摘要
文章提出一种新型有源电力滤波功能的风力发电系统并网综合控制策略。该策略利用瞬时功率理论检测谐波电流,该电流与最大功率跟踪得到的网侧变流器电流合成,再由无差拍控制实现变流器的电流跟踪调节。在Matlab/Simulink对文章的控制策略进行了仿真,结果验证了控制策略的可行性、有效性。
A new wind power generation system grid-connected control strategy based on deadbeat control which can realize active power filtering is proposed for improving power quality and the utilization rate of full power frequency conversion wind turbine generation system. The harmonic current is calculated by the instantaneous power theory. The harmonic compensatory current and the current calculated by Maximum Power Point Tracking (MPPT) are consolidated as the reference current. A deadbeat control strategy is applied to realize the control of grid-connected inverter according the reference current. The control strategy is analyzed and verified by simulation with Matlab/Simulink. The results prove the feasibility of the strategy presented above.
