Sampling Failure Analysis and Countermeasure Research of Relay Protection Device

继电保护是电力系统安全的第一道防线,要快速切除故障源,减少或消除故障带来的不利影响。通过对继电保护装置的采样故障进行分析,阐述继电保护装置常见的故障和中试过程中出现的故障过程以及处理措施,并分析装置出现故障的原因,根据故障分析对装置元器件进行失效分析,确定采样故障产生的根本原因,从而确定最终对策。本研究的研究结果对继电保护装置的软硬件设计具有一定的借鉴意义。

Relay protection is the first line of defense for power system security. It is necessary to quickly remove the fault source and reduce or eliminate the adverse effects caused by the fault. Through the analysis of the sampling fault of the relay protection device, this paper expounds the common faults of the relay protection device and the fault process and treatment measures in the pilot test process, and analyzes the causes of the fault of the device. According to the fault analysis, the failure analysis of the device components is carried out to determine the root cause of the sampling fault, so as to determine the final countermeasures. The research results of this study have certain reference significance for the hardware and software design of relay protection device.
