| 摘 要： | 模块化多电平换流阀(modular multi-level converter,MMC)作为统一潮流控制器(unified power flow controller,UPFC)系统中的关键设备,其运行的可靠性直接影响到整个系统的安全稳定运行。采用k/n(G)可靠性模型描述方法,清晰地描述了换流阀可靠性与各种冗余度之间的关系,定量计算了500 kV苏南UPFC换流阀的可靠性指标,并对换流阀可靠性进行了优化设计,满足500 kV苏南UPFC工程要求,并为UPFC换流阀冗余度设计和优化提供了参考依据。

| Abstract: | As the key equipment of UPFC,the reliability of the modular multilevel voltage sourced converter operation directly affects the safe and stable operation of the whole AC system.An k-out-of-n:G system model of Sunan 500 kV UPFC-MMC and the basic analysis method for it are proposed in this paper.The relation between the reliability of valve and different redundancies is clearly described.The reliability value and MTTF of Sunan 500 kV UPFC-MMC are evaluated.And the optimal amount of redundant sub-module is analyzed basing on the indices obtained in forenamed study.The reliability design optimization of MMC valve could meet the engineering requirements Sunan 500 kV UPFC and would provide a reference for follow-up project. |
