摘　　要：大量光伏电站的并网,相应地带来并网稳定性、自身抗扰动性等相关问题。由于单级型光伏并网系统和双级型光伏并网系统的拓扑结构不同,其并网运行的动态特性也不尽相同。文章基于PSCAD/EMTDC电磁暂态仿真软件,分别搭建单级型和双级型光伏并网系统模型,并对比仿真了光照扰动与电网电压跌落扰动下两种光伏并网系统的动态特性,单级型光伏并网系统更适合于大中型光伏电站。With a large number of photovohaic power stations connected to the grid, some problems such as the grid-connected stability, anti-disturbance, etc. brought out by it. As the different topology of single and double stage photovoltaic grid-connected system, the dynamic characteristics are also different. Based on PSCAD/EMTDC, single-stage ＆ double stage photovoltaie grid-connected systems were set up in this article, the dynamic characteristics were compared and simulated as grid voltage drop and disturbance of lighting, the single stage photovoltaic grid-connected system is more suitable for large or middle scale photovohaie power station.
