摘要
针对双馈风力发电系统中定、转子磁链定向和气隙磁场定向控制的结构设计复杂、控制精度不高等问题,详细分析了双馈风力发电系统双PWM变流器控制结构,建立网侧变流器数学模型,研究分析了网侧变流器的控制策略,并采用电压、电流双闭环控制方法对系统网侧变流器进行控制。Matlab仿真结果表明,电压、电流双闭环控制系统经过短暂的振荡之后能够快速实现电路状态的转变,达到预期效果。
Doubly-fed wind power generator system usually adopts the flux orientation, rotor flux orientation and air gap magnetic field oriented to control. The control system structure is complex and the control precision is not high. In order to further improve the control effect of wind power system, thesis for doubly-fed wind power generation system with dual PWM converter is analyzed in detail and mathematical model is established for the grid-side converter. The control strategy for the grid-side converter is studied, and the grid-side side converter is controlled by double closed loop control strategy of voltage and current feedback. The simulation results show, double closed-loop control after a transient oscillation can realize the change of state and can achieve the desired effect.
