On the Soft Start Control Characteristics of the Water Pump Motor in a Water Plant
As important electrical equipment for the operation control of a water plant,water pump motors are usually of large quantity and capacity.The operation control mode of the water pump motors directly affects the operation and ener-gy-saving efficiency of the whole plant.The soft start control technology can significantly reduce the starting surge current of the water pump motors and ensure the smooth rising of the speed,thus reducing the impact of frequent starts of the motors on the power grid and effectively improving the production efficiency and the energy-saving performance.A math-ematical model is established for the soft start process of water pump motors.Simulation analysis is then carried out on the start control process.The results can be useful reference for the formulation of energy-saving control strategies of large motors in water supply systems of water plants.
