高速铁路牵引变电所并行智能化保护系统方案选择

高铁牵引变电所保护系统是高速铁路牵引供电的安全保障核心,如何开展既有高速铁路牵引变电所保护系统改造,最大程度地保障高铁运营安全,并适应高速铁路智能化发展需求,已成为牵引供电专业亟需解决的问题。本文分析了高速铁路变电所保护系统改造的特殊需求,针对牵引变电所智能化保护系统的不同方案进行了多重对比分析,提出了建议方案,为后续大量高铁牵引变电所保护系统更新改造提供参考。

The protection system of high-speed railway traction substation is the core of the safety guarantee of high-speed railway traction power supply.How to carry out the transformation of the protection system of existing high-speed railway traction substation to ensure the operation safety of high-speed railway to the greatest extent and meet the needs of intelligent development of high-speed railway has become an urgent problem to be solved by the traction power supply system.The paper analyzes the special requirements of the transformation of the protection system of high-speed railway substation,makes multiple comparative analysis on different schemes of the intelligent protection system of traction substation,and puts forward the proposed scheme,which provides a reference for the renewal and transformation of the protection system of a large number of high-speed railway traction substations in the future.
