摘要(Abstract)：

为保证特高压直流输电的跨区能源调配的送电能力、不断提高能量可用率,采用故障分析、建模分析、现场试验等方法研究特高压换流站设备检修的若干关键问题。指出特高压直流输电系统设备数量多,油气绝缘单元多,适合采用在线油色谱、在线红外测温、SF6在线监测等成熟技术,逐步过渡到状态检修。以直流输电能量可用率指标为分析目标,研究分析特高压换流站检修工期安排问题,提出采用工期优化建议。特别分析共用接地极直流系统的接地极线路检修工期及安全措施布置问题。以奉贤换流站现场试验为基础,分析换流变压器套管、并联式避雷器等设备的预试方法,提出不解引开展高压预试的方法,分析比较与常规试验方法间的试验结果偏差。研究结果对提升特高压换流站设备检修工作水平有重要参考意义。
