| 摘 要： | 提出一种将有源滤波和无功功率补偿与光伏并网发电相结合的新型光伏并网功率调节系统。利用瞬态无功功率理论中的瞬时无功和谐波电流检测原理,采用电流矢量控制技术,以DSP数字信号处理器为基础,在30KVA光伏并网功率调节器样机中成功地实现了有源滤波、无功功率补偿和光伏并网发电三者的统一控制,使光伏并网功率调节器在向电网提供有功能量的同时也提供无功负载所需的无功能量,从而节省了设备投资,同时也改善了电网的供电质量。

| Abstract: | A novel PV grid-connected power conditioner system integrating active filter and reactive power compensation was presented.By applying instantaneous reactive and harmonic current detecting principle of instantaneous reactive power theory and adopting current vector control technology,and based on digital signal processor(DSP),the unitive control of active filter,reactive power compensation and PV grid-connected power generation was implemented successfully in the prototype of 30kVA PV grid-connected power conditioner.Hence,the conditioner can provide not only active power but also reactive power needed by reactive loads,which improves the power quality of the mains meanwhile saving the investment of the equipment. |
