摘 要: 直流換流閥是高壓直流輸電工程的核心裝置,其額定容量很大,在進行換流閥運行試驗時,為降低試驗容量,采用合成試驗方法是一個合適的選擇。提出了一種合成試驗回路,能夠正確地再現(xiàn)換流閥實際運行的電壓與電流波形,符合運行試驗的標準,而且能夠滿足運行試驗的等效性要求。采用電力系統(tǒng)仿真軟件Matlab/Simulink 對該回路進行仿真研究,并搭建了按比例縮小的物理模擬試驗回路進行驗證,結果表明該合成試驗回路的設計是可行的,可為高壓換流閥運行試驗裝置的開發(fā)提供參考。

Abstract: Thyristor valve with large rated capacity is the core device of high voltage direct current (HVDC) transmission project. During thyristor valves performance test, in order to reduce test capacity, synthetic test circuit was adopted to meet the research needs of its test methods. A kind of synthetic test circuit was proposed to reproduce the voltage and current waveforms of thyristor valves operation accurately, in accord with standards of performance test, and the circuit met the equivalent requirements of performance test. The simulation software Matlab/Simulink of power system was adopted to study the circuit and the scaling-down physical simulation test circuit was built up to carry out performance test. The results show that the designed synthetic test circuit is feasible, which provides references for the development of high voltage thyristor valves performance test.
Key words: high voltage direct current transmission; thyristor valve; synthetic test circuit; equivalence; physical model
