摘要
结合光伏并网发电系统和有源电力滤波器,研究了一种既能够并网发电,又可以实现无功补偿、电网谐波电流滤除的新型系统。提出了适用于该系统的无差拍复合控制策略,并给出了该策略的原理和复合指令的计算方法。最后,搭建了仿真模型和实验平台,给出了该系统的具体实现方案。运行数据验证了系统结构和控制策略的有效性和合理性。
Combining photovoltaic grid system and active power filter,a new system is proposed,which can realize grid-connected power generation and reactive compensation and filter harmonic current.A dead-beat control strategy applying to the system is put forward,the principle of strategy and calculation method of composite instructions are given as well.Finally,simulation model and experimental platform are built,demonstrating the implementations of the system.Operation data shows that the structure and control strategy of the system's validity and rationality.
