Research On Control Technology Of Distribution Network Base On Smart Grid

Line loss.suggestions is the core of the power supply enterprise a comprehensive economic and technical indicators,is the lifeblood of the economic interests of the power supply enterprise,line loss.suggestions directly affect the company's production and operation conditions.At present,for the control of line loss research at home and abroad have done a lot of work,but mostly limited to individual electrical equipment,high voltage grid and theoretical calculation of line loss,the partial pressure of the whole power grid,low voltage power distribution lines and less line loss control decision-making research.With the development of sensor technology,computer technology,communication technology,although a few developed countries using the computer intelligent concept the line loss can be automatically calculated and decision-making,but its intellectualized degree is still insufficient.Power supply enterprises in our country in line loss management work,still need to be in a half artificial intelligence degree,only for distribution network line loss control technology in the measurement,the original fault detection,the theoretical calculation of links,its still need human intervention for analysis and decision,not form a whole distribution network line loss control system.With the idea of "smart grid" put forward in recent years,promote the degree of intelligent distribution network rapid development,has brought new opportunities for distribution network line loss control of the subject,how to distribution network line loss control and an organic combination of the smart grid,forming a set of systematic,streamline line loss control system is currently a hot research topic in the field of smart grid.This paper discusses the distribution network line loss,at home and abroad are introduced in the distribution network line loss management,smart grid development,smart grid,and line loss management,combining research status;Analysis of the current our country way of calculation and analysis on the distribution network line loss management and decision-making method,describes the current our country the defects existing in the power supply enterprise line loss calculation method and power supply enterprises for line loss calculation of the actual look forward to.As the foundation,the organic combination of line loss management and the smart grid concept,based on the smart grid distribution network loss reduction control technology of the overall framework.And based on the framework of the distribution network line loss control technology system systematically the modular design,each module loss control algorithm is derived,based on power supply company the actual line loss management,put forward with the combination of loss reduction measures to organize the implementation of process and management.This paper,taking dalian lushun district power grid as the prototype,choose the suitable distribution circuit as evaluation target in this paper,the research content of test,and with the power supply enterprise "in the same period the line loss management system","electricity information acquisition system" and "control OMS system" for the actual data platform to start modeling,the early formation of loss reduction technology architecture system combine to organize and implement the process and management measures,the actual loss reduction test,and to evaluate the results.
