Application And Research On Operation And Maintenance Of Low Voltage Set Copy System

With the continuous development of social economy and the continuous improvement of science and technology in our country,the smart grid has been continuously developed and the system of low-voltage collecting and copying has also been gradually popularized.In recent years,low-pressure collection system has gradually developed into a smart meter collection,meter reading system.It is a kind of automation technology about power marketing.It has the functions of centralized automatic meter reading and calculation on the general tables of public variable stations,residents,etc.to facilitate the charging and settlement of the power system.On the basis of the smart grid,the information acquisition system is used to realize the unified planning,coordination and control of all aspects of the meter reading and meet the requirements of "comprehensive collection,comprehensive coverage,effective control of load and electric energy data center".The low-voltage collection system fully achieved the purpose of intelligent and intensive,effectively dealt with a series of problems such as manual meter reading,charging,and miscalculation existing in accounting,estimation and omission.As a meter reading technology,low-voltage collecting system fully reflects our country’s achievements in electric power marketing.The realization of this kind of automation function largely solved the problem of difficult meter reading in the past and reduced certain manpower and material resources Consumption.As a meter reading application tool,it involves a huge number of low-voltage customer metering devices,so its operation is more complex,maintenance and management is more difficult.In most areas,the application of low-voltage collection system is relatively good.However,once the large-scale promotion is completed,the success rate of meter reading will be reduced.Therefore,the maintenance of low-voltage collection system is very important.There are many problems in daily operation,maintenance and management of low-voltage collecting system.Therefore,it is necessary to analyze and study its operation,maintenance and management seriously,and to continuously develop and innovate it to make its technology more perfect.This paper first introduces the current situation of the application of low-voltage collection system and the maintenance and management of low-voltage collection system,in order to promote the comprehensive promotion of low-voltage collection system.Based on the actual situation of operation and maintenance of low-voltage collecting system of Foshan Chancheng Power Supply Bureau,various topics and data in the operation of low-voltage collecting system are collected through multiple channels,and the problems and weak points in the operation of low-voltage collecting system are actively discovered.Combining with the professional knowledge of operation and maintenance of low voltage collecting system,the paper discusses the solution to the problem of effective operation and maintenance in view of the existing problems and weak links in operation.In this paper,we propose some improvements such as micro-power wireless set-reading,"1-2-1" lean operation and maintenance,"double positioning and double tuning",etc.Meanwhile,in order to further standardize the operation and maintenance management of independent operation and operation,Copy of the independent operation and maintenance management model series,including job requirements,operating instructions and homework form.Market data survey report shows that the proposed measures for the operation and maintenance of low-voltage collection system effectively improve the meter reading success rate.
