摘要
柔性直流输电技术是未来输电技术发展方向,其具有占地面积小,谐波小,模块化等优点,因此受到广泛的关注。高压换流器作为高压柔性输电的关键器件,对其可靠性的研究具有十分重要的意义。本文在分析高压换流器中关键器件的结构以及其可靠性评价的基础上,利用马尔可夫模型对高压换流器的可靠性进行建模分析,得出其可靠性评估方法。
Flexible DC transmission technology is the direction of development of transmission technology. It has the advantages of smaller,lower harmonic,modularization and so on,so it has received extensive attention. As the key device of high voltage flexible transmission,the research on the reliability of high voltage converter is very important.Based on the analysis of the structure of the key devices and the reliability evaluation of the high voltage converter,the reliability of the high voltage converter is modeled and analyzed by markov model,and the reliability evaluation method is obtained.
