Aiming at the structure of high voltage power supply grid, design a system which has a ability to produce the result of short circuit calculating in a self adaptive way and is able to draw accurately the graph of intelligent power supply system of high voltage. According to the high voltage power supply graph, the system carries out a network topology self study, and obtains the topology model. In terms of the self adaptive ability to realize the multi-mode short circuit calculating, which can realize the safe operation of high voltage grid at underground coal mine. The system has been trialed in the field test and the off-line operation at the Fangzhuang No. 2 mine of Jiaozuo Mining Co. , Ltd. The result shows that the system is stable, easy to operate, maintaining and can realize the function of short circuit calculating of the high voltage grid, and contribute a lot to enhance the running efficiency of the high voltage grid.
