摘 要：隨著電網(wǎng)的發(fā)展和大容量機(jī)組的接入，烏昌地區(qū)220kV系統(tǒng)短路容量已成為影響電網(wǎng)安全穩(wěn)定運(yùn)行的主要問題。在采用高阻抗變壓器、分層分區(qū)等限流措施基礎(chǔ)上，根據(jù)不同階段的網(wǎng)架特點，進(jìn)一步采取開斷線路、加裝串聯(lián)電抗器、更換開關(guān)等方法來有效限制短路電流水平，并結(jié)合該地區(qū)自身特點給出了具體的實施方案。
關(guān)鍵詞：短路電流；限制措施；開斷線路；串聯(lián)電抗器

Abstract: Following development of power grid and large capacity machine units connected-in Urmuqi-Changji area, 220kV system short circuit capacity has become a main problem of impact on power grid safety and stability of operation. On the basis of adopting high-impedance transformers, layer making and zone making etc current restrictive measures, according to grid frame characteristics of different stages, the methods including breaking lines, installing series reactors, changing switchgears etc. were adopted further to effectively restrict short circuit current level. Combined with the area itself features, this paper gave the concrete implementation plan . 

Key words: short circuit current; restrictive measure; breaking line; series reactor
