Is restricted in the graduation project the specific request and the design time limit, this graduation project has mainly completed the adding water power plant electricity host wiring design and the proof, the short-circuit current computation, an electrical equipment choice computation, the electrical equipment moves, the heat-stable verification, the electrical equipment model and the parameter has indeed made to order the more detailed theoretical design, but analyzes few to other aspects, this will wait for in continues in the next study and the work to conduct the research. Key words Electrical main wiring; Short-circuit current; An electrical equipment. 目录 摘 要 I Abstract II 第1章 前言 1 1.1设计题目 1 1.2水电站电气部分研究的背景 1 1.3本课题的研究意义 2 1.3.1 电站电气主接线的论证意义 2 1.3.2 电气一次设备和二次设备选择及计算的意义 2 1.3.3 短路电流计算的意义 2 1.3.4 本课题研究的现实意义 3 1.4本课题的
