摘要 本文介绍了光伏逆变系统的拓扑结构,建立了基于滤波器逆变器的数学模型,为了便于分析,将abc三相静止坐标系中的方程化简为d-q两相旋转坐标系下的数学方程,对逆变器的控制结构和控制参数设计进行了简单介绍。从滤波器的原理入手,对单L型和LCL型滤波器原理进行对比分析,在设计方法上,对比传统的分步设计法,本文选择了基于粒子群算法的新型LCL型滤波器的参数设计方法,最后通过仿真分析验证了LCL型滤波器的参数设计及所研究的光伏并入配电网的逆变器电压控制策略的正确性。

Abstract:The topology of the photovoltaic inverter system has been introduced in this paper, based on mathematical model of the inverter filter, and in order to facilitate analysis, ABC in the three-phase static coordinate equation was simplified d-q mathematical equation under the two phase rotating coordinate system, structure and control parameters and control of the inverter design has carried on the simple introduction and from the principle of filter, principle of single type L and type LCL filter, this paper compares and analyzes on the design method, compared the traditional design method of step by step, this paper chose based on particle swarm optimization algorithm of parameter design method of new type LCL filter, and finally type LCL filter is verified by the simulation analysis of parameter design and the research of photovoltaic (PV) into the correctness of the inverter voltage control strategy of the distribution network.
