摘 要:基于雙母線四分段主接線方式,提出了一種四臺主變互為備自投功能的邏輯控制策略,給出具體設(shè)計(jì)方案,在完成基本備自投功能的基礎(chǔ)上增加了備自投過程中的同期判斷功能和備自投成功后的過載切負(fù)荷功能,并在備自投過程中考慮了可備自投開關(guān)優(yōu)先級問題。該備自投功能已在SCS-500 備自投裝置上實(shí)現(xiàn)并成功應(yīng)用。

Abstract: Based on dual-busbar four-section main wiring method, this paper raised a logical control strategy of four main transformers in mutual auto-switch-on function, giving the actual design plan. On the basis of finishing the basic auto-switch-on function, the synchronous judgement function in auto-switch-on process and over-load switch-off function after success of auto-switch-on were added, and in autoswitch-on process possible switch-on switch priority was taken into consideration. The SCS-500 auto-switch-on device has realized the autoswitch-on function.
        Key words: four main transformers; auto-switch-on; synchronism; switch priority; overload switch off
