Automatic Detection System of Substation Relay Protection Device Based on Failure Density Function

Abstract

Because the traditional substation relay protection device automatic detection system has the problem of inaccurate detection results, the substation relay protection device automatic detection system based on the failure density function is designed. The hardware structure of the system is designed by the high-performance C8051F040 single chip microcomputer and the insulation detection sensor. On the basis of the system hardware design, the system software function is optimized. According to the relay protection current setting calculation flow, the genetic algorithm is derived to construct the failure density function, and the automatic detection of the relay protection device in the substation is carried out, Through the hardware design and software design of the system, the design of automatic detection system of substation relay protection device based on genetic algorithm is completed. The experimental results show that the designed system can detect the insulation voltage of positive and negative bus more accurately and has high practicability in the practical application process, which fully meets the research requirements.
