【Abstract】 According to the present situation of high energy consumption of main drainage system of coal mine, a kind of energy saving drainage control scheme is proposed. The scheme combines the "peak valley" electricity strategy and pump frequency control and makes full use of the water storage capacity of the storage of water, and is realized through the fuzzy control algorithm. The simulation model of mine drainage system and the fuzzy controller are designed in Matlab/Simulink. The results show that the scheme can make the drainage system achieve the purpose of efficiency enhancing and energy saving by comparison. The simulation results show that the level curves are more close to the "W" shape, that the motors’ start-stop times and the cost of mine drainage are reduced, and that the energy-saving emission and the purpose of efficient and economical operation are achieved. The effectiveness of the proposed scheme is demonstrated.更多还原
