摘要

本文对某大型电力船舶推进系统进行了建模和特性分析。具体来说,根据主要由发电机、配电盘、变频装置、电动机等组成的电网,完成了电力系统的建模。此外,还通过潮流分析对电力系统进行了分析。特别是对短路网络的异常运行情况进行了深入的研究,以便用短时间额定值估计短路电流,并利用保护继电器实现系统安全(IEEE Std. 141-1993)。

Power system modeling and analysis of electric ship propulsion system
This paper deals with modeling and characteristic analysis of a large powered electric ship propulsion system. Particularly, electric power system modeling has been accomplished in accordance with the electric power network mainly composed of generators, switchboards, variable frequency devices, electric motors, and etc. In addition, electric power system analysis has been performed via load flow analysis. In particular, abnormal operating condition of the short circuited network is thoroughly investigated for estimating the short circuited current with the short time rating and implementing the system safety with the protection relay(IEEE Std. 141–1993).
