摘要(Abstract):
母线保护装置的可靠性关系到电网系统的安全、稳定运行,在对金华变电站进行220 kV母差保护技改中,金华电网首次使用国电南自的SGB750装置。对SGB750做了简要介绍,同时对调试过程中遇到的分列逻辑问题进行了详细分析。
The reliability of bus protection concerns the safe and stable operation of grid system.SGB750 was used for the first time in the improvement of the bus differential protection in Jinhua substation.This paper introduces SGB750 briefly and presents the detailed analysis of the parse logic problem during the commissioning process.
