摘要
在分析了110 kV内桥接线和扩大内桥接线方式下的备自投逻辑的基础上,提出了一种基于扩大内桥接线备自投装置二次回路接线改造的综合回路法。该方法利用广义进线备投逻辑和广义桥备投逻辑来完成不同运行方式下的备自投动作逻辑。实验证明,该方法能满足扩大内桥接线不同方式下的逻辑需求,实现简单,适应性强。
Based on the analyses of logic conditions of spare power automatic switching in 110 kV internal bridge and expanded internal bridge main connection, a comprehensive circuit method based on the connection reform of secondary circuit of auto- matic throw - in equipment of reserve power supply in expanded internal bridge main connection is proposed. The action logic of spare power automatic switching is completed under different operation mode by using logic condition of generalized incoming line backup switching equipment and generalized bridge back - up switching equipment. The experiment shows that the pro- posed method can meet the logic demand of different operation mode in expanded internal bridge main connection, and it is simple and adaptable.
