URBAN POWER DISTRIBUTION PLANNING
ABSTRACT
Urban power distribution planning is the main part of power system planning and
city planning, so doing it reasonably is the prerequisite condition of realizing the
economic and social benefit to country construction and city development.
Based on the theory and method of urban power distribution planning, power load
forecasting and the optimization of substation location are mainly studied, which
influence on the quality of planning schemes. Firstly, in load forecasting, the accuracy
is improved by forming basic frame and flow of space load forecasting, and founding
the model and method of load distribution; Secondly, in substation location planning,
computations and programs of models are decided on finding the best one under
certain load, by quoting optimization theory to found mathematical model of single-
power-supply and multi-power-supply essive locating; Lastly, distribution
network planning, according to sections and substation location optimization, is
analyzed as the example of Shanghai World’s Fair and Lingang new town. Based on
the result of load forecasting, work is optimized and reliability of power
supplying is improved by setting reasonably the capacity, location, power supply
range of substation and the work. Now the two urban power
distribution plannings are essfully realized in Shanghai.
