摘要
俄罗斯800MW机组БРЭ1301.01定子接地保护方案比较特别,整定办法复杂繁琐,加之俄罗斯说明书讲解不详,造成有些单位在没有定值整定书的情况下运行。本文结合国内外同类保护,介绍该保护原理、归纳整定办法,并对该保护的优缺点进行了分析,旨在指导现场生产人员学习、整定计算之用。
The scheme of the 800MW generator stator ground protection is special, and its setting method is complicated.In addition, the manual supplied by Russia is not very detailed. So some of these relayings have been in operation whilethe books for setting are not available. Aiming at these phenomenon, this paper introduces the protection theory, sums upsetting method, and analyzes the protections advantage and weakness. The purpose is to provide references for engineersto study the setting and calculating of the protection.
