根据光伏电池的物理模型，以及光伏阵列在不同光照强度和环境温度下的输出特性，对基于Boost电路的最大功率跟踪控制进行理论分析及实现，讨论三相光伏并网逆变器的工作原理，并在PSCAD/EMTDC中搭建三相光伏并网系统。通过使用PSCAD仿真软件对20 MW光伏发电站进行模型搭建，并对其并网过程进行仿真研究，分析其对电网电能质量所产生的影响，最后提出可行的解决方案并进行仿真验证。

Abstract

According to the physical model of photovoltaic cells and the output characteristics of photovoltaic arrays under different illumination intensity and ambient temperature, the theoretical analysis and implementation of the maximum power tracking control based on Boost circuit are carried out. The work principle of three-phase photovoltaic grid-connected inverter is discussed. And the three-phase photovoltaic grid-connected system is built in PSCAD/EMTDC. The model construction of 20MW photovoltaic power station is carried out by using PSCAD simulation software, and the simulation of the grid-connected process is carried out to analyze the impact on the power quality of the grid. Finally, a feasible solution is proposed and simulated.
