摘要
根据高压断路器状态信息的多层次性和多因素性,建立高压断路器状态评估的层次型指标体系。利用模糊综合评判法,建立高压断路器运行状态评估模型,通过对各层评判因素的评估,综合得出断路器的具体运行状态。指标的权重先由层次分析法确定常权权重,然后引入基于均衡函数的变权模式,对常权进行修正得到变权,以提高状态评估的准确性,为高压断路器状态评估提供了一种新的思路。
The high voltage circuit breaker＇s condition messages are of multilayer and muhifactor, so a layered evaluation indexs system is built in this paper. An operation condition evaluation model for high voltage circuit breaker, which evaluates the state of every layer and gives a comprehensive assessment of circuit breaker, is established on the basis of the fuzzy comprehensive judgment. A constant weight of every index is firstly determined by the AHP method. Then by introducing the variable weight model based on the balanced function to modify the constant weight, a variable weight is obtained to improve the assessment accuracy. This study would provide a new method for high voltage circuit breaker condition assessment.
