【摘要】：为了持续提供充裕的电能给大量原位科学仪器,设计了东海缆系海底观测试验网电力系统,建立了其核心电力元件的数学模型,并分析了其静态和暂态稳定性。采用小扰动法分析了系统静态稳定性,获得了系统静态稳定判据,证明了切负荷可提高系统静态稳定性。采用相平面法和Saber仿真分析了系统暂态稳定性,发现改变核心电力元件的特性或参数,如减小海底负荷、增大海缆等效电阻、减小海缆等效电容或增加岸基远供设备输出电压的调节时间等方法,均可提高系统暂态稳定性。研制的试验网电力系统长期运行稳定可靠,证明了系统设计合理可行。
[Abstract]:In order to provide abundant electric energy to a large number of in-situ scientific instruments, the electric power system of the submarine observation network of the East China Sea cable system is designed, the mathematical model of its core power element is established, and its static and transient stability is analyzed. The static stability of the system is analyzed by using the small perturbation method, and the criterion of the static stability of the system is obtained. It is proved that the load shearing can improve the static stability of the system. The transient stability of the system is analyzed by using phase plane method and Saber simulation. It is found that the characteristics or parameters of the core power elements are changed, such as reducing the submarine load and increasing the equivalent resistance of the submarine cable. The transient stability of the system can be improved by reducing the equivalent capacitance of the submarine cable or increasing the adjusting time of the output voltage of the offshore remote supply equipment. The test network power system is stable and reliable for a long time, which proves that the system design is reasonable and feasible.
