| 摘 要： | 三相异步电动机的直接启动性能较差,启动时过高的电流会对电网和电机本身造成严重冲击.软启动器可根据需要调节启动电流的大小,确保电机平稳启动.但软启动器在使用过程中会产生大量的谐波,对设备的稳定运行及电网造成不良影响.将软启动器技术和有源电力滤波器技术相融合,可构造具有滤波功能的多功能软启动器.仿真运行结果表明,所提出的软...

| Abstract: | The performance of direct starting three-phase asynchronous motor is relatively poor.Its excessive starting current brings about impact to the grid as well as the motor itself.Soft starters can adjust the starting current as required and make asynchronous motors start smoothly.However,soft starters usually produce harmonic-rich current and have harmful effect on equipments and the grid.A kind of multifunctional soft starter combined the function of soft starter with active power filter were proposed.Simulat... |
