摘　　要：状态检修是超高压输电线路检修策略的发展方向,准确对线路状态进行量化评估是状态检修的基础工作。目前超高压输电线路状态量化评估方法较少,已有的方法多为定性评价,也有文献提出了对电气设备状态信息进行评分并加权处理的方法,但评分方法比较简单且缺乏客观依据。结合上海市电力公司正在开展的超高压输电线路状态检修工作,提出了一种综合考虑输电线路状态信息,将线路状态信息与模糊综合评价相结合的超高压输电线路量化评估方法和步骤。实例分析表明了该方法的有效性和实用性。Status maintenance is the developing trend of the UHV transmission line maintenance strategy. And accurate status evaluation is the basis of maintenance. Currently most methods are from qualitative perspective instead of quantitative perspective. Some researches proposed weighted processing method to the status information of the equipment, But the approach is too simple and short of evidence. Based on the status maintenance work of Shanghai Electric Power Company, a new approach is developed, which combined fuzzy overall assessment with status information of the transmission lines. Case studies show that the method is effective and practical.
