The Economy Optimization Study Of Urban Distribution Network Reliability Evaluation

Due to the rapid development of our country at present stage,when China social aspects in the face of year after year to expand the scope of application of electric power resources.Countries to support the large power consumption at the same time,also want to ensure the quality of electric power resource and security at the same time,in the process,the relevant departments of the city distribution network management system,will enable to provide comprehensive electricity use in all areas of management,when found problems related to the energy transfer,distribution network can be timely reflect and put forward relative solving measures.The reliability of urban distribution network,this paper carried out the assessment and management of the project evaluation,and the related question has carried on the introduction and explanation.This paper introduced the background and significance of the first chapter mainly studies,especially in recent years,speeding up the growth of the power load,the city became the "bottleneck" restricting the development of urban distribution network,power quality,power supply capacity and the power of the power supply reliability can't satisfy the user demand,through the current process of the development of the urban distribution network,further studies the status quo at home and abroad contrast,determines the content and the expected results of this study;The second chapter mainly through urban distribution network reliability evaluation method and the calculation of the relevant indicators,to determine the necessity of the economic evaluation of reliability assessment and related calculation method for the economic base,mainly from the reference to the power supply company to consider,it gives the concept of distribution network reliability evaluation,method,model,basic data and index system;The third chapter mainly through urban distribution network overhead line network frame and the introduction of cable line rack,relevant network reliability assessment of assumptions,compares the result of the analysis to determine the influence the outcome variables,using the model,in a typical distribution network connection mode as the breakthrough point,the key content of the distribution network of power distribution network planning for further economic and technical analysis of the spatial grid structure,on the basis of simplifying the problem of some more general conclusions;The fourth chapter mainly through the efficiency of urban distribution network reliability evaluation optimization model and evaluation research,determine the reliability of the distribution network economy mode,according to the characteristics of the actual distribution network is complicated,the reliability of the corresponding economic development comprehensive evaluation and optimization software,combined with the space truss model reliability evaluation efficiency optimization model of software application problems were analyzed,and the implementation of actual power grid and the reliability of the optimized retrofit scheme economy comprehensive evaluation,provide reliable guarantee for the urban distribution network;The fifth chapter mainly to this article are summarized,some constructive Suggestions are drawn,and the late development of urban distribution network is discussed,through the analysis of the results of the study,development situation and the research direction for the future puts forward some Suggestions.
