Research On General Analyzing And Simulating Verification System Of Relay Protection

With the development of power system, the development of relay protection is very fast, it is difficult to satisfy the demand of relay protection which comes from the power system. This paper introduces a general analysis and emulation verification system of relay protection. The system designing is based on object-oriented technology, and can managed to general analyze and emulation verify. The analysis part including data processing, fundamental wave analysis, harmonic analyses, sequence analysis, impedance trace, fault analysis and so on. The second part adopted modular design and database system technology, and it makes full use of computer software to simulate actual protection devices, it take simulation data which come from DDRTS and the recorded data of COMTRADE format as input data, Through the soft construction which equal to real relay protection devices, it can simulate the action process and result.
