摘要
为了提高光伏电池的发电效率,采用最大功率点跟踪(MPPT)控制技术。在常规扰动观察法的基础上加以改进,提出一种滞环比较和面积差相结合的变步长算法。研究了基于Boost电路的光伏发电MPPT控制系统的原理,在Matlab/Simulink中构建MPPT仿真系统模型,通过仿真验证了该方法的可行性。结果表明:改进后的MPPT算法能有效的抑制震荡现象,且能快速的跟踪在最大功率点。
In order to improve the power generation efficiency of photovoltaic cells,MPPT control technology is used.In this paper,based on the conventional perturbation observation method,a hysteresis comparison and area difference algorithm are proposed.The principle of MPPT control system based on Boost circuit is studied,and the MPPT simulation system is built in Mat lab/Simulink.The feasibility of this method is verified by simulation.The results show that the improved MPPT algorithm can effectively suppress oscillations and stabilize the maximum power point quickly.
