Line protection automatic test system based on real-time digital simulation system

Abstract

The invention relates to a line protection automatic test system based on a real-time digital simulation system. The line protection automatic test system is used for automatically testing a line protection device and comprises an RTDS fault waveform simulation module and an MATLAB fault waveform analysis module; the RTDS fault waveform simulation module executes different script programs according to different test types, traverses a plurality of fault types, carries out fault waveform simulation and generates a fault waveform file in a fixed format; the MATLAB fault waveform analysis modulereads curve data and a name of the fault waveform file, compares waveform change information and waveform name information, judges whether a protection action is correct and outputs a test result; data transmission of the fault waveform file is implemented between the RTDS fault waveform simulation module and the MATLAB fault waveform analysis module by an interface of a TCP/IP communication protocol; and compared to the prior art, the line protection automatic test system disclosed by the invention has the advantages of high efficiency, good applicability, convenience for use and the like.

Description

technical field [0001] The invention relates to the field of relay protection, in particular to an automatic test system for line protection based on a real-time digital simulation system. Background technique [0002] With the continuous expansion of the scale of the power grid, the number of new equipment and equipment upgrade network tests is increasing year by year, especially for line protection tests, the number of operations is large, the task load is large, and most of them are repetitive tests, the accuracy of the operator's reading test results Often not high, which reduces the efficiency of the test. The previous test methods have become increasingly difficult to meet the needs of distribution automation devices and protection device testing. It has become an important task to realize the automatic testing of massive tasks of network access testing, obtain automatic test results, and improve the utilization efficiency and test accuracy of real-time digital simulat...

Problems solved by technology

However, the test items of the existing automatic test system are relatively single, and the factors considered in the model are few, which have certain limitations and limited applicability. Moreover, the software functions have certain limitations.

The test system is not truly automated, and still requires a lot of manual operations, which cannot fully improve the utilization efficiency of the real-time simulation system
