摘要

介绍了二次综合比较法的原理。提出一种利用时间序列分析法对电容型设备在线监测的介质损耗角正切tanδ和电容量C的测量值进行分析的方法

它通过运用数理统计的原理计算出介质损耗角正切tanδ和电容量C的一次报警值

并对该报警值采取连续报警个数的确认和修改报警值二次确认的方法进行最终的确认

可有效地减少环境和设备本身的干扰。由实际检测数据的数值实验表明

该方法是有效可行的。

Abstract

The principle of twice synthesis comparison method is introduced in this paper.A novel approach based on time series analysis for analyze tan δ and C obtained from on-line monitor of capacitive equipment is presented.The threshold value of the first warning is calculated based on mathematical statistics and is confirmed by the number of the successive warnings.The second warning is made on the threshold amended based on circumstances condition so that the disturbance caused by surroundings and monitoring system can be effectively reduced.Analysis results of experiment data have verified its effectiveness.
