船舶电力系统组成及故障分析.doc

PAGE 14 内容摘要 船舶电力系统是在统一控制下船舶的电源及与之相连的电网组成，并向负载供电的系统。本文主要介绍了“育鲲”轮电力系统组成及电站自动控制，其中包括发电机结构和原理、配电设备的组成和保护功能如主开关的过载短路保护，欠压保护，逆功率保护原理；以PPU作为核心控制器的船舶电站的自动控制原理和PLC的逻辑处理过程。结合轴带发电机工作原理对“育鲲”轮电力系统中出现的轴带发电机故障造成全船失电进行故障分析，总结相关故障的原因及解决办法并取有效措施排除故障。最后对电力系统部分电路提出改进意见。 关键词： 电力系统 自动控制 故障分析 ABSTRACT: This paper mainly introduces the electrical power system and automatic control system of Yu Kun Vessel of Dalian Maritime University, including the structure and principle of generators, the composition of power distribution equipment and the protection function such as the main switch overload short circuit protection, voltage protection, and inverse power protection. On the other hand, this paper gives a brief introduction to principle of automatic control system of the hydropower station and PLC logical process, with PPU as the core of the controller. Based on the principal of shaft generator in “Yu Kun” vessel, this paper analyze the power failure of caused by the malfunction of shaft generator and summarize the reasons and solutions for this problem. At last it promotes related measures to solve this problem and some suggestions for improvement for certain circuit of power system.
