1.5 MW变极双绕组风力发电机运转无力分析

Analysis on Weak Running of the 1.5 MW Pole-changing Double-winding Wind Turbine Generator

通过1.5 MW变极双绕组风力发电机运转无力问题的分析及解决,得出变极电机双绕组设计中应充分考虑电磁兼容,避免环流产生的结论,同时提出了通过同相线圈组合理串并联消除环流的解决方案。

Through analyzing the weak running of the 1.5MW pole-changing double-winding wind turbine generator and solving this problem,came the conclusion that electromagnetic compatibility should be taken into account to eliminate the circumfluence when designing the double-winding of pole-changing motors.The reasonable series and parallel connection in the same phase winding could be used to eliminate the circumfluence.
