| 摘 要： | 光伏并网系统由于日照强度不定,利用率不高,目前的APF装置主要应用在工业三相大功率系统中,成本高且功能单一。本文提出了一种单相光伏并网与有源滤波器的统一控制策略,在同一装置上实现光伏并网发电的同时,将系统剩余容量进行部分或全部无功和谐波补偿,提高系统利用率。仿真和实验结果验证了本文提出的无功电流和谐波电流的检测方法,以及电流环和电压环控制器的设计方法的正确性和可行性。

| Abstract: | Due to instable sunlight intensity,the utilization rate of photovoltaic grid-connected systems is not high.APF devices are used in industrial three-phase power system,with high cost and single function.This paper presents a new unified control strategy which combines single-phase photovoltaic grid-connected and active power filter.The same device achieves photovoltaic grid-connected generation,while the remaining capacity of the system for some or all of reactive power and harmonic compensation.It improves the system utilization rate.The results of simulation and experiment validate the correctness and feasibility of the reactive and harmonic current detection methods,and the current loop and voltage loop controller design methods. |
