    摘 要:接觸網(wǎng)線路在發(fā)生故障時快速進行故障點清除對于保障高速列車的穩(wěn)定運行至關(guān)重要。分析了傳統(tǒng)的接觸網(wǎng)故障測距方法以及測距方法中存在的問題,提出了一種適用于復(fù)雜線路的高頻暫態(tài)故障測距方法,該方法在進行接觸網(wǎng)故障測距時,采用接觸網(wǎng)線路參數(shù)模型確定波速度以及合適的數(shù)學方法查找波頭,可實現(xiàn)主支線故障區(qū)分。選取上海鐵路局某復(fù)雜自耦變壓器(AT)供電線路進行仿真驗證,仿真結(jié)果表明,基于高頻暫態(tài)的復(fù)雜接觸網(wǎng)故障測距方法具有良好的系統(tǒng)適應(yīng)性,為復(fù)雜結(jié)構(gòu)的供電線路故障測距提供了理論依據(jù)。

    Abstract: It is very important to clear the fault point quickly when the catenary line breaks down to ensure the stable operation of highspeed train. This paper analyzes the existing problems of traditional fault location method for catenary and ranging method, a high-frequency transient fault location method that applys for complex circuits is put forward, when this method is in contact line fault location,it uses catenary line parameter model to comfirm wave speed and searches wave head by proper mathematical methods, then main branch fault classification is realized. A complex auto-transformer (AT) power supply line is selected for simulation verification, the simulation results show that the complex catenary fault location method based on high-frequency transientt has good system adaptability and provides a theoretical basis for the fault location of complex power supply lines.
    Key words: catenary; fault location; complex structure; high-frequency transient; AT power supply; direct supply line
