Introduction
Methods and Materials: Dust and dust has become one of the most dangerous natural hazards in Iran in recent years and has affected the lives of the residents of this region in the west and southwest of the country and has caused irregular migration from these areas. Rainstorms also severely affect the power outlets of these areas, resulting in shorter life spans, increased maintenance costs and corrosion of power distribution equipment, which ultimately lead to extinction and widespread social consequences. At the age of fifteen, during the years 96 to 81 The ESDD practices and insulators on power NSDD Khuzestan province. For this purpose, we obtain five parameters of climatic parameters and number of dust days from meteorological organizations, concentration of pollutants from environmental organization, and amount of pollution on insulators from electricity system and by examining the relationship between annual number of days associated with dust storms and climatic parameters and pollution concentration analysis. The sites were zoned using ESDD and NSDD contaminated areas using GIS.
Results:
The results showed that the contamination status of the area was exceeded by international standards and the condition was very heavy and the concentration of contaminants reached from 2010 micrograms / m3 in 2002 to 10000 micrograms / m3 in year 96 and the main concentration of these contaminants in the areas. South of the province is between Ahvaz, Mahshahr, Abadan and Khorramshahr stations. Criterion of contamination due to frequent occurrence of high insoluble matter with high solubility is possible using both ESDD and NSDD methods and due to more power outages, dust deposition and dusts. On insulators and its combination with air humidity and The creation of sticky mud on this factor leads to a short circuit in the network. Amongst the stations, the highest number of stormy days with 64 days is related to Bostan Station due to being located in the western part of the province and close to the eastern and western regions. The Karkheh River, which has the potential to lift particles, as well as the proximity of Arab countries, has most of its foreign-origin storms, with a minimum of 22 days to Dezful Station, located in eastern Tristan, and most of its storms are due to avoiding western dust. It has internal and local origin.Methods: Dust has become one of the most dangerous natural hazards in Iran in recent years and has affected the lives of residents in the western and southwestern parts of the country and has caused undue migration. Rainstorms have also severely affected the power outages of these areas, resulting in shorter life spans and increased maintenance costs. The purpose of this study is to analyze the effects of dust and pollution during the years of 96-81 by ESDD and NSDD methods on electricity consumption in Khuzestan province. Pollution rates on insulators from power plant and zoning of polluted areas using GIS were analyzed by examining the relationship between annual number of days with dust storms and climatic parameters and analysis of pollution concentrations using the above methods.
Results: The results showed that the contamination of the area is very heavy and heavy in the southern parts of the province between Ahvaz, Mahshahr, Abadan and Kharm Shahri stations. The criterion for measuring contamination due to the frequent occurrence of highly insoluble matter microdomains is possible using both methods simultaneously. The most common cause of power outages is the combination of dust with air humidity and the formation of sticky mucus on the insulator, which results in a short circuit network. Most stormy days with 64 days are related to Bostan station due to being located in the western part of the province and in the vicinity of Arab countries, most of its storms are of foreign origin and the least with 22 days related to Dezful station located in eastern part of Tristan. Most of the storms in the western part are of domestic origin
