为了解决异步电动机直接启动过程中启动电流大、需吸收电网侧无功功率、抗扰性能差等缺点,提出了一种基于静止同步补偿器进行电压调节的异步电动机综合节能优化模型。通过分析静止同步补偿装置调节电压的工作原理和性能,在此基础上基于电压调节模式提出了1种新的异步电动机节能优化方法,以实现异步电动机软启动、动态连续无功功率补偿和机端电压稳定控制。通过仿真分析并与电机直接启动进行比较,验证了所提模型的有效性和优越性。

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 vohage,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.
