    摘 要:針對電網短路電流超標的問題,結合天一變 220 kV 正母分段改造的工程實際提出了一種柔性限流控制技術。該技術主要基于高速開斷技術,實現(xiàn)動態(tài)調整系統(tǒng)拓撲,達到降低短路電流的目的。闡述了構成柔性限流控制技術的快速保護裝置和快速開關的原理,給出了工程現(xiàn)場的應用及組網方式,并通過兩次人工短路試驗測試快速開關與常規(guī)開關動作的時序和對短路電流的抑制效果,論證了柔性限流控制技術在工程上應用的可行性。
    關鍵詞: 柔性限流控制技術;高速開斷技術;斥力機構;人工短路試驗;電流瞬時采樣值

    Abstract: Aiming at the problem of short-circuit current exceeding the standard, a flexible current limiting control technology is proposed based on the practical engineering of 220 kV bus section breaker of Tianyi transformer substation. This technology, mainly based on high-speed interruption technology, can dynamically adjust the system topology to reduce short-circuit current. In this paper, the principle of fast protection and fast switching of flexible current limiting control technology is expounded, and the application and networking mode of engineering field are given. The time sequence of fast switching and conventional switching action and the suppression of short circuit current are tested by two artificial short circuit tests, and the feasibility of flexible current limiting control technology in engineering application is verified.
    Key words: flexible current limiting control technology; high speed interruption technology; repulsion agencies; artificial short circuit test;current instantaneous sample value
