摘要

详细分析了单级并网光伏系统(SSGCPS)中光伏阵列、最大功率点跟踪(MPPT)控制器和功率控制器的建模方法。建立了光伏阵列的详细模型,设计了PSCAD/EMTDC环境下的MPPT控制器和功率控制器。最后,建立了100kW SSGCPS的电磁暂态模型。仿真结果表明,仿真模型能较准确地反映实际物理设备的特性和功能,可用于大功率光伏系统的设计与研究。

Modeling and simulation of a single-stage grid-connected photovoltaic system in PSCAD/EMTDC
This paper makes a detailed analysis of the modeling method for photovoltaic (PV) arrays, maximum power point tracking (MPPT) controller and the power controller in Singlestage grid-connected PV system (SSGCPS). The detailed model of PV arrays is established, the MPPT controller and the power controller are designed under PSCAD/EMTDC environment. At last, the electromagnetic transient model of a 100kW SSGCPS is completed. The simulation results show that the simulation models can reflect characteristics and functions of the actual physical device accurately and can be used to the design and research of big-power PV system.
