摘要
介绍了LCL滤波型风电并网变流器的主电路拓扑结构和数学模型,提出了采用电网电流反馈闭环控制,实现电网侧电流闭环的有功、无功功率解耦的控制策略;采用MATLAB(R2010a)建立了系统仿真模型。仿真结果及试验结果表明,采用该控制策略,对LCL滤波型风电并网变流器进行控制的有效性。
The system configuration and mathematical model of grid-connected converter with LCL-type filter were introduced.A novel control strategy was introduced which adopted grid current feedback control to decouple active and reactive power components.And then based on MATLAB(R2010a),system simulation model was established.Finally,the simulation experiment and practical result demonstrate effectiveness of this kind of control strategy.
