摘要
本文介绍了一种基于定子(电网)电压定向的双馈风力发电机输出功率控制策略。此控制策略无需测量定子磁链,可实现发电机输出有功、无功功率的独立控制。并根据此控制方法,使用Matlab/Simulink软件构建了一个用于1.5MW双馈风力发电机的输出功率控制系统,仿真验证了在有功功率、无功功率或电网电压出现降落的条件下,该控制策略的有效性。
This paper describes a power control scheme of doubly-fed induction generator(DFIG) in wind energy conversion system. The control scheme is a kind of rotor current vector control in stator (grid) vokage oriented frame, which can control active and reactive output power of DFIG independently. The power control system using this scheme is simulated by Matlab/Simulink for 1.5MW DFIG. The Simulation results show the effectiveness of the control scheme during variations of active power, reactive power or grid voltage.
