Research On Honggutan New District Power Network Planning During2013-2017

Honggutan new district is the only city CBD central business district, the seat ofthe provincial government, municipal party committee municipal government anduniversity park, nanchang is another engine of social and economic development.Economic construction, electric power. Development relatively late in thedistribution network planning in our country, and while consciously change theoriginal "power generation, transport distribution" of the status quo, made a certainachievement, makes the whole distribution network Settings are tend to the normaland reasonable, but there are still some unreasonable factors: poor, poor foundation;Circuit structure is unreasonable, conversion complex and flexible; The decrease ofthe quality of the power supply, more trouble. This topic through the valley of redbeach district to reduce the central valley of red beach,4red states, phoenix state andwas filled with large area, an area of175square kilometers of power grid status quoanalysis, through the reasonable substation, and network programming to solve thepresent situation of power grid power supply capacity is insufficient, power gridstructure is unreasonable, poor reliability, low power quality problems.110kv andabove power grid are saturated in the goal of the rack and the next five years theannual new and retrofit projects,10kv and below power grid of networkprogramming in the next three years and each year new and retrofit projects.According to the Honggutan city’s regulatory detailed planning, combining itsfunction positioning and vision, this topic research mainly completed the followingseveral aspects:1, through the collection of the distribution network equipment andoperational data, to complete the analysis of present situation of distribution network,find out the weak links of the distribution network.2, to the planning phase of loadforecasting, including the total power and the maximum load forecasting, loaddistribution forecasting two aspects.3, on the basis of the guide for the technology ofpower distribution network planning, and the actual situation of integrated planningfor high voltage substation siting, capacity and power supply division and distributionnetwork planning of space truss structure and optimization, and the concrete projectof the annual construction and transformation of the power grid is proposed, andfinally draw the planning level years geographical wiring diagram.
