Abstract

The invention relates to a relay protection real-time digital dynamic simulation test system based on IEC 61850. The test system comprises an upper computer, an electric system real-time digital simulator, a tested digital relay protection device and a data port. To solve the problem that according to an existing RTDS, an IEC 61850 module is not consistent with a digital relay protection device in China in the format of message data, a test port of the digital relay protection device which is based on the RTDS and can achieve data collection, data exchange and data processing is developed by means of a high-communication-precision chip and Verilog program design, and the test port, the RTDS, the upper computer and the tested digital relay protection device constitute the relay protection digital dynamic simulation test system based on the IEC 61850. As is proved by closed loop test researches and tests of a 220kV line digital protection device in a certain intelligent substation in Tianjin power grid, the relay protection real-time digital dynamic simulation test system completely meets actual requirements of projects.

Description

technical field [0001] The invention belongs to the field of electric power and relates to a real-time digital simulation test of a power system, in particular to a real-time digital dynamic simulation test system for relay protection based on IEC61850. Background technique [0002] With the development of computer network and optical fiber technology, the digital substation technology based on electronic transformer and IEC61850 standard began to be applied to the power system, and the protection devices also changed accordingly, and new digital protection came into being. In digital substations, the input signals of relay protection and other secondary devices are no longer traditional analog signals, but digital signals obtained directly by electronic transformers and merging units, and then sent to relays through Ethernet switches. Secondary devices such as electrical protection. Traditional protection test equipment and test methods can no longer meet the existing test...
