters is of 1 to 2 ms, and it can be extended by software in the number of programmed milliseconds (range 0 to 20 ms.

The programming of digital inputs is the following one:

It is carried out through the console, in the Configuration of digital inputs screen, in the right lower chart.

A logical input is a virtual input(not physical)the state of which depends on the corresponding digital signal( input 1 corresponds to logical signal 1, input 15, to signal 15. its function is the one programmed( the possibilities of programming are the same as the ones of the digital inputs).

This procedure allows the assignation of relay internal signals to those inputs as if they were wired field signals. Up to 15 logical inputs are allowed( because there are 15 logical signals).

NO/NC selection,active input when the logic is active or inactive.

Delay is not applied to the activation.

Example: if logical input 3 is programmed as breaker state and NO, the unit will consider that the breaker is closed, when logical sign is inactive.

A certain function must only be programmed as one input. It is not admissible, for example, to program state of the breaker as a digital input and as a logical input.

3.2 FLICKER TREATMENT IN THE DIGITAL INPUTS The flicker or bouncing consists of the quick and continuous change of a digital input, usually associated to a failure in the input contact. This function allows carrying out a control to disable the inputs or digital signals that blinks so as not to interfere in the system integrated in the control, because when a digital signal is disabled, it does not generate any state change.

This function has 3 settings:

Minimum number of changes to mark NFLICKER fault: Minimum number of changes of a signal that must occur in TFLICKER seconds (parameter) to consider that the contact is faulty and that this signal is disabled (the changes are not treated and its state is not refreshed). Value between 0 and 255. Value 0 inhibites the signal disabling treatment due to blinking.

Minimum number of changes to remove the QFLICKER default mark: Maximum number of changes of a signal that must occur in TFLICKER seconds (parameter) to consider that the contact is not faulty and that the signal previously disabled is enabled. Value between 0 and 255. Value 0 inhibites the signal automatic enabling treatment when theblinking disappears.

Default decision interval (TFLICKER): time nterval, in seconds, for the tretament of the disabling or enabling of the digital signals by blinking. Value between 1 and 60. If a digital input changes its state more than NFLICKER times in a time of TFLICKER seconds (parameter) this input is disabled. If the NFLICKER paramater has a value 0, the blinking control is not carried out.

Once a number of changes higher than the one programmed is detected, the signal is set as invalid, a Procome change is generated indicating the change into invalid and, from this moment on, changes in this signals are not detected.

UNIT CONFIGURATION



For the subsequent enabling of the disabled digital signals, there are three options:

Manual reset manual of the unit.

Automatic enabling: if a digital input previously disabled changes its state less than QFLICKER times in a time of TFLICKER seconds, this input is enabled. If the QFLICKER paramater has a value 0, the automatic enabling of the digital outputsl is not carried out.

Enabling by operators command :Default order or programmed by the user (generic order that can be sent from the console or telecommnad) through which the unit is indicated to enable all the digital inputs that were disabled. The order only provoques the enabling of the disabled digital inputs without having influence in the blinking treatment, that is, if, after the order, input blinking is detected, they get disabled again.

3.3 PROGRAMMING OF DIGITAL OUTPUTS By console it is carried out in the screen Digital outputs configuration.

By keyboard/display: PROG. TABLE 0 - PROG.CONFIG PROG. OUTPUTS

OUTPUT ACTIV. T.

The functionality of each digital output can be programmed like an OR of the logical signals available in this unit (see point List of available signals, in the appendixes.)

In the programming through Console (recommended), for each digital output it is clicked with the mouse in the cells corresponding to the signs whose OR wants to be activated by the output. (Matrix programming).

In the programming screen, at he end of the available signal list, there is a row with the title OTPUT TYPE, in which each output is defined as Trip, T1, T2 , T3, Close, C1, C2 , C3, Memorized or Nothing. The operation depending on the output type:

If it is of the type trip the output carries out the sealing logic( if the sealing setting is set to yes) and that of opening failure of 2 or 3 breakers (depending on the model).

If it is of the type T1, T2, T3 the output carries out the sealing logic (if the sealing setting is set to yes) and that of the open failure of the specified breaker.

If it is of the type Close the output carries out the sealing logic( if the sealing setting is set to yes) and that of opening failure of 2 or 3 breakers (depending on the model).

If it is of the type C1, C2 o C3 the output carries out the sealing logic (if the sealing setting is set to yes) and that of the open failure of the specified breaker.

If it is Memorized, once it has been activated, it can only be deactivated by a digital input programmed as output.

