光伏并网与有源滤波统一控制系统的研究
摘要：提出一种将光伏并网与有源滤波统一控制的新型控制策略。以分布式小容量并网逆变器为研究对象,基于瞬时无功功率理论进行谐波和无功电流检测,采用SPWM电流矢量控制技术,在MATLANB/SIMULINK中对所提控制策略进行了仿真验证。仿真结果表明,该控制策略能够在保证系统以最大功率并网的同时,充分利用逆变器容量,实现负载总谐波、特定次谐波和无功电流的最佳补偿,从而提高设备利用率,改善电网电能质量。

Abstract:A new strategy for unified control of grid-connected photovoltaic and active power filter is presented. Taking a distributed small-capacity inverter as the research object, the harmonic and reactive power current are detected based on the theory of instantaneous reactive power. By using SPWM current vector control technology, the proposed control strategy is simulated and verified in the MATLANB/SIMULINK simulation environment. The simulation results show that the control strategy can guarantee the grid-connected system with maximum power, make full use of the inverter capacity, and realize such functions as the load harmonic, specific harmonic elimination and optimal reactive compensation, which improve the utilization of equipment and power quality.
