Type PQI-DA

ApplicationThe state-of-the-art PQI-DA Power Quality Interface for low, medium and high voltage networks is the main component of a system for carrying out all of the re-quired measurement tasks in electrical networks. The PQI-DA can be used as both a Power Quality Interface compliant to DIN EN 50160 and as a measurement de-vice for measuring all physically defined measurement quantities in AC electrical networks.The component is primarily designed to monitor special reference quantities and quality agreements between the energy supplier and the customer, as well as to re-cord, analyse and save the data.Modern voltage quality measurement devices operate according to the IEC 61000-4-30 standard. This stan-dard defines measurement methods and so provides the user with a basis for comparison.Devices from different manufacturers which function according to this standard must give approximately the same readings.The standard defines two measurement device classes.Class A measurement devices are used primarily for measurements related to contracts in customer/sup-plier relationships, while class B measurement devices can be used for determining statistical quality values. A class B device is sufficient for measurements according to EN 50160.

The PQI-DA complies with the requirements of IEC 610004- 30 for class A devices for the following para-meters.

Parameters Class• Accuracy of the voltage measurement A• Determination of the time intervals A• Marking of measurement values for events A• Harmonics, interharmonics A

Power Quality Interface for Low, Medium and High Voltage Networks

* As wall mounting housing* As DIN busbar housing

• Frequency A• Voltage asymmetry A• Event recording A• Synchronisation A (with DCF77or GPS)

In addition, three different fault-value recorders and/or fault recorders can be used.

The oscilloscope recorder stores fault records which are composed of 100 μs sampling values and whose length (information regarding the time period before and after the event) can be freely chosen.

The r.m.s. recorder stores fault records which are com-posed of the r.m.s. values of half period values (10 ms). The length of the fault record (information regarding the time period before and after the event) can also be freely chosen.

The harmonics recorder stores the corresponding harmonic spectrum of all harmonics from 2nd to 50th harmonic if a limit value (harmonic or THD of a voltage) is exceeded.

All fault records are triggered by events which can be freely defined. This enables phase-phase and phase-earth events to be recorded simultaneously.The signal voltage recorder records a freely-adjustable frequency (e.g. ripple control frequency) over a freely-selectable time range.Limit value violations can also be signalled via relays, if required.Various hardware versions are available for the input in-terface (U, I).

Current inputs for the measuring circuit (C20, C30) and for the protective circuit (C21, C31) are available.

Power Quality Interface function

DescriptionThe following input configurations can be selected:• 4 voltage transformers for conventional power quality applications (feature C00)• 8 voltage transformers for power quality applications in double busbar systems (feature C10)• 4 voltage transformers and 4 current transformers for power quality and general measurement tasks (features C20, C21, C30, C31)

Up to 255 devices can be connected to one another via the system bus (E-LAN). Connections to the REG-Sys™ voltage regulation system, EORSys Peterson coil regulation and earth-fault detection system devices are always possible.Each component has two RS 232 interfaces (COM 1 and COM 2) and two E-LAN (Energy Local Area Net-work) system/transport bus interfaces.The PQI-DA can also be optionally equipped with an in-tegrated TCP/IP interface.In this case, there is no COM 2.

A button protected against unintentional touching is provided for firmware updates.

TCP/IPThe TCP/IP or COM server interface is galvanically isola-ted from all other electrical circuits.Communication via this interface is possible with a baud rate of 100 MBaud.Parameterisation of the connection (IP address etc.) is carried out using the WinPQ parameterisation software.

RS485 InterfacesEach PQI-DA is equipped with a double E-LAN interface as standard. It provides the bus connection to PQI-DAs, REG-D voltage regulators, REG-DP Petersen coil regu-lators, or an EORSys earth fault locating system.

E-LAN (Energy - Local Area Network)Features• 255 bus stations can be addressed• Multimaster structure• Integrated repeater function• Open ring, bus or combination of bus and ring possible• Log based on SDLC/HDLC framework• Transfer rates of 62.5 or 125 kbit/s• Telegram length 10 to 30 Bytes• Average throughput approx. 100 telegrams / s

Hardware-orientated device versionsThe flexibility of the system, i.e. precisely matching spe-cific requirements, can also be achieved using the hard-ware characteristics of the input and output configura-tion.Table 1 shows the different possibilities.
