线路的继电保护毕业论文

设计说明书可以到我以前的回答里去看，按主接线图配置保护配置，常规配置：主变保护；母差保护，线路保护，后问保护厂家要套保护装置的标准版接线图，你选好开关，要到开关的二次标准图后就可以画二次图了，你可以参照110kV变电所的图集！！！

China's power industry, as the country's most important energy industry, has been in the priority development status, Power for the development of enterprises is also eye-catching. Power system for the rapid development of protection have made new demands, which will enable the relay to rapid development. Three-phase current protection relay is one of the important forms of protection. Based on a detailed study of three lines of defense to protect the various components and wiring, Setting calculated in accordance with the principle of derivation of the three-segment protection movements value sensitivity and duration tuning formula. and the use of mathematical tools for MATLAB software programming, Simulation of a 35 kV single-ended power supply network syllogism current protection of the setting, Finally, the software MATLAB Simulink simulation waveform technology. The simulation results show that the study syllogism current protection is an ideal line protection. It can help protect all of the interaction so that the protective properties of the best. Keywords : protection; Three-phase current protection; Setting; MATLAB Simulink simulation.
