Abstract

The invention discloses a relay protection device risk assessment system and method. The method is characterized by, to begin with, collecting temperature data of operation equipment through a four-phase temperature measurement probe; sending the measured data to a PC terminal; and carrying out classification and making an effective prediction on the states of the monitored operation equipment by utilizing a distance discriminant analysis algorithm. The system constructs a framework for identification of the operating state of the relay protection equipment and integrating temperature acquisition, on-line pretreatment and equipment operating state detection, can dynamically evaluate and estimate operation status and dangerousness of relay protection equipment to be measured, can provide reference data for prevention of fault of the relay protection equipment and can prevent economic losses in advance.

Description

technical field [0001] The invention relates to the technical field of electrical equipment protection, in particular to a risk assessment system and method for relay protection equipment. Background technique [0002] With the development of my country's economy and industry, the power system has gradually developed into an intelligent network characterized by "high voltage, long distance, large capacity, large unit, and long distance". Risks caused by operational failures. Among them, the reliable operation of relay protection equipment is very important to the safety and stability of the power system. Therefore, monitoring the operation status and reliability of relay protection equipment is of great significance to ensure the power system. [0003] At present, most relay protection equipment detection devices are mainly detection equipment after equipment failure, and there is no monitoring equipment that can accurately predict the failure of relay protection equipment in...
