摘要

变电站直流系统的运行可靠性直接影响到整个系统的运行安全。现场数据表明,直流系统的缺陷和事故频繁发生,往往成为电力系统重大事故的隐患。因此,有效的变电站直流系统故障应急策略显得尤为重要。本文在分析直流系统组成及典型缺陷的基础上,从故障应急电源、故障应急管理组织流程和智能检测方法提供的技术支持等方面探讨了变电站直流系统的故障应急策略。这些解决方案对于提高变电站直流系统的安全运行水平,避免因直流供电设备的缺陷造成故障的扩大是有效的。

Research on Fault Emergency Strategy for Substation DC System
The operation reliability of substation DC system greatly influences the operation safety of the whole system. The site data indicates that defects and accidents occur frequently in DC system and often become the hidden troubles of severer accidents of the power system. Therefore, the effective fault emergency strategy for substation DC system is particularly important. Based on the analysis of the composition and typical defects of the DC system, this paper discuses the fault emergency strategy for substation DC system from the following aspects: fault emergency power supply, fault emergency management organization flow and technical supports provided by intelligent inspection methods. These solutions are effective for the purpose of improving the safety operation level of substation DC system and avoiding the enlargement of fault due to the defects of the DC power supply equipments.
