双侧电源的35KV线路继电保护的配置及整定计算
摘要
本文设计双侧电源的35KV线路继电保护的配置及整定计算。随着科学技术的飞速发展,继电保护器在35kV变电站中的应用也越来越广泛,它不仅保护着设备本身的安全,而且还保障了生产的正常进行,因此,做好继电保护的整定对于保障设备安全和生产的正常进行是十分重要的。整定计算是决定保护装置正确动作的关键环节,要满足继电保护和安全自动装置可靠性、选择性、灵敏性、速动性的要求,在不满足时应合理取舍。本设计包括线路继电保护的配置、系统的等值计算、短路电流的计算及整定计算。加强继电保护管理,健全沟通渠道,加强继电保护定值整定档案管理是提高继电保护定值整定的必要措施。
关键词:线路继电保护;短路故障;继电保护整定计算。
ABSTRACT
This design of bilateral power supply 35KV line configuration and relay setting calculation. With the rapid development of science and technology, 35kV substation relay protection device in the application of more and more widely, not only protect the safety of the device itself, but also protect the normal production, so do the relay protection tuning equipment for safety and protection of normal production is very important. Setting calculation is to determine the correct action to protect the key installations to meet the reliability of relay protection and automatic safety devices, selectivity, sensitivity, speed and mobility requirements should be a reasonable trade-off does not meet. The design includes the line relay configuration, the system equivalent calculation, short-circuit current calculation and setting calculation. Enhanced relay protection management, munication channels to enhance value setting relay records management is to improve the relay setting value setting the necessary measures.
Key words: Circuit protection; fault; relay setting calculation.
