摘要
备自投作为电网故障后快速复电的有效措施在电网中得到广泛的应用,但在有小电源接入的变电站中应用这一措施时,常规备自投方案可能难以适用。通过对网内备自投装置近几年来动作事件的梳理,按照小电源对于变电站电压支撑作用进行分类,对各类应用情况下备自投方案进行探讨,提出了解决措施和建议。
The automatic bus transfer equipment, as an effective measure of fast power recovery, has been used widely in power grids, but its usual application schemes in substations integrated with small power sources may be limited. Summarizing the tripping cases of automatic bus transfer equipments in China Souther Power Grid in recent years, and classing the equipments according to the supporting roles of small power sources to the substations, and for each kind of the equipment this paper discusses its application scheme, and gives related solution and suggestion.
