摘要
差动保护原理作为母线保护的基本原理已经非常成熟并普遍应用,但在数字化变电站尤其是间隔数较多的变电站,用差动原理实现母线保护存在着诸多的难题,尤其是大量数据实时传输对通讯网络提出了过高的要求。提出了一种方向原理的母线保护方案,作为一个功能插件分布于各间隔的保护测控装置中,构成一种网络保护,是一种实现起来低成本并且对网络通讯几乎不增加任何负担的方案。
Differential principle is a basical busbar protection theory and is widely used. But in digital substations especially with lots of bays,there are some difficulties to apply differential principle.The realtime transferring of too large numbers of data needs extra-requirement to communication networks. This paper proposes a directional principle bus protection scheme.As a function unit distributed in each bay IED and forming a net protection, it is a good scheme with low cost and no extra-load to communication network.
