At present, our main grid loading rate decreases year by year, and the difference between peak and valley grows more and more. In order to ensure grid safety and stable operation, it promotes all kinds of peaking technology. 目前,我国各主要电网的负荷率逐年下降,峰谷差越来越大,为保证电网安全、稳定运行,需大力推广各类调峰蓄能技术。
However, the direct start of asynchronous motor can generate much high current, which will contaminate the power grid and injure the motor. Furthermore, when an asynchronous motor runs on light loading, the efficiency and power factor both greatly reduce. 但是异步电动机存在启动电流大,对电网和电动机本身产生严重影响,以及在轻载或空载运行状态时,功率因数和效率大大降低,造成电能浪费的问题。
