With the rapid economic development in our country and the constant demand for high-quality living,electricity plays an increasingly important role in our daily life.Power users put forward higher requirements on the reliability and stability of system power supply.Based on this,it has become a hot research field both at home and abroad to study the method of evaluating the reliability and economy of urban distribution system.This article combines Laiwu distribution network reliability renovation project.It studies the reliability assessment method and flow of city distribution system and analyzes its economy.Firstly,it introduces the background and significance of the topic of reliability and economic evaluation of urban distribution network.It discusses the status of research in this area at home and abroad.Second,it analyzes the basic content of urban distribution network reliability assessment.It discusses reliability metrics,evaluation algorithms,and fault models for components.And based on the project case,the overall method and process of distribution network reliability assessment are studied.It focuses on the analysis of reliability parameters,component reliability model and so on.It is for the above models and algorithms,combined with Laiwu City,the specific circumstances of the distribution network for the city distribution network reliability assessment algorithm.It uses the typical distribution network in Laiwu City to validate its validity.Second,it analyzes the conflict between the reliability and the economics of the distribution system.It focuses on the economic assessment of distribution system processes and methods,and the establishment of economic optimization model.It also uses the typical distribution network in Laiwu City for verification,indicating the effectiveness of the proposed method.Finally,it analyzes the Laiwu distribution network reliability measures.It analyzes in detail both management measures and technical measures.Firstly,it discussed the improvement of management measures.Based on the accumulated experience in operation and management of distribution network,some suggestions were put forward such as strengthening training,establishing professional standards,perfecting management system of reliability work and strengthening pre-control of power outage time.It focuses on technical measures.It proposed to strengthen the distribution network construction.distribution network status maintenance,distribution automation construction and distribution network non-stop operation and other technical measures.
