摘要: |
分析了高压长距离输电线路的分布电容在短路暂态过程中对快速母线差动保护动作特性的影响。指出分布电容在短路暂态过程中引起的振荡高频分量,可以导致快速母差保护拒动,其影响在保护设计时应引起重视。RCS-915型母差保护装置的保护方案考虑了线路分布电容的影响。 |

Abstract: |
This paper analyzes the influence of fast busbar differential protection caused by distributed capacitance in high-voltage long-distance transmission line during transient process. The high frequency component caused by distributed capacitance in transient process, may result in maloperation of busbar differential protections,which should be taken seriously in designing of RCS-915 differential protection. |
