The Power System Optimization Research Of Datong Coal Mine

To compare with the domestic developed cities, power grid construction of datong coal mine lacks of long-term optimization. And network structure are many weak links. Through the reconstructing electric power network, it can not only increase economic efficiency, but also can improve power supply reliability and quality. Power network optimization is the basis for reconstructing electric power network. If it is planed reasonably, it can improve the economic efficiency in the same time and achieve a strong electric network.This article analyzes the domestic and foreign research condition of the power network planning and discusses the concept, step and method which is of the risk assessment of power network planning. On the basis of consulting to a great deal of related data,analysizing electric main- line diagram of datong coal mine power grid, according to regions,inputting data to Power System Analysis Software Package, forming primary and common database, and choosing a kind of power flow style and calculating to get a more suitable result,which is initial value of transient stability. And by calculating the results of power balance analysis and power quality analysis, it proposed an optimization solutions. Finally, this article optimizes the program for another power flow calculation to verify the correctness of optimizing the program.
