For solving such shortcomings of asynchronous motor as large starting current

reactive power absorption from network side and weak interference-resistance etc in the direct starting period

a kind of comprehensive energy-saving optimization model of asynchronous motor for voltage regulation based on static synchronous compensator is proposed. By analyzing the working principle and operation performance of static synchronous compensator regulating voltage

a new energy-efficient optimization method for asynchronous motor is proposed based on the voltage regulator model to achieve soft start

continuous dynamic reactive power compensation and the terminal voltage stability control. The effectiveness and superiority of the proposed model is verified by the simulation analysis and the results of compare with the motor started directly.
