The Research For Sources Of Pollution Characteristic Parameters In Grid And Dynamic Early Warning Monitoring Technique

With the continuous development of China's economy,transmission lines,source of pollution in substation environment increasingly complex.Research results show that the ingredients of unclean external insulation characteristics of insulator have very big effect.Traditional slop area is equivalent to NaCl and all uncleanness shall not dissolved inert substance,however,experience has shown that the equivalent are not very full,need to reconsider the unsolvable component of filth,organic content,the soluble inorganic salt and so on various components of the influence of external insulation characteristic of insulator.At the same time,along with economic development,electric power facilities and attributes,great changes have taken place in the surrounding environment,and the original clean and unclean area may into industrial pollution area,so can be combined with filth and monitoring of air quality,and other technical means,to implement the dynamic information of source of pollution surveillance and equipment monitoring,and lack of outer insulation configuration,provide early warning information,to prevent the pollution flashover accident of power grid.At present,to study the contamination ingredients are mostly concentrated in the influence on the flashover voltage in saturated moisture condition,this study from the sources of pollution components,analyzes the typical characteristics of pollution source parameters and characteristic parameters of typical pollutants and sources of data,analyzes the calculation methods of air quality model and atmospheric pollutant concentration model based on.A set of monitoring system for pollution characteristic parameters is developed,including the hardware design,the working mode and the practical application.Put forward the concept of dynamic classification of pollution areas,the development of the electronic pollution area automatic drawing module,and put forward a set of short-term prediction based on the dynamic contamination warning technology,including contamination of insulators contamination condition prediction model,haze increment prediction method,automatic monitoring station and meteorological weather forecast module,pollution source monitoring with the weather forecasting system and lightning risk assessment model prediction based on function of pollution has important significance for improving the level of safe operation of power.
