| 中文摘要: |
| 对循环变流器励磁的可变速抽水蓄能机组控制系统进行了研究,阐述了总体控制方案、发电电动机的控制策略和基于循环变流器的励磁电流控制原理。仿真结果表明,交流磁链机组在电机电动和发电状态下均可以实现变速恒频运行,具有较快的功率响应速度,有功功率、无功功率和转速均可独立调节。搭建实验平台,实现了电机的转子电流控制,结果表明循环变流器可以准确地控制转子的电流。 |
| 英文摘要: |
| This paper discusses the control system for the adjustable-speed pump storage group exited by a cyclo-converter. It describes the general control scheme, the control strategy of the generator-motor group, as well as excitation current control principle based on the cyclo-converter. Simulation results show that the AC flux linkage unit can run in VSCF operation in both of motor and generator states. Fast power response is achieved, and active power, reactive power and speed can all be regulated independently. An experimental platform is established to realize control over the rotor current. The result shows that the cyclo-converter can accurately control the rotor current. |
