摘要
逆变技术的发展是随着电力电子技术、微电子技术和现代控制理论的发展而发展。针对光伏并网过程中的直流升压、SPWM波形产生、同步锁相、逆变并网动态过程、研究了基于电网特点的FIR数字滤波、交流采样和稳定直流母线电压的数字PID控制器等技术提出了基于改进MPPT算法的控制策略并进行Simulink动态仿真。
The inverter technology develops with the development of power electronics technology, microelectronic technology and modern control theory. Aiming at the dynamic process of DC boost, SPWM waveform generation, genlock, inverter grid of photovoltaic grid-connected process, the paper studies FIR digital filtering based on grid characteristics, AC sampling and stable digital PID controller technology of DC bus voltage. This paper presents a control strategy based on improved MPPT algorithm and describes dynamic simulation with Simulink.