If it is set to nothing it does nothing special

The output activation time defines the minimum operation time of each physical output, once it has been activated (in seconds). The range is from 0.05 to5 seconds. It appears in the last row of the screen.

Through keyboard it is more difficult. In PROG OUTPUTS, we can find ASSIGN SIGNALS for each of them with the following possibilities:

NO SIGNAL (the output remains without assigning, but it can be activated by control commands)

SAME SIGNALS (it is not wished to change the current programming)

OTHER SIGNALS (it is wished to change the current programming). When pushing (Intro), it is gone through the logical signals with the arrow ; when we arrive to a signal that we want to use in the OR that defines the output, we press R; when we finish with the signals, we pulse , which takes us to the programming of the output type, with the possibilities already indicated.

UNIT CONFIGURATION



3.4 PROGRAMMING OF LEDS Through Console, it is carried out in the screen LEDs programming By keyboard/display: PROG. TABLE 0 - PROG.CONFIG PROG. LEDs

OUTPUT ACTIV. T. The proceedings are totally analogous to the programming of digital outputs, except that the activation time is not programmed and that the possible types are Memorized and Non memorized. The non-memorized turns off when the cause for turning on disappears; to turn off the memorized a Fault acknowledgement must be done either by keyboard/display or digital input.

3.5 PROGRAMMING OF LOGIC OUTPUTS The user can configure up to 15 logic outputs, called logic 1 to logic 15 and they can be assigned to output relays, LEDs, locked inputs, signals to be registered in the oscillograph data recorder , etc

The logic output programming can be only carried out through the protection Console, (and not through keyboard/display) from he available basic signals which are detailed in the Appendix Available signals (as many of them corresponds to optional functions, all the models do not have all these functions) The programming procedure is described in another document: Protection Console Manual

Logic signals are generated in accordance with the following layout:

As it can be seen, defining a logic output involves the following:

up to 16 of the available signals (or their negations), forming an OR function

up to 16 of the available signals (or their negations), forming an AND function

An OR or AND function is programmable from the results of the two foregoing functions.

A programmable delay for the activation of the output.

A programmable duration for the activation of the output

The delay is the time elapsed from the moment there is 1 logic at the output of the logic ports and the moment when the relevant logic output activates. If 1 disappears during that time, the signal does not activate. It can be programmed from 0 to 599.9 sec., in 0.1 sec. steps.

The pulse time (duration) is the time for which the logic signal remains active. It can be programmed in two ways:

"By logic": after the delay, the output remains active as long as there is a 1 at the output of the programmed logic.

"By time": the time is programmed for which the output must remain active, and after that time it de-activates regardless of the status of the programmed logic output. Only another move there from 0 to 1 will re-activate the output, once the delay has elapsed.

This time can range from 0.1 to 599.9 seconds, with 0.1 sec. steps. A logic output i can be used as available signal for another logic signal programming input j or for itself.

UNIT CONFIGURATION



Simple example of application: Digital output DO7 is to be made to follow digital input DI6 with a 1 second delay.

Delay time = 1 sec.

Duration = "by logic"

SD7 digital output programming: logic 1

3.6 PROGRAMMING GENERAL SETTINGS Relay on duty: it has to be set on YES for the protection to be completely operational. If it's set on NO the protection responds to communications and the keyboard/display so that it can enter into operation; it also activates the relay and/or LED which has been programmed as "Out of duty relay", deactivating all the rest.

Breaker number: this is an identification text. It may be programmed alphanumerically through communications, but only numerically through the keyboard.

Setting Minimum Maximum Step Notes Relay in service YES/NO Breaker number 5 alfanum. Characters

3.7 DIFFERENTIAL PROTECTION GENERAL SETTING PROGRAMMING It has 6 setting tables:

3.8 COMMUNICATION CONFIGURATION

3.8.1 Front door Communication (Port 1_1) and rear port no. 2 (Port 1_2) PD300 unit has its own address identifying number, which makes possible identify the messages sent to the unit from the PC through its front port ( or rear port) with protocol PROCOME. This address is programmable from the keyboard/display entering CHANGE SETTINS, "PROG. TABLE 0", "COMUNICAT.", FRONT PORT, UCL ADDRESS".

The units leave the factory with the address 4. This number is the one used in de Engineering program when defining the installation.

If for any reason this number is changed in Engineering, the address programming has to be changed and vice versa.

If a PD300 unit is replaced by another one, the installed unit must have the same address as the removed one.

The baud rate, parity and the number of STOP bits can also be programmed in the "COMUNICAT ". The units leave the factory at 19200 baud, even parity and 1 bit of Stop.

