Changchun Urban Distirbution Network Planning Model Research And Application

Study of the distribution network the target rack is a key part of the overall plan, also bethe basis of urban distribution network construction and renovation. Scientific andreasonable space truss model is the precondition of power distribution network planning.Load rise year by year in recent years, changchun area,10kv power distribution network inmade great contributions to regional economic and social development at the same time, alsoexposed the power supply capacity is insufficient, space truss structure is weak, thereliability improvement, construction difficult problems such as. According to the aboveproblem, in this paper, the changchun city distribution network space truss model for systemdesign; And selecting typical area, the use of this topic space truss model design, the theoryand practice and analysis results. Thesis research work including the following aspects:This article first study of power network frame model, through the scientific methodand technology to seek the optimal and suboptimal solutions as the planning andconstruction, for changchun distribution network evaluation and providing a basis for theconstruction of the target network programming; Then the distribution network topologyanalysis and power supply mode, set the typical distribution network power supply modeland boundary conditions are set. Based on different connection modes in setting calculationresults are analyzed under the boundary conditions of the summary, the different powersupply model is obtained under different load density and different voltage grade and thechange trend of substation under the size of each index; Then demonstrates the transitionunder different load level of distribution network wiring mode, this paper expounds the highvoltage distribution network and low voltage distribution network in common typicalconnection model, and combined with the corresponding typical connection mode, putforward different load levels to the target space truss structure transition way; Finally, thesouth of changchun city economic development zone as a typical area, the method ofdistribution network planning model is presented in this paper to study its programmingmodel, through the distribution network topology analysis and research target rack powersupply mode, finally it is concluded that the goal of the regional distribution network frame construction implementation plan by stages, the interim measures for the construction targetrack.
