Mf3000 optical digital relay protection tester (non industrial control mf3000a and industrial control mf3000b) developed by Chengdu Tianjin Instrument Co., Ltd. is applicable to all digital substations complying with IEC 61850 specification. It can not only output sampling value messages based on IEC 61850-9-2le and iec60044-7/8, but also receive and send goose messages.
Open protocol, SMV and goose messages support flexible configuration to realize seamless connection with products of any manufacturer. In addition to the digital output based on IEC 61850, the tester can also output 0~7v small signal analog quantity. At the same time, the tester supports hard input and output to meet the testing needs of low-voltage protection devices in digital substations.
Various combinations of digital output, analog output, hard input / output and goose can be realized through simple configuration. The tester can provide test solutions for relay protection devices with various input / output modes. Even when the output voltage is 40mv, it can still maintain extremely high accuracy, and the overall output accuracy meets the requirements of class 0.05. Simulate the abnormal process layer equipment, flexibly set the channel quality factor, sampling frame loss point, etc., and provide a detailed solution for assessing the correct response of bay layer ied in case of abnormal process layer equipment.
