| 摘 要： | 船舶电力系统在故障发生时，发电机出口断路器跳闸对船舶电力系统是一个较大的扰动，网络中不同位置的断路器动作都会对系统稳定性造成不同的影响。数字仿真方法是研究此类动态问题的有效手段。本文利用PSCAD／EMTDC仿真软件平台，对某型船舶电力系统发电机转速及励磁自动凋节装置进行了模型及参数仿真验证，并对自定义静态负荷模型以及采用铭牌参数建模的异步电动机模型进行了仿真分析，在此基础上通过时域数字动态仿真的方法，针对某型电力系统的网络结构，以典型的系统运行方式为例，分析了发电机出口断路器分断对电力系统稳定性的影响，并进一步提出为保证系统稳定性，系统运行时应当采用的相关策略。

| Abstract: | As the malfunction happens in the Ship Power System (SPS), tripping operation itself is a large disturbance to the system, which may causes undesired system instability if it is not operated at appropriate place and time. This thesis is devoted to detailed digital simulation of one defined SPS to dis- close effects of breaker tripping operation to the system. Modeling of the generator, cables, transformer and load are discussed using PSCAD / EMTDC. Since the detail parameters is unavailable, the exciter and... |
