Research On The Remote Monitoring System Of County 10kV Distribution Network Line

10kV distribution network is the most basic unit of power supply,and it is also the nerve endpoint of power supply network.Because of its complex geographical environment,wide coverage,scattered installation of equipment,and numerous low-voltage end users,it has been a blind area for power enterprises to realize remote monitoring system of distribution network,and it also brings some difficulties to the operation and management of enterprises.Although the rural power grid has been upgraded many times,due to the lack of reasonable planning and design,as well as the large difference of line equipment selection,the structure of the power grid is unreasonable,the operation mode is not flexible,and the switch protection is conffused.Especially when the line trips and grounding faults occur,it often stops one line at a time and one piece at a time,which seriously restricts the development of the local economy.Based on the analysis of the current situation of lOkV distribution network in Wugong County,the necessity and urgency of constructing 10kV distribution network monitoring system in Wugong County are put forward.The fault information characteristic matrix is established based on the transient data of the power network measured by FTU,and the fault location of the line is determined.Through the design and application of Wugong county power grid remote monitoring system,the expected purpose has been achieved.The construction of remote monitoring system for 10kV distribution network in Wugong County has thoroughly solved the problem of "blind adjustment" of county dispatching,reduced the labor intensity of operation and maintenance personnel,improved the reliability of power supply of power grid,greatly improved the efficiency and image of power enterprise management,and brought huge economic benefits to enterprises.
