摘　　要：复合绝缘子是架空输电线路上广泛使用的设备,它的老化会给电力系统的正常运行带来威胁。电力相关工作人员需要一种能够对复合绝缘子的运行状态进行判别的方法,帮助他们确定复合绝缘子是否满足运行要求,而对复合绝缘子的定性表征就成为一种优选的表征策略。将运行后的复合绝缘子分成"满足运行要求"和"不满足运行要求",使用二值逻辑回归模型,选取合适的特征量,建立了复合绝缘子状态表征体系。Composite insulators are widely used on overhead transmission lines in China nowadays. Its aging is a danger to the normal operation of electrical power system. Power system field engineers need a method to judge the operational status of composite insulators, so as to assist them to determine whether it still can meet the operational requirement. And the qualitative characterization of composite insulators becomes a kind of optimized representation strategy. In this paper, the composite insulators after operating are divided into two categories, “acceptable” and “unacceptable”; and a binary logistic regression model is adopted; and the applicable characteristic quantity is selected; finally, the condition characterization system of composite insulator is established.
