At the same time, various kinds of circuit protection come into being. Since relay setting calculating and automatic equipment may differ from one another as a result of producers, therefore, whether they can work well makes great influence on the stability of the power industry. Some statistics has shown that a large proportion of accidents in the power industry are caused by relay setting calculating, for Three Errors, caused by setting calculating and improper management, happen from time to time. Hence, it is vital for us to explore the approaches on relay setting collocation and setting calculating. As we know, setting calculating is the core in the process of checking protection equipment, which needs to make the relay setting calculating and automatic equipment reliable, selective, sensitive, quick-act. And if the requirements can not be reached, we need to select setting calculating. My graduation design will consist of the collocation of circuit setting protection, the equivalent calculation of system, and the calculation of short circuit current as well as the setting calculation. 目 录 ABSTRACT 3 第一章 绪论 5 1.1 研究该课题的意义 5 1.2 课题的解决方案及手段 5 1.3 本论文的主要工作 5 第二章 线路继电保护 6 2.1 继电保护的简介 8 2.2 继电保护的发展现状
