摘要
对馈线自动化保护整定方案进行合理保护整定,能够充分发挥馈线自动化的作用,对提高配电网供电可靠性具有重要意义。为此,结合就地控制型馈线自动化保护配置现状,基于重合闸时序图法,对电压型柱上联络开关的保护整定计算方法进行探究,提出了一种柱上联络开关的快速合闸的延时策略,并给出了对应的保护整定计算方法。算例验证结果充分证明了该快速合闸延时保护整定方案在减少停电时间,提高配电网供电水平的有效性。
Reasonable protection setting of feeder automation protection setting scheme can give full play to the role of feeder automation, which is of great significance to improve the reliability of distribution network power supply. Therefore, based on the present situation of the local control type feeder automatic protection configuration, the protection setting calculation method of the voltage type pole connective switch is explored by the reclosing sequence diagram method, put forward a fast closing delay strategy of the pole connective switch and the corresponding protection setting calculation method. The simulation results show that the setting scheme of fast closing delay protection proposed can reduce the outage time and improve the power supply level of distribution network.
