"220KV变电站综合自动化-110KV出线保护配置设计与整定计算"

The main design on the 220 KV substation comprehensive automation and 110 KV outgoing protection is a thorough exploration of the process, principles, and methods involved in the design and configuration of the protection system. Utilizing the widely adopted principles of microcomputer protection and new methods of setting, the design delves into the selection and configuration of the main busbar system, comparing various connection methods, and selecting the most suitable option based on the project requirements. The calculation of short-circuit currents is a crucial component of the design, providing the necessary data for the selection, setting, and validation of high-voltage electrical equipment. The selection and validation of electrical equipment are primarily based on the results of symmetrical short-circuit calculations. Furthermore, the design details the principles, methods, and validation of configuration in relay protection, specifically focusing on the setting and validation of current and voltage protection for phase-to-phase short-circuit faults, as well as the setting and validation of zero-sequence current protection for ground faults. The comprehensive automation, microcomputer protection, relay protection, and setting and validation calculations are the key components of this design.
