| 摘要: |
| 提出基于模糊综合评判的直流输电系统检修时机选择方法。通过选择和改进电网充裕度评估指标，构建模糊综合评判体系，得到直流输电系统在正常运行与直流通道停运时电网风险水平的变化，对模糊结果集进行分值量化和评语总结。根据直流通道的检修判据得到直流系统停运的建议方案。以2011年南方电网某天的直流检修安排为例，结果表明，该方法可有效辨识日运行方式下直流输电系统的检修时机，获得适合停运的时间段。 |

| Abstract: |
| A method of HVDC system maintenance timing based on fuzzy comprehensive evaluation is proposed. A fuzzy comprehensive evaluation system is built by choosing and improving the power system adequacy evaluation index to obtain the difference of power system risk level between normal and outage operating modes of HVDC system for the further score quantification and comment summary of the fuzzy result set. The HVDC system outage proposal is achieved according to the HVDC channel maintenance criterion. As an example，a daily HVDC maintenance arrangement of China Southern Power Grid is made for a certain day in 2011，which shows that，the proposed method effectively identifies the maintenance timing of HVDC system in daily operating mode and sets suitable outage period. |
