摘要
提出一种光伏并网发电与有源电力滤波器的统一控制策略,新的系统结构和控制策略克服了目前的光伏并网发电装置白天发电、夜间停机的不足,并进一步拓展了系统的功能。该系统不但能同时实现光伏并网发电、无功及谐波补偿,而且在电网因故障停电时可以对重要负载实施电力中断补偿,以保证负载不间断的工作。文中详细分析了所提出的系统的工作原理和控制策略,利用MATLAB/Simulink对系统进行了仿真验证,并且设计了一台基于数字信号处理器TMS320LF2407的实验样机。仿真和样机实验结果验证了所提出的系统结构及控制策略的可行性。
A novel combined control strategy for both active power filter （APF） and photovoltaic （PV） grid connected generation is proposed. The shortage that PV grid connected generation at present operates during the day and has to stop at night is settled, and the functions are reinforced by the new configuration and the proposed control strategy. The proposed control strategy not only can achieve functions of APF and PV grid connected generation at the same time, but also compensate the voltage interruptions. The system configuration and control strategy are analyzed and verified by simulation with MATLAB/Simulink. The system comes true in prototype based on TMS320LF2407DSP. The results of experiment and simulation prove the feasibility of the system configuration and control strategy presented above.
