摘要
从异步电机的稳态等效电路出发,推导出了功率因数与转差角频率之间的关系。通过此关系,设计了基于恒功率因数的节能型异步电动机矢量控制系统。仿真表明,该系统动、静态性能较好,在低负载时节能效果明显。
Based on equivalent circuit of asynchronous motor in stable state , the relationship between power factor and slip angle frequency was deduced. According to this relationship, vector control system with energy-saving based on constant power factor was formed. The results of simulation indicate that dynamic and steady performance of the system were good, the energy-saving effect was especially obvious under low loads.
