    摘 要:針對(duì)一次接線為擴(kuò)大內(nèi)橋形式的變電站在分期建設(shè)過程中,前期斷路器配置不完整的情況,提出了基于原有備自投方式的適應(yīng)性強(qiáng)的改進(jìn)方法。設(shè)置了允許有主變停運(yùn)的特殊方式,保證在特殊情形下的供電可靠性,并針對(duì)小電源接入后對(duì)備自投啟動(dòng)條件的影響,提出了頻率變化啟動(dòng)和位置不對(duì)應(yīng)啟動(dòng)的快速啟動(dòng)策略,加速了備自投的動(dòng)作過程,提升了快速恢復(fù)供電的能力。

    Abstract: Aiming at the situation that the earlier stage circuit breakers were configured incompletely in stage construction process of transformer
substations with expanded inner-bridging line as primary connection, this paper proposed the adaptable improved method based on the
original spare power automatic switching mode. The special mode was set to allow the main transformer outage to ensure the power distribution
reliability under special conditions. In allusion to impacts of small power source connection on the starting condition of spare power automatic
switching, this paper raised the quick start strategy of frequency change starting and location non-correspondence starting, which speeds up the
action process of spare power automatic switching and promotes the capacity of quick power recovery.
    Key words: expanded inner-bridging line; operation mode; adaptivity; quick starting strategy
