Health Status Evaluation of Intelligent Power Distribution Room based on AHP- Entropy method

Abstract

Nowadays multi-source data can be collected and monitored from intelligent distribution room, but the other side of automation is that, large number of intelligent distribution rooms are unattended operation, and the lack of health status evaluation brings hidden dangers to personal and property safety. it is of great economic and social value to study the health status evaluation method of intelligent distribution rooms. Based on the equipment importance theory and health index theory, this paper establishes a comprehensive evaluation index system of intelligent distribution room from four aspects: primary equipment health index, secondary equipment health index, environmental security health index and power-supply reliability index. In order to overcome the subjective problem of simple analytic hierarchy process (AHP), this paper introduces AHP- entropy method to allocate the weight of each index of intelligent distribution room. The health status assessment method of intelligent distribution room based on AHP- entropy weight method is proposed for the first time. Finally, an example of two distribution rooms in Guangzhou is given to verify the feasibility of the method proposed in this paper.
