摘要: |
概述柔性直流输电技术(Voltage Sourced Converters High Voltage Direct Current, VSC-HVDC)的研究现状,从模块化多电平换流器(Modular Multi-level Converter, MMC)的子模块(SM)冗余配置方法、系统拓扑结构、控制保护以及故障分析等方面进行阐述。根据实际情况说明该研究的必要性。介绍并推导马尔可夫过程,结合马尔可夫过程针对某直流输电工程的主接线方式提出一种可靠性分析模型。最后,通过在Matlab中编写程序实现了对所建模型的计算。所得结果和ABB公司的统计资料进行对比,验证了所提出的方法适用于柔性直流输电系统可靠性分析。 |

Abstract: |
This paper summarizes the status quo of studying VSC-HVDC, and discusses the redundant configuration methods of the Modular Multi-level Converter (MMC)’s Sub-Module (SM), and topological structure, control and protection, fault analysis, etc. The necessity of this study is justifiable on the grounds of realities. Moreover, this paper introduces and deduces the Markov process and applies it to propose a reliability analysis model for the main wiring diagram of a HVDC transmission project. Finally, the calculation of the model is carried out by the program written in Matlab. By comparing the results with the statistical data of ABB, it testifies that the method proposed is suitable for the reliability analysis of VSC-HVDC system.
