In the drawing process of underground high-voltage power supply system, the position of the bus is to complete the drawing of the underground high-voltage power supply system through the direct alignment between the high voltage outlet switch graphic element and the high voltage outlet switch graphic element, there is no independent bus graphic element. The existing topology analysis method of the high-voltage grid of coal mine based on incidence matrix cannot complete topology analysis and construct topology model of the above underground high-voltage power supply system diagrams. Network topology model of high-voltage power supply system of coal mine based on node coincidence and incidence matrix, which can solve the above problems effectively, is proposed. The simulation results show that the model can easily complete the topology identification of the power supply network of the high-voltage power supply system as well as realize the function of automatic short-circuit calculation. It has the characteristics of simplicity and high efficiency.
