摘　　要：为了研究光伏渗透率对船舶并网光伏电力系统电能质量的影响,采用PSCAD/EMTDC软件平台参照远洋滚装船"中远腾飞"轮并网型光伏系统进行电力系统建模仿真研究,并设定8个不同等级光伏渗透率,对比分析光伏并网切入和离网切出工况对并网电力系统暂态的电能质量。光伏并网切入对电力系统电压和频率的扰动作用显著强于其离网切出过程,且随着光伏渗透率的提高呈增长趋势。研究结果表明:该研究工作对于深入探索光伏系统与船舶电力系统并联运行的临界条件、暂态和静态稳定性以及整个电力系统的可靠性具有重要的理论指导价值。To study the influence of the photovoltaic penetration factor on the power quality of a photovoltaic power system,modeling and simulation research were carried out by adopting the PSCAD/EMTDC software platform with reference to the grid-connected photovoltaic power system of the“COSCO Tengfei“ro-ro ship.Eight different levels of photovoltaic penetration factors were set,and the transient power quality of the grid-connected power system in the case of grid-connected switch-in and grid-disconnected switch-off were compared.The disturbances caused by the photovoltaic grid-connected switch-in to the voltage and frequency of the power system were significantly stronger than those in the grid-disconnected switch-off process;these disturbances presented a growth trend following the increase in photovoltaic penetration.The research work of this paper has a great theoretical value for exploring the critical condition,transient and static stability of the parallel operation of PV system and ship electric power system,and contributes to researching the reliability of the whole power system.
