摘　　要：光伏发电是新能源发电的一种主要形式;以前主要以小容量光伏电站独立或并网运行方式为主。目前,随着低碳电力发展的要求,以及光伏及并网技术的快速提高,发电成本快速下降;大容量MW级光伏电站并网运行已经出现;对接入地配电网的安全稳定运行带来新的问题。本论文结合山东电网中MW级光伏电站并网的发展现状,通过详细分析光伏组件及变换器的数学模型,建立了MW级并网光伏电站的整体稳态数学模型,并在此基础上,结合IEEE-10机-39节点系统对10MW的光伏电站并网进行了静态潮流,分析了MW级光伏电站在不同点接入配网时对配电网的影响。本文的研究工作对推动大容量光伏电站在电网中的应用具有积极的意义。Photovoltaic（PV）generation is a major form of renewable energy generation.It was mainly the small-capacity PV staion to run stand-alone or grid connected Now,with the requirements of low-carbon power development,as well as the rapid improvement of photovoltaic power plant have em erged.It brings power plant in MW-class status.Through detailed analysis of the PV model.Combined with the New England 10-machine 39-bus system,the security station access to distribution netwoks at different points was simulated and analyzed.This paer has positive significance on the promotion of grid connected large-capacity PV station.
