摘要
现代晶闸管阀的高额定容量使其难以在试验室用背靠背试验回路进行试验,用合成试验回路对晶闸管阀的设计进行验证是一种替代方法。设计合成试验回路的核心在于,如何正确地再现作用在晶闸管阀上的负荷。为此,重点描述了换流阀在4种运行状态下的电压和电流负荷。ABBPowerSystems开发了一种新的合成试验回路,正确地再现了运行中施加在HVDC晶闸管阀上的电压和电流负荷。验证试验表明,该回路的设计是成功的。
Modern power thyristor valves have a high power rating and are difficult to test in a back-to-back test circuit in the test laboratory.Verification of thyristor valve design with synthetic test circuits is an alternative.The core to design a synthetic test circuit is to correctly reproduce the stresses applied on the thyristor valves.Voltage and current stresses on the thyristors under four operational states are highlighted in this paper.A new synthetic test circuit has been developed by ABB Power Systems.This new circuit reproduces the correct stresses applied on the high voltage direct current(HVDC)thyristor valves in service.Verifying tests reveal that the circuit design was a success.
