基于大气环境质量的电网绝缘污秽等级划分

The Classification of Insulator Pollution Severity of Electric Power Grid Based on Atmospheric Quality

通过测试户外挂网绝缘子表面自然积污量及实时监测湖南省各地市近年大气环境污染物主要因子(SO2,NO2,PM10)排放状况,建立了基于大气环境质量的输电线路绝缘子等值盐密、灰密的线性理论模型,并依据该模型对湖南电网绝缘污秽等级进行划分。结果表明,大气环境质量与绝缘子等值盐密、灰密之间具有较好的相关性,可通过对区域大气环境的实时监测,来实现对电网污秽等级的划分和动态调整。

A linear theoretical model models of equivalent salt deposit density （ESDD）, non soluble deposit density （NSDD） of the transmission line insulators based on atmospheric environmental quality is established by measuring the quantity of pollution of outdoor grid insulators and real time monitoring the main factor of atmospheric environmental pollutions （S02, NO2, PMlo） of each city of Hunan province in recent years, and then the pollution severity of the insulators are classified according this model. The results show that the atmospheric environmental quality index have a good relativity to the EDSS and NSDD of insulators, and the pollution severity of the power grid can be classified and adjusted automatically, through real time monitoring the area atmospheric environment data.
