摘要
在磁场定向矢量控制的基础上,对变速恒频双馈风力发电机的功率特性进行了理论分析,建立了双馈发电机功率因数、功角特性、有功功率控制的数学模型并讨论了控制参数和运行状态对功率特性的影响。仿真和实验结果基本一致,直观地反映了变速恒频双馈风力发电机的功率特性,验证了所提出的双馈发电机的功率控制模型的正确性。
Power performance of variable speed constant frequency doubly-fed wind power generator was analyzed theoretically based on field oriented vector control. The mathematic model of power factor, power angle and active power control were established and the influence of control parameters and running characteristics for the power performance were discussed. The simulations and experimental results are basically consistent, which instinctively reflect power performance of variable speed constant frequency doubly-fed wind power generator, therefore it showed that the established power control model of doubly-fed generator is correct and feasible.
