船舶电力系统燃气轮机组双机并联运行建模与仿真

Modeling and Simulation of Parallel Operation on Gas Turbine Sets of Marine Electric Power System

海洋船舶正朝着超大型方向发展,燃气轮机凭借其启动速度快,功率密度大等特点,正越来越多的被应用到船舶电力系统的发电系统中。同时由于全电船的出现,中压电力系统正逐渐成为大型海洋船舶电力系统的发展方向。由于电力推进船的电动机单机容量大于发电机单台容量,通常会使多台发电机并联运行,从而保证电站的可靠性以及使发电机运行在最佳状态。本文通过对以燃气轮机作为原动机的4.16k V船舶中压电力系统进行建模,同时对发电机组并车工况进行仿真。仿真实验验证了此系统模型的正确性,可以用于船舶中压电力系统运行工况的仿真和分析。

Marine vessels are developing to oversize type. Gas turbine with its speed in start, high power density and other characteristics, is increasingly applied to the power generation system for marine power system. At the same time due to the emergence of all-electric ship, medium voltage power system is gradually becoming a trend for large marine ship power system. As the single capacity for electric propulsion motor is greater than the generator single capacity, which usually makes multiple generators working in parallel operation, so as to ensure the reliability of the power station and the generator running in the best condition. This paper models the 4.16 k V ship medium voltage power system with gas turbine as the prime mover, and simulates the working condition of generator in parallel operation. The simulation results verify the correctness of the system model and can be used to simulate and analyze the operating conditions of ship medium voltage power system.
