摘　　要：在分析现有双馈风电机组控制策略的基础上,提出了异步模式控制策略对应的电气设计方案与主控控制策略,并采用机组功率作为双馈-异步模式切换的条件,克服了传统采用风速作为模式切换条件所面临的误动作等问题。仿真试验结果表明,该异步模式控制策略是有效的,可以拓展双馈风电机组变速运行范围,进一步提高机组在低风速段的风能利用率与发电性能,具有一定的工程应用价值。Based on the analysis of the existing doubly-fed wind turbine generator system control strategy,the electrical design and main control strategy corresponding to the asynchronous mode control strategy are proposed.Using unit power as the condition of doubly-fed-asynchronous mode switching overcomes the problems of traditional malfunctions such as wind speed as the mode switching condition.Experimental simulation results show that the asynchronous mode control strategy is effective,which can expand the variable-speed operating range of the doubly-fed wind turbine generator system,and further improve the wind energy utilization rate and power generation performance of the unit in the low wind speed section,and has certain engineering application value.
