基于多参数的高压电力电容器状态综合评估技术OA

This paper proposes a state monitoring and health assessment method based on multi-parameter fusion for the fault risks existing in the operation of high-voltage power capacitors.By using sensors to monitor key parameters such as operating voltage,capacitance,unbalanced current,operating temperature and partial discharge of power capacitors,it statistically analyzes the fault states of different operating parameters.Meanwhile,it uses the weighted evaluation method to analyze the monitoring data for multi-parameter fusion.The operating state of the power capacitor is judged with a threshold of 95％.The research shows that the multi-parameter weighted evaluation method proposed can effectively overcome the limitations of single-parameter diagnosis,and can more sensitively detect the fault state of high-voltage power capacitors.This enables the power capacitors with fault risks to be maintained in a timely manner,improving the reliability of reactive power compensation devices.
