【 摘 要 】

At present, the evaluation of relay status maintenance depends on a great deal of manpower, while the data source of relay protection device and fault recorder information system (hereinafter referred to as the guarantee system) has reached the basic requirement for online monitoring status evaluation. Based on the analysis of the internal structure of the system, the automatic extraction of abnormal operation information of the protection device is realized. According to the failure mode and reliability analysis method FMEA, the evaluation index of the risk of on-line status of the protection device is proposed. In the real-time status of relay protection devices and systems quantitative assessment, the final selection of actual operating data protection device as an example to show the effect of the method.
