Feeder Automati On Technology Research And Application In Distribution Network At The County Level

With the rapid improvement of national living standards,the rapid increase in household electricity consumption,users increasingly improve the quality of services,power quality,power supply reliability standards,the existing operating mode of the power system has been difficult to meet the safety,quality and economic operation Requirements,therefore,power companies continue to improve the continuous power supply capacity,choose a more stable,efficient and orderly form of energy supply to the majority of users is necessary,especially with the user most closely related distribution network,but also need more reliable Technical Support.In this premise,to produce a feeder automation as the main content of the distribution network automation technology,its production is to adapt to social progress,but also highlights the power of high-speed development of science and technology an important symbol.This paper begins with a brief description and elaboration of the origin,development status and research significance of distribution automation and feeder automation technology.Then,the paper analyzes the key technologies in the feeder network automation,and puts forward the appropriate feeder automation control mode to transform the actual situation of regional distribution network in Shanghe County.In view of the problem of small current grounding fault line selection,In this paper,the fault location algorithm based on wavelet energy is applied to improve the accuracy of fault location selection.Then,according to the topology and current situation of regional distribution network of Shanghe county center,the feeder automation scheme of feeder network is studied,and the transformation target and principle are put forward,and the equipment of all levels is carried out.Transformation.After the operation of the feeder network automation in the county center of Shanghe County,the simulation results of the wavelet energy fault detection algorithm,the FA mode application and the typical line fault processing,the calculation and comparison of the main indexes of the power supply reliability before and after the system The results show that the reliability of the distribution network is significantly increased and the reliability of the power supply is greatly increased.The feeder automation system can quickly complete the detection,positioning and isolation of the fault zone to ensure the distribution of the power distribution system.The normal operation of the network and the continued power,high-quality supply.
