Abstract

Research is proposed on coalmine power grid safety-running in case to insure coalmine normal production. According to the Low-voltage problem now still lying in the coalmine power grid, a method combined fuzzy comprehensive evaluation with gray comprehensive evaluation is proposed, selects power grid evaluation indicators, sets the impact judgment hierarchical matrix of power grid operation, judges the coalmine power grid state in the future by those index value changes, and uses different colors to indicate different power grid states, gives early warning signals if the state is below a certain level. Simulation results show that this method can accurately determine the possible development trend of power grids.
