新型IGCT直流输电换流阀运行试验研究及其等效性评估
Operation Test and Equivalence Evaluation of a Novel IGCT DC Converter
摘要
Abstract
Commutation failure(CF)is an inherent problem faced by line commutated converter high voltage direct current(LCC-HVDC).In order to solve this problem,many researches at this stage mainly focus on topology,control strategy and other aspects.There is limited research and development of new converters designed to resist commutation failure.In this paper,the research on new converter test technology based on high-power reverse blocking integrated gate commutated thyristor(RB-IGCT)is carried out.First,the principle of resisting commutation failure of the novel converter is explained,and the requirements for new power electronic devices are proposed based on the different operating modes of the novel converter.Then,using the existing type test synthesis loop platform,an operational test suitable for traditional thyristor converter is conducted and the test results are analyzed.The conclusion is drawn that most of the test items have good equivalence while the small extinction angle test and turning off test have poor equivalence.Finally,new test methods and circuits are proposed for these two special tests,providing a technical basis for the development and application of novel converters.关键词
