"110kV变电所继电保护及自动化系统设计研究--本科毕业论文"

Based on the raw data of the 110 kV substation lines and equipment, this undergraduate thesis from Southwest University of Science and Technology focuses on the design of relay protection and integrated automation system for the substation. The design is based on the design task book and the relevant regulations and standards of national power engineering design. The work conditions and short-circuit currents of the 110 kV substation under different operating modes are analyzed and calculated. The design includes the configuration and setting design of relay protection devices for electrical primary components such as lines, transformers, and generators. The key points of the design include the analysis of original data, calculation of short-circuit currents, and the configuration of main equipment relay protection and automation devices. The calculation of short-circuit currents and the configuration of main equipment relay protection and automation microcomputer protection devices are the focal points of this design. Through this design, the main relay protection and comprehensive automation configuration of complex power grid lines are achieved. The keywords of this design include 110 kV, substation, short-circuit current, relay protection, and automation microcomputer protection. This undergraduate thesis serves as a comprehensive study on the design of relay protection and integrated automation system for a 110 kV substation, providing valuable insights and solutions for the efficient and reliable operation of power grid systems.
