摘要
为了解决由非线性负载产生的谐波污染问题,同时保证重要负载的不间断工作,提出一种全钒液流电池和有源电力滤波器相结合的统一滤波系统。该系统不仅能实现滤波和无功补偿,而且在电力中断时实现不间断电源的功能。详细分析所构建系统的工作原理和控制策略,利用Matlab/Simulink对系统进行仿真验证,并且设计一台基于数字信号处理器TMS320F28335的实验室样机。仿真和实验的结果验证该系统结构和控制方法的可行性。
ABSTRACT:A new power filter system which combines active power filter (APF) with vanadium redox battery (VRB) is proposed to solve the problems of harmonic pollution from nonlinear load and at the same time to ensure uninterrupted work of important load. This system not only can achieve functions of power filtering and reactive power compensation, but also can achieve uninterruptible power supply (UPS) when electricity interruption happens. The working principle and control strategy of the established system are analyzed in detail and the system is verified by simulation with Matlab/Simulink. Based on TMS320F28335DSP, a laboratory prototype is designed. The feasibility of the system configuration and control strategy presented above are proved by the simulation and experimental results.
