摘　　要：在假设并网光伏电站各交流器件的输出和输入变量只含有基波分量的前提下,提出了一种利用相量法和受控源法模拟并网光伏电站电能转换及传输系统特性的方法,并建立了包含光伏阵列,具有最大功率跟踪功能的逆变器、变压器及控制系统的并网光伏电站整体仿真模型。通过采用国内某地并网光伏电站的实测数据进行的仿真验证及误差分析可知,所提出的光伏电站模拟方法和数学模型是有效的。Based on the assumption that the input/output variables of all AC devices in the PV station are of fundamental frequency, a method to simulate the operation characteristics of PV station＇s power conversion and transmission system is proposed. Phasor analysis and controllable power source theory are applied in the proposed method. A model is developed consisting of PV arrays, power inverters with maximum power point tracking function, transformers and control system. Comparison results between the measurement data and simulation results from a real PV system validate the proposed model.
