基于原屏方案的500kV升压站继电保护装置改造系统设计

Design of 500 kV Substation Relay Protection Device Renovation System Based on Original Screen Scheme

在电力系统中,500 kV升压站扮演着至关重要的角色,其继电保护装置可确保系统在故障发生时能可靠、迅速、准确地切断故障部分,保障发电厂和电网的安全稳定运行。随着科技的发展,传统的继电保护装置已逐渐不能满足现代电网发展的需求,需通过技术改造来提升其性能和智能化水平。基于原屏方案的改造,即在现有设备和架构的基础上进行升级和优化,是一种既经济又有效的策略。这种改造不仅涉及硬件的更新换代,还包括软件和系统集成技术的进步,特别是在数字化保护与智能控制方面的应用。详细介绍了基于原屏方案的500 kV升压站继电保护装置的改造系统设计,涵盖了从系统架构、数字化保护与智能控制,到系统集成设计及改造设计的实现过程,全面阐述了改造的方案、技术应用及期望达到的效果。

In the power system,500 kV booster stations play a crucial role,and their relay protection devices can ensure that the system can reliably,quickly,and accurately cut off the faulty part in the event of a fault,ensuring the safe and stable operation of power plants and the power grid.With the development of technology,traditional relay protection devices are gradually unable to meet the needs of modern power grid development,and their performance and intelligence level need to be improved through technological transformation.The transformation based on the original screen solution,which involves upgrading and optimizing existing equipment and architecture,is an economical and effective strategy.This transformation not only involves the upgrading of hardware,but also the advancement of software and system integration technology,especially in the application of digital protection and intelligent control.This paper provides a detailed introduction to the design of the renovation system for the relay protection device of a 500 kV substation based on the original screen scheme,covering the realization process from the system architecture,digital protection and intelligent control,to the system integration design and the renovation design,the renovation plan,technical applications,and expected results are comprehensively elaborated.
