| 摘 要： | 分析了变速恒频风力发电机组的特性及运行原理.提出了在定子有功参考功率捕获最大风能的同时,确定定子无功参考功率,以提高机组运行效率、优化机组运行为目的的控制策略.在该策略中运用模糊逻辑来获得定子无功参考功率的确定值,仿真验证了该策略的有效性,其能实时调节系统的无功功率,使发电机在获得定子最大有功功率的同时,显著减少了发电机本身的损耗,提高了其运行效率.

| Abstract: | The principle of variable speed constant frequency(VSCF) wind power generation system is described. While the strategy of the output reference active power tracks the maximal power,the reference reactive power of stator is considered to be set at a certain value by which the wind power generation efficiency can be improved and also the power generator can be optimized. The fuzzy logic principles are used for efficiency optimization and performance enhancement by the control of the stator reactive power. Sim... |
