The Study On The Application Of Fault Location System In Gaoan Rural Distribution Network

With the development of economy and the improvement of peopl e's living standard,the demand for power supply reliability of power users is higher and higher.When the distribution network fails,if it can quickly locate the fault,it can improve the efficiency and reduce the power failure time.Most area of Gao'an city in Jiangxi province is a low-mountain and hilly landform,with distribution network overhead lines running through it,and there are difficulties in daily inspection,troubleshooting and maintenance of operation and maintenance personnel.As a result,the introduction of malfunctioning technology in the rural areas of the city of Gao'an,which will take the place of the original artificial circuit,providing accurate information for the precise search of the power of the distribution lines,and the importance of the safety and reliable power and the improved quality of service.This is a study on the problem of distribution network fault location.To sum up the current state of the study at home and abroad,together with the basic condition of the rural distribution network in Gao'an city,the system is designed and implemented.Firstly,the basic principle of the distribution network fault location system is analyzed,and the theoretical analysis is carried out from three aspects: the principle of current transformer,fault characteristics and fault location.Secondly,it designs a system scheme with the equipment manufacturer,expounds the architecture of the system,and analyzes the working principle,positioning method and technical advantages.Finally,it chooses eight 10 kV lines to pilot application,implementation and tracking effect and solve the problem of abnormal problems of construction site,the quantitative analysis of fault judging efficiency of this system,and the social benefit,economic benefit,and relevant conclusions,for further popularization and application of this system has certain theoretical value and significance.
