面向新一代智能变电站分布式母线保护

Distributed Busbar Protection for a New Generation of Intelligent Substation

随着新一代智能变电站的提出与研究,作为重要元件的母线对继电保护提出了新的要求。文中介绍智能变电站分布式母线保护,提出分布式保护应用于层次化保护系统,及方向保护原理用于分布式保护。层次化保护控制系统的研发,给保护下放及分布式母线保护的应用带来机遇,同时结合高电压技术应用很广的方向保护元件技术,给母线保护配置方案带来更多的可选择性,使其更加灵活多变。

With the development and research of the new generation smart substation,it is a new challenge for the bus to protect the relay.This paper introduces the distributed busbar protection in smart substation,and puts forward the application of distributed protection to the hierarchical protection system.The development of hierarchical protection and control system,brings opportunities for the application of protection and distributed busbar protection.At the same time,combined with the application of high voltage technology in a wide range of directional protection component technology,the system also brings more optional to the bus protection configuration scheme,so that it is more flexible and changeable.
