Digital Protection Relay Test System

Brief Introduction

1) can be used in IEC61850 based substation
2) can output IEC 61850-9-2LE,IEC60044-7/8 messages as well as receive and send GOOSE messages
3) With an open protocol, SMV and GOOSE messages support flexible configuration and get seamless
integration with any manufacturer's products
4) Digital output based on IEC 61850
5) Can also output 0-5V small-analog signal
6) Supports hard ware input and output to satisfy the requirements of middle-low voltage protection
devices in digital substations
7) Various combinations of digital output and small-analog signal output
8) Hardware binary-in and hardware binary-out and GOOSE, can be realized by simple configuration
9) Small-analog signal can have a overall accuracy of 0.05% typical
10) Can provide test solutions for relay protection devices with various input/output methods
11) With the simulations of abnormal process layer, sample lost frames, setting the channel quality factor,
etc., the relay tester can provide a detailed solution for assessing the correctness of the bay layer IEDs

Major Features
1) 8 pairs of SMV and GOOSE ports; multiple sets of SMV and GOOSE can be configured to the same
optical port and also can be configured to different optical ports; 10 optical serial port for FT3 input
and output port and IRIG-B code input
2) Integrate optical digital test and small signal analog test function, and can also connect to external
current and voltage power amplifier
3) Supports 8 channels of independent sampling value (SMV) message output in accordance with
IEC 60044-8 (FT3) specification, 1 channel input; supports synchronous/asynchronous transmission
mode, supports multiple transmission rates
4) Supports 8 channels of sampled value (SMV) message output in accordance with IEC 61850-9-2
specification, and sampling points output at equal intervals, fully comply the latest standards of State Grid
5) Supports 12 GOOSE outputs, 8 GOOSE inputs, it can be configured in any optical port; GOOSE
supports single point, double point, time, floating point, integral type
6) It can set individually the quality bit for each channel
7) It can simulate MU delay
8) It has virtual terminal test function
9) It has message oscillography function, it can receive and parse sampled value (SMV) messages in
accordance with IEC 61850-9-2, GOOSE messages, and realize self-loop testing of the output of the device;
it can also receive fiber signal from merging units (MU) or other IEDs and shows its waveform, amplitude,
angle and frequency in real time
10) Powerful function of message record, message on line alarm and offline message analysis
11) Support multiple GOOSE message receiving or sending
12) The receiving and sending ports of SMV and GOOSE can be arbitrarily configured, it can be configured
to send and receive at same optical port, and can also be configured as an independent transceiver.
13) It can analyze completely the protection model files (ICD, CID, SCD, etc.) to realize configuration of current
and voltage channel selection, proportional coefficients, number of ASDUs, sampling rate, GOOSE
information, etc., to simply and conveniently implement protection testing and improve work efficiency
14) With message test function of drop frame, out of step, flying point, wrong order, set quality invalid, wrong value
15) With GPS, IRIG-B, IEEE1588 synchronization time function
16) With automatic bus transfer Device calibration function
17) 12 channels of small analog signal output, it can be used to test the protective relay which receive analog
signals from various electronic transformer; or connect to power amplifiers to do comparative tests of
conventional protection and digital protection
18) 8 pairs of inputs, 4 pairs of outputs, 4 pairs of fast outputs, GOOSE message, complete closed-loop
testing for protection
19) Abundant software testing functions, it can test all kinds of microcomputer-base protection devices
such as line protection, bus line protection, transformer protection, generator and transformer protection,
as well as automatic bus transfer equipment
20) Supports standard COMTRADE format waveform playback;
