摘要: 针对常规备自投装置不能实现链式结构串供的多个110 kV变电站中非开环点变电站在失电时的快速恢复供电问题,提出了一种适用于常规和智能化变电站,基于区域电网实时全景信息的区域备自投新方案。具体介绍了区域备自投原理和实现方案,以及其与站域备自投、常规备自投、区域保护、区域稳控的关系等。RTDS试验及现场工程应用表明,所提出的区域备自投性能优越,能够实现区域电网发生故障时的快速恢复供电。

Abstract: The paper aims at solving the problem that the fast power recovery cannot be achieved by traditional automatic transfer switching devices when a failure occurs in an 110 kV chainlike serial power supply system. Based on regional power grid real-time information, a new solution of regional automatic transfer switching is proposed in the paper, which is applicable to traditional or smart substations. A detail discussion is made on the principle and realization of regional automatic transfer switching, as well as the relationship with substation-area automatic transfer switching, traditional automatic transfer switching devices, regional relay, and regional stability control. The RTDs test and the field project application cases provide convictive results that the regional automatic transfer switching can provide a superior performance for fast power recovery when a failure occurs in regional power grid.

Key words: substation, chainlike serial power supply system, regional automatic transfer switching, real time, regional information
