Optimum Analysis On Urban Medium-Voltage Distribution Network In Wulateqianqh Inner Mongolia

The urban power system is the mainly load center of the electric system, and as an important infrastructure of the city it is closely related with the social economic development. Urban distribution network planning, an important part of urban master planning, should cooperate with various development planning of our city and be implement synchronously, and the goal of it is to make the development of power grid can adapt to, meet or appropriate ahead of the needs of economic development in power supply area, so as to effectively enhance city network frame structure, ensure its development goes well with municipal construction.On the basis of widely investigating related literatures, this paper has made a optimization, using ant colony optimization algorithm, for the urban medium-voltage distribution network in Wulateqianqi referred its current situation. Optimization planning of distribution network structure is a nonlinear, multiple targets and constraints problem, which involves the radial lines, network loss, power supply reliability and so on.Through the scientific planning, we can develop a power supply system which has advantages of reliable, reasonably structured, flexibly running, environmental friendly, and economic efficiency, so as to improve the capacity and quality of city power supply network, then meet the demand of economic growth and social development.
