摘　　要：复杂山地光伏电站具有能量密度小、占地规模大、单个发电单元容量较小和发电阵列布置分散等特点。文章通过分析光伏电站电气系统结构与组成,建立相应的光伏电站等值电路模型,选取系统内关键节点进行短路电流计算。以华东复杂山地光伏电站为例,将计算成果应用于实际工程。结果表明该方法能有效减少整个光伏电站的工程造价。The complex mountain photovoltaic power station has the characteristics of small energy density,large floor space,small capacity of single generation unit and the power generation array is distributed,etc.A corresponding photovoltaic power station equivalent circuit model is established,and the key nodes in the system are selected for short-circuit current calculation by analyzing the structure and composition of the photovoltaic power station electrical system in the paper.A complex mountain photovoltaic power station in East China is adopted as an example.The calculated results are applied to practical projects.The results show that the method can effectively reduce the project cost of the whole photovoltaic power station.
