Abstract

Abstract: Status maintenance for relay protection needs the basis of a scientific and reasonable status evaluation. According to the constructing principle of status evaluation index system, the main factors which affect the status of relay protection devices and secondary loop are extracted, and a status indicator model for status evaluation is constructed. By using analytic hierarchy process (AHP) and entropy value method to determine a combinational weight, an idea of variable weight was introduced to adjust the weight of each status indicator. In addition, through building a membership function in fuzzy normal distribution of status indicators, the status of relay protection devices and secondary loop in a certain space was evaluated. The result shows that the fuzzy comprehensive evaluation method based on variable weight can accurately evaluate the status of devices and secondary loop, and then find the unhealthy ones.

Key words: relay protection, status evaluation, variable weight, fuzzy comprehensive evaluation
