摘 要:針對(duì)變電站分期建設(shè)時(shí)存在分段備自投及主變備自投無(wú)法正確動(dòng)作的問(wèn)題,研制了一套基于自適應(yīng)策略的 10 kV 備自投裝置。該裝置基于自適應(yīng)控制策略,優(yōu)化了備自投裝置的控制邏輯,增加了雙分支開(kāi)關(guān)相關(guān)外部采樣及功能壓板,能自適應(yīng)多種 10 kV 母線接線方式,均可正確實(shí)現(xiàn)分段備自投及主變備自投功能,且在變電站后續(xù)擴(kuò)建第三臺(tái)主變后無(wú)需改造,仍可適應(yīng)運(yùn)行。通過(guò)在 110 kV 古鎮(zhèn)變電站進(jìn)行應(yīng)用,運(yùn)行結(jié)果表明該裝置具有良好的適應(yīng)性和較高的工程應(yīng)用價(jià)值。

Abstract: During the phased construction of substation, the sectionalized auto-switch-in device and the main transformer auto-switch-in device cannot operate correctly, so the paper develops a 10 kV auto-switch-in device based on adaptive strategy.The device optimizes the control logic of auto-switch-in device based on adaptive strategy, and adds external samplings and functional pressing plates of the dual branch switch.It not only adapts to various 10 kV bus connection modes to correctly realize the function of sectionalized auto-switch-in device and main transformer auto-switch-in device, but also adjusts to operation without modification after the subsequent expansion of the third main substation.The operation results of 110 kV Guzhen substation show that the device has great adaptability and engineering application.
Key words: substation; 10 kV auto-switch-in device; adaptive strategy; control logic
