摘要
用合成试验回路对GarabiⅡHVDC晶闸管阀进行了运行试验。这个由传统的背靠背直接试验回路和电压振荡回路组成的合成试验回路能够产生晶闸管阀在实际运行中承受的电流和电压。该试验回路参数的选取接近系统的实际参数。从合成试验回路所获得的样品试验结果和以前从传统的背靠背试验回路获得试验结果是相同的。然而,这种合成试验回路更具有技术上的优势,并且在经济上也优于背靠背直接试验回路。
A synthetic test circuit is used to test the Garabi II HVDC thyristor va lves.This synthetic test circuit comprises a conventional Back-to-Back direct test circuit and a voltage oscillating circuit to reproduce the current and volt age stresses that the thyristor valves could meet in service.The test circuit parameters are carefully chosen to give a close representation of the system par ameters.The sample test results from this synthetic test circuit are comparable with that acquired previously from a conventional Back-to-Back direct test circu it.However,this synthetic test circuit offers several technical advantages and i s superior to the Back-to-Back direct test circuit in terms of economy as well.
