摘 要:針對(duì)在電網(wǎng)關(guān)鍵線路或節(jié)點(diǎn)加裝串聯(lián)電抗器可限制系統(tǒng)短路電流的問(wèn)題,研究了母線加裝串聯(lián)電抗器的不同接線形式。提出多種接線方案,并對(duì)各接線方案在短路電流限制效果及對(duì)電網(wǎng)安全運(yùn)行的影響、適用場(chǎng)所、可靠性和經(jīng)濟(jì)性等方面進(jìn)行綜合比較,得到各接線方案優(yōu)缺點(diǎn),為后續(xù)加裝母線串聯(lián)電抗器工程提供參考。
關(guān)鍵詞:母線分段;串聯(lián)電抗器;接線方案

Abstract: Aiming at the problem that the key circuits or nodes added series reactors in power grid could effectively restrict the shortcircuit current, this paper studied on the different connection modes of busbar added series reactors. This paper proposed various kinds of connection schemes and comprehensively compared those short-circuit current restriction effects, impacts on power grid safe operation, applicable places, reliability and economy etc aspects to obtain the relative merits of each connection scheme, which provides the reference for the future busbar added series reactors project.
Key words: busbar segment; series reactor; connection scheme
