风电场功率控制策略的研究

Research on power control strategy of wind farm

风速的不稳定性和间歇性使得风电机组的输出功率具有随机性和波动性。随着风电场容量的急剧增加,导致电力系统的稳定性和电能质量受到严重影响。文中搭建了双馈风力发电机组的数学模型和控制模型,采用了磁链定向矢量控制技术和电压定向矢量控制技术,针对风电机组的功率调控能力进行了深入研究与分析,提出了双馈风力发电机组的有功和无功控制策略。仿真结果表明该控制策略是合理的、可行的。

The instability and intermittent of wind speed make the output power of wind turbine generator set random and waved. With the rapid increase of the wind farm capacity,thus,the stability of the power system and the power quality are seriously affected. In this paper,we build the double fed wind turbine mathematical model and control model,use the flux oriented vector control technology and voltage oriented vector control technology,and conduct the in-depth research and analysis aiming at the regulation and control of power in wind turbines,as a result,the active and reactive power control strategy of the doubly fed wind power generator is proposed. The simulation results show that the control strategy is reasonable and feasible.
