【摘要】：完善的变电设备检修体系为提前发现设备缺陷、降低事故概率、保证电网安全运行起着至关重要的作用。变电设备状态检修制度已经在我们国内广泛开展,它不仅降低了供电企业的检修成本,提高了变电设备的维护率以及利用率,同时也解决了以往周期性预防性检修存在的变电设备过修和欠修问题。但由于历史原因,实际一线检修人员的检修思维模式还不能完全摆脱以往周期性预防性检修阶段对设备试验数据的分析方法,制定检修策略时往往只注重局部,存在一定的盲目性,缺乏完善的变电设备状态评估手段以及科学的检修策略。本文为了解决这一问题对变电设备状态检修策略进行了深入研究,以我们宁波电业局目前实际在开展的检修模式为基础,利用以往周期性预防试验积累的数据以及带电测试、在线监测技术,综合分析我们现场所能获得的设备状态信息量,制定出一套变电设备状态评价方法以及相应的状态检修策略。同时为了摆脱人工对大量设备状态信息数据的处理,提出了计算机辅助人工进行变电设备状态的评估,并进行了相应的变电设备状态评估与决策系统的开发。通过该系统实际在我们宁波电业局的应用,使我们检修人员实时掌握了辖区内变电设备基本运行健康状况,同时辅助生产技术人员对状态不良的变电设备进行检修策略的制定。为我们局更好、更科学的开展变电设备状态检修工作提供了很好的技术支撑。
[Abstract]:The perfect substation equipment maintenance system plays an important role in detecting equipment defects in advance, reducing accident probability and ensuring the safe operation of power grid. The condition maintenance system of substation equipment has been widely carried out in our country. It not only reduces the maintenance cost of power supply enterprises, but also improves the maintenance rate and utilization ratio of substation equipment. At the same time, it also solves the problems of overrepair and underrepair of substation equipment existing in the past periodic preventive maintenance, but due to historical reasons. The maintenance thinking mode of the actual front-line maintenance personnel can not completely get rid of the analysis method of the equipment test data in the past periodic preventive maintenance stage, and often only pay attention to the part when drawing up the maintenance strategy. There are some blindness, lack of perfect means of substation equipment status evaluation and scientific maintenance strategy. In order to solve this problem, this paper makes a deep research on the status maintenance strategy of substation equipment. Based on the maintenance mode that Ningbo Electric Power Bureau is carrying out at present, this paper makes use of the data accumulated in the past periodic preventive tests and live test, and on-line monitoring technology. Comprehensive analysis of the amount of equipment status information we can obtain on site. A set of condition evaluation method and corresponding condition maintenance strategy are worked out. Meanwhile, in order to get rid of manual processing of a large number of equipment state information data. This paper presents a computer-aided manual evaluation of the status of substation equipment, and develops a corresponding system for evaluating the status of substation equipment and developing a decision system. The system is applied in Ningbo Electric Power Bureau. So that our maintenance personnel in real time grasp the basic operating health of the substation equipment in the jurisdiction, while assisting production technicians to make maintenance strategy for the poor state of the transformer equipment, so as to better for our bureau. More scientific development of substation equipment condition maintenance work to provide a good technical support.
