通过建立双馈风力发电系统网侧变换器数学模型,分析网侧变换器的控制原理,提出了基于电仿真模型网电压定向的矢量控制策略,构建电压外环和电流内环的双闭环控制系统.为了有效抑制网侧电流的谐波,在电路中增加了LCL滤波电路.基于MATLAB/Simulink搭建,仿真结果表明,该控制策略能够良好地稳定直流母线电压,实现能量的双向流动.通过对比未带滤波电路与带滤波电路的电流快速傅里叶分析图,表明带LCL滤波电路的网侧电流畸变率低于5％,很好的满足了交流侧能输出高质量正弦波形的要求.“,”By establishing the mathematical model of the doubly-fed wind power system grid side converter,a control strategy is proposed based on the grid voltage oriented vector,with the analysis of the grid side converter control principle,a double closed loop control system is built with the voltage outer loop and current inner loop.In order to effectively suppress the harmonics of the grid-side current,the LCL filter circuit is added in the circuit.Based on MATLAB/Simulink,simulation models are built,simulation results show that the control strategy can well stabilize the DC bus voltage,and realize the two-way flow of the energy.By comparing the current fast Fourier analysis diagrams with/without the filter circuit,it shows the grid-side current distortion mesh of the circuit with LCL filter is less than 5 ％,which meets the requirements that the AC side can output high quality sine waveform well.
