The Research And Application Of County Power Distribution Automation System

With the continuous improvement of China's electric power system and the continuous establishment of the power market structure,electric power has gradually entered thousands of households as a very special product on the market,becoming a common product on the market.As power users are users of a product,they are truly serviced by the company.Objects,power companies need to provide users with safe,economical and reliable power quality,and the automatic distribution network system has emerged.With the work of urban and rural power grid construction and transformation and the maturity of foreign and domestic technologies,the domestic prefecture-level power supply enterprises have gradually matured with the electrified main station system.With the realization of the pilot technology,a large number of accumulated After the experience,under the premise of the construction of the system and the expansion of the structure,it is necessary to carry out a comprehensive analysis of the distribution network in the process of system development,and new requirements for the structural framework and system opening,with the arrival of a new round of construction climax,with the increasing number of users of the county-level power supply company's distribution network,Further research is needed on the construction of automatic system in power distribution network of county-level power enterprise users.This paper first introduces the concept of distribution automation,Network distribution automation is an important basis for improving the reliability and quality of power supply,expanding the power supply capacity,and realizing the intelligent distribution network.It is also an important means to realize the efficient and economical operation of the distribution network.the function and composition of distribution network automation system.Distribution network automation mainly divides functions into two important aspects: distribution network operation automation function and distribution network management automation.Distribution network automation mainly consists of main station,communication system and distribution network automation terminal.Secondly,it puts forward the automation construction scheme of distribution network of longyao county power supply company,introduces the current situation of longyao power network,the overall development planning goal,and designs detailed primary grid structure renovation,construction of automation main station,construction of feeder automation,and implementation scheme of distribution and communication network renovation.Finally,the centralized monitoring type is a centralized monitoring type,which can be effectively applied to the centralized monitoring feeder automation technology model.It is suitable for county-level power supply systems with high reliability requirements,mature grid structure and high load capacity like Longyao County.Finally,the implementation effect of distribution network automation is analyzed,and based on the current situation of research on the implementation and non-implementation automation level of distribution network in China,the primary consideration is to ensure the reliability of power supply,and further to ensure the minimum loss of power quality,so as to play the role of automatic fault treatment.The economic benefit of distribution automation in longyao is analyzed and the effect is good.
