针对光伏电站的基本组成与工作原理,详细探讨了光伏电池与光伏阵列的工作特性、逆变器与并网技术的选择与控制策略,以及光伏电站的整体架构与并网方式。在动态建模方面,建立了光伏电池与阵列的动态模型,分析了光伏阵列的动态特性,并通过实测数据验证了模型参数的准确性。同时,构建了逆变器控制策略的动态模型,研究了控制策略对系统动态特性的影响,并进行了仿真验证。进一步地,整合了光伏电站并网系统各部分的动态交互,构建了系统整体动态模型,并提出了模型有效性与准确性的评估方法。
In view of the basic composition and working principle of the photovoltaic power station,the working characteristics of photovoltaic cells and arrays,the selection and control strategies of inverters and grid-connection technologies,as well as the overall architecture and grid-connection methods of the photovoltaic power station are discussed in detail.In terms of dynamic modeling,a dynamic model of photovoltaic cells and arrays is established,the dynamic characteristics of the photovoltaic array are analyzed,and the accuracy of the model parameters is verified by measured data.At the same time,a dynamic model of the inverter control strategy is constructed,the influence of the control strategy on the system′s dynamic characteristics is studied,and simulation verification is carried out.Furthermore,the dynamic interactions of all parts of the photovoltaic power station grid-connected system are integrated,an overall dynamic model of the system is constructed,and an evaluation method for the effectiveness and accuracy of the model is proposed.
