摘要
屋顶光伏并网系统是光伏发电系统的一个重要的发展方向.本文根据屋顶光伏并网系统的技术特点,讨论了光伏系统中的最大功率跟踪的实现、并网逆变器的工作原理及相关的控制策略问题,并着重对光伏系统最大功率跟踪所采用的控制策略进行了仿真研究,最后指出了屋顶光伏并网系统走向大规模应用在技术上需要满足的要求.
The grid-connected roof photovohaic system is one of important forms of the solar power system. This paper studies the realization of the maximum power point tracking（MPPT） ,the operation principle of the grid-connected inverter, the Anti-is- landing and control strategy of the related issue, according to the technical character of the grid-connected roof photovohaic system,and emphasizes on the control strategy, simulation of the MPPT. In the end,the technical requirements of the grid-con- nected roof photovoltaic system are discussed, before the large-scale application of it become a reality.
