A Regional Distribution Network Plan And Its Technical And Economic Analysis

At present,China's power industry in many parts of the substation facilities,transmission line corridors and cable channels such as land use planning has not been effectively protected,many of the local power grid development plan is not completely into the overall urban planning.Meanwhile,many business-related supply management personnel to ensure that users do not have consciousness under the premise of normal power,to take advantage of market rules combining technology with the economy seek to maximi ze profits,the distribution network to ensure competition in the electricity market is fully liberalized while maintaining a strong competitive force.The South Bank town street of Gaoyao t as a research object,an atypical way tie line to the place of the more prominent issues,most of the ring line could tie line standard way ring,though each time the line rings in three locations within the basic control But each network line loopback constitute ring ring through mutual group,instead of the standard ring tie line group,is not conducive to the operation and management program and turn power lines;Southbank Street 10 kV line dividing line does not supply the regional scope,mainly in line along both sides of the main trunk to power,while causing power lines cross the scope of the phenomenon,the scope of cross-line-powered mainly in the south central region Street;part of the assembly line transformer capacity and unable to effectively control part of the line due to power supply range compared large,more lines installed transformer capacity,causing heavy line overload.How to better meet the power needs of the community while improving economic efficiency power supply bureau market.Optimize and improve the power grid development plan,standardize each ring line,a clear division line-powered regional context,part of the assembly line of variable capacity for effective control.Reasonable power grid development plan to increase the economic benefits grid company,it is very important.This paper mainly based on the actual operation of the South Bank town distribution lines and equipment,for the past five years the line between what happened overload overloaded lines,line terminal voltage failure,the load power supply failed to classify the relevant statistical analysis and in conjunction with other regional distribution operations,and analyze South Bank town unreasonable load distribution at the relevant distribution network by deficiencies classical mathematical optimization method,and proposed distribution network planning method based on technical and economic analysis.In order to enhance system reliability and economy,in order to adapt to the rapid development of production and construction of power equipment,how to conduct urban planning of the South Bank town strategy has become an important issue that must be addressed.This paper analyzes the practical approach saturation load density Southbank Street forecasts,and predicted results provide a workable proposals to further improve the efficiency of power supply bureau,thereby increasing its economic benefits.Therefore,this paper focuses proposed: Technical and Economic Research in Distribution Network Planning Decision.
