摘 要
本论文主要对直岗拉卡水电站进行电气一次及发电机继电保护设计。直岗拉卡水电站的总装机功率为5×45=225MW,共四回110kv出线与系统相连。
电气一次部分,首先是根据所给出的原始资料拟定五种电气主接线方案.然后对这五种方案进行可靠性、灵活性和经济性比较后，保留两种较合理的方案，对这两种方案进行短路电流计算；接着是根据短路电流计算结果进行主要电气设备的选型以及校验，包括断路器、隔离开关、母线、绝缘子等；最后再由经济性比较确定最终的电气主接线方案。
发电机继电保护的设计是对5台发电机进行保护保护类型的配置，保护的整定计算及校验，继电器的选型。论文还附有5张AutoCAD的图纸加以说明。包括电气主接线图、室外配电装置图、发电机保护的原理接线图、展开图、保护屏的布置及端子排接线图。
毕业设计的过程是一次将理论与实际相结合的过程,通过这次比较系统全面的进行设计之后，巩固和增强了电力系统学科主干课程的理解，树立了工程设计的观念，提高了电力系统设计的能力。

The electric design and generator protection of Zhi Gang La Ka hydro-electric power
Abstract
The dissertation mainly designs the primary system and the generator ralay protection of Zhi Gang La Ka hydro-electric power.. The total power of Zhi Gang La Ka hydro-electric power is 5×45MW=225MW,connecting to system with 4 outline.
For electric primary system, firstly draw up 5 drafts of main connection lines according to the firsthand information and datum. Then compare the 5 drafts from these aspects such as reliability, flexibility and economy, and keep two more reasonable plans than others. The short circuit current calculation is carried on.. And main electric equipments including circuit breakers、disconnectors、bus、insulator etc are choosed according to the result of short circuit current calculation. Finally the economy of these two plans are compared and main electrical connection plan is determined.
Generator relay protection contains choosing the protection style of the 5 generator, setting calculation as well as the verification and confirm relay style. The dissertation attach to five AutoCAD drawings including the main electric connection, outdoor distribution equipment setting, the relay protection of generator, the decoration of protection scream.
The process of the graduation design is a process of combining the theory with practice. The comprehensive and system training is helpful to enhance and consolidate the understanding and application of the branch curriculum of the electric subject, to set up the project idea and to improve the ability of the electrical system design.
KEY WORDS: Main electrical connection, short circuit current calculation, Equipment selection, Generator relay protection