3.8.3 Ethernet Communication It is only applied in models with Ethernet port.

In order to configure the Ethernet port the fist parameter to be configured corresponds to the TCP/IP communication selection. It is programmed from the keyboard/display, by entering "SETTINGS (change)", "PROG. TABLE 0", "COMMUNICATIONS", SELECT COM TCPIP. The options of this parameter are: Procome and No. The operation according to this parameter is as follows:

Procome: Through Ethernet port communication with Procome protocol is possible. In this case the selection of Procome protocol in the other rear port (com 2) is not allowed. In short, through Ethernet port the communication is with Procome protocol, whilst in the second rear port (if available) communication is carried out through the selected protocol, except Procome.

NO. communication is not carried out through Ethernet port. In this case, the second rear port (if available) communicates through the selected protocol, Procome is allowed.

The remaining configuration parameters of Ethernet port are configured with the Sipcon console, in the menu Configuration TCP/IP). These parameters are those below:

Generals Protection IP address. It shows the protection IP address (server unit). They are 32 bits, in decimal notation separated

by dots.

Subnet mask. It defines which part of the IP address identified by the network. They are 32 bits, in decimal notation separated by dots. All those IP addresses that do not fulfil the net mask, that is, those which do not have the part of the net mask at 1 are not considered to belong to the net and they are not treated. For example, the mask 255.255.255.000 allows 256 server addresses that would share the first three values of the address.

Gateway. Link gate. It shows the IP address the messages will be sent to for those servers tat do not belong to the local net. It will be the IP address of the unit in charge of carrying out the router functions of the net.

No. of connections. It is fixed at 1.

Procome Master IP address. It shows the protection IP address (client unit).

PROTECTION FUNCTIONS. DESCRIPTION AND SETTINGS



4. PROTECTION FUNCTIONS. DESCRIPTION AND SETTINGS

4.1 PROTECTION FUNCTION LOCKING Each of the protection functions can be locked by a digital input or by a logic function (combination of inputs and/or control signals). See Programming logic signals in the Configuration section

The locking programming is carried out through console and keyboard/display as any other setting inside the corresponding function.

4.2 DIFFERENTIAL PROTECTION The differential protection will be in percent terms with harmonic restraint and instantaneous. The protection function is the same for 2 and 3 winding, and the difference lays in the calculation of the differential current (see the corresponding appendix).

The settings corresponding to the differential currents (shown as xIn) are indicated in tap steps.

The differential protection generic curve is the following one:

Depending on the step and gradient current settings, different characteristics can be obtained, for example:




4.2.1 Percent characteristic It matches the graphic section with the possibility of restraint. It can be double gradient or single gradient

The protection operation takes place when once the programmed time has elapsed, since the differential current is inside the trip area with restraint possibility (see graph) and besides, the 2nd and 5th harmonic constituents do not cause restraint.

The settings (6 tables) are:

Setting Minimum Maximum Step Notes Enable YES/NO Sensitivity (xTap) 0.15 2 0.01 See note I step 1 (xTap) 0 2 0.01 I step 2 (xTap) 0 20 0.01 1 (%) 5 100 1 2 (%) 5 200 1 Additional time (s) 0 60 0.01

Note: The sensitivity value must fulfil the following:

being In the rated current (5A or 1A). If not, the sensitivity value is automatically modified to fulfil it.

The sensitivity and step currents are shown in tap steps.

The settings are in the Console, in the Differential Protection screen.

4.2.2 Harmonic restraint

4.2.2.1 Inrush restraint The protection differentiates the inrush currents by means of the differential currents 2nd harmonic component or 2nd + 4th of the differential current according the setting selection.

When the component of the 2nd or the 2nd + 4th harmonic of the differential current in one or more phases exceed the set percent of the fundamental, the trip will be inhibited in that phase or in all of them, depending on the selection.

In order to the harmonic restrain act, the differential current of the fundamental must exceed the set minimum value set, so if it below that threshold, the harmonic restrain does not act.

Setting Magnitude Operation No Idif_2 It does not inhibit in any phase 2nd PHASE Idif_2 It inhibits only in the phases exceeding the harmonic setting.

2nd GLOBAL Idif_2 It inhibits in the three phases when any of them exceeds the harmonic setting.

2nd + 4th GLOBAL 22 )4_()2_( IdifIdif + It inhibits in the three phases when any of them exceeds the harmonic setting..

Being:

Idif_2: Idifferential 2nd harmonic

Idif_4: Idifferential 2nd harmonic
