为探究光伏渗透率对船舶电力系统的影响，本文以“中远盛世”轮电力系统为研究对象，建立系统仿真模型，分析不同渗透率下的分布式光伏电源切入和切出对船舶电力系统电能质量的影响，以及三相短路故障下的船舶电力系统的瞬态响应。结果表明光伏并网切入对电力系统电压和频率的扰动明显强于切出过程，且随着渗透率提升，船舶电力系统遇到短路故障问题时更容易出现失稳。最后在满足船舶电力系统电能质量规范要求的同时，讨论了船用光伏系统渗透率进一步提高的可行性。
To investigate the impact of PV penetration on ship power systems, this paper takes the power system of the vessel “COSCO Shengshi” as the research object and establishes a system simulation model. The study analyzes the effects of distributed PV power integration and disconnection on power quality under different penetration levels, as well as the transient response of the ship′s power system during a three-phase short-circuit fault. The results indicate that PV power grid integration causes more significant disturbances in system voltage and frequency compared to the disconnection process. Furthermore, with increasing penetration levels, the ship's power system becomes more prone to instability during short-circuit faults. Finally, the feasibility of further increasing the PV system's penetration while meeting marine power quality standards is discussed.
