摘要
针对当前大型永磁直驱风力机(W ind Energy Conversion System,WECS)的实际应用困难,提出1种新的永磁半直驱WECS.该系统在大风力机与永磁同步发电机(PermanentMagnet Synchro-nous Generator,PMSG)之间增加小增速比的齿轮箱;采用PWM AC-DC变流方案及SVPWM控制技术;控制策略目标为实现最大风能捕捉和高功率因数并网.系统并网控制仿真表明,永磁半直驱WECS控制策略可行.
For the difficulty of applying the conventional large scale direct-drive permanent magnet Wind Energy Conversion System （WECS） , a new half-direct-drive permanent magnet WECS is proposed. In this system, a gear box with little velocity ratio is used between WECS and Permanent Magnet Synchronous Generator （PMSG） ; PWM AC-DC converter and SVPWM control technology are used; and the control strategy object is to catch greatest wind and high power factor in grid connected operation. The simulation of the systematical grid connected operation control shows that the proposed half-direct permanent magnet WECS work is feasible.
