摘要
在配电系统的馈线上采用二次重合闸能够迅速判定并隔离故障点,恢复对非故障馈线的供电,从而提高供电可靠性。介绍了二次重合闸的原理与配置方法,并在此基础上提出二级二次重合闸的配置思路,能够进一步提高供电可靠性,满足对特别重要负荷连续供电的需要。最后,简要讨论了分布式电源接入配电系统对二次重合闸的影响及解决思路。
In distribution systems,twi-reclosures are widely employed to identify fault locations,and then restore power supply of the healthy feeders associated so as to improve power supply reliability.In this work,the principle and placement method of twi-reclosures were first clarified.Then,a new two-stage twi-reclosure scheme was presented for further enhancing the power supply reliability to some very important consumers.Furthermore,the impacts of distributed generators（DGs） on twi-reclosures in distribution systems were preliminarily analyzed.
