Research On Substation Equipment Assessmentof Inspections

With the power industry recommend a market economy and competition mechanism, electricity supply must improve their management level, technology content, electricity services, and deduce electricity production costs, increase economic efficiency and social benefits. It raises new requirements for equipment operation and management.Inspections of substation equipment is an important part of the daily work of substation operation. Through inspections it can master the status of equipments ,detect abnormal operation and remove hidden dangers in time and improve the power supply system for the safe operation and economic performance. With the continuous development of power industry, it makes a significant increase in the workload of inspections and the number of substations. Some power supply companies are in short of operating staff. Although the non-attended station put into operation greatly reduces the cost of substation operation, the number of operating staffs and improve the working efficiency, by the "four remote" only get part of data. Therefore, regular inspections carried out on unmanned substation is essential work.By now,the substation inspection period is established by experience, lack of certain scientific, the rationality and validity of inspection work is hard to guarantee. It is hard to find defect in time if the inspection period is too long, so it increase the economic losses. On the contrary, if the inspection period is too short will result in a tremendous waste of human and material resources. Meanwhile, with the large amount of advanced equipment used in power distribution station as well as infrared temperature measurement and partial discharge test, on-line monitoring technology continues to use. The current inspection period, inspection means can not meet the quality and efficient of the operation and management. Therefore, the establishment of a rational and effective mathematical model of dynamic assessment of different substation, and thus determine a reasonable substation inspection period has important practical significance.This article focuses on a rapid increase and improved quality in the power transformation and distribution equipment industry, take use of management, power systems, multi-disciplinary theory to evaluate the power station objectively. To gradually establish a perfect assessment system of power distribution stations based on the data from Hubei Power Supply Company Of SMPEC.
