摘要
太阳能是理想的可再生能源,随着太阳能光伏并网发电应用越来越广泛,光伏并网控制技术成为新的研究热点,而不同的电路拓扑结构所采用的并网控制策略有所不同,因此本文对光伏并网发电系统的应用前景以及并网控制技术现状进行了综述,在介绍光伏并网发电系统的拓扑结构与并网控制技术工作原理的基础上,按照并网滤波器的分类分别阐述了基于L型、LC型滤波器的单级式三相光伏逆变系统的数学模型与并网电流控制策略。
The solar power is the ideal renewable energy, and photovoltaic grid-connected control has become a new research hotspot with the widespread application of photovoltalc grid-connected generation. However, the control strategies adopted in different topologies are variable. This paper reviews the application prospects of photovoltaic generation system and present situation of the existing control methods, at the same time, on the basis of the system topology and control principles, discusses the mathematical models and gridconnected current control strategies of the single stage photovoltaic inverter system based on L and LC filter respectively.
