【摘要】：随着电力系统容量的增大和电网规模的扩大,变电站作为电力能源变送及分配的枢纽载体,其设备故障对系统安全运行的影响越来越大,如果处理不好,甚至会引起整个系统的崩溃,给生产和生活造成巨大的影响。变电站设备在线监测技术的研究及应用,可以实现可靠、有效的设备运行状态监测目标,保障设备的安全运行,为电网安全、可靠运行打下坚实基础。此外,随着我国电力改革的逐步实施,通过对变电站设备进行状态监测及故障诊断,改传统的计划周期性检修为状态检修,从而降低电力企业的生产成本,已经成为企业降本增效的重要途径。本文基于在线监测技术现状,重点介绍了变电站内变压器、GIS、避雷器、断路器等设备的在线监测技术原理,研究了变电站主要设备在线监测系统分层结构的特点、架构体系、通讯标准、高级应用等。结合宁波电业局在线监测的安装、运行情况,通过对在线监测产品以及主流生产厂家的调研,对装置原理、技术特征和实际应用情况进行了比较分析,为产品选型、监测项目配置等提供重要的决策数据,从而对变电站设备在线监测项目进行技术约束,选择运行可靠、技术先进的在线监测装置设备。论文最后对目前智能变电站采用在线监测系统后的优势和投资因素进行了分析计算,并对设备状态监测系统进行技术经济举例,以此说明在线监测的合理使用的重要意义。
[Abstract]:With the increase of power system capacity and the expansion of power network scale, substation, as the hub carrier of power energy transmission and distribution, has more and more influence on the safe operation of power system. It can even lead to the collapse of the entire system, which has a huge impact on production and life. The research and application of on-line monitoring technology of substation equipment can realize reliable and effective monitoring target of equipment running condition, guarantee the safe operation of equipment, and lay a solid foundation for the safe and reliable operation of power grid. In addition, with the gradual implementation of the electric power reform in our country, through the condition monitoring and fault diagnosis of substation equipment, the traditional scheduled periodic maintenance is changed into the condition based maintenance, thus reducing the production cost of the electric power enterprise. Has become an important way to reduce the cost and increase efficiency. Based on the present situation of on-line monitoring technology, this paper mainly introduces the principle of on-line monitoring technology for transformer, arrester, circuit breaker and so on in substation, and studies the characteristics and architecture of on-line monitoring system of main equipment in substation. Communication standards, advanced applications, etc. Combined with the installation and operation of on-line monitoring of Ningbo Electric Power Bureau, through the investigation of on-line monitoring products and mainstream manufacturers, the principle, technical characteristics and practical application of the device are compared and analyzed, so as to select the products. Monitoring project configuration provides important decision data, so as to carry out technical constraints on substation equipment on-line monitoring project, and select reliable and technologically advanced on-line monitoring device equipment. At last, the paper analyzes and calculates the advantages and investment factors of the intelligent substation after adopting the on-line monitoring system, and gives a technical and economic example of the equipment condition monitoring system, which illustrates the importance of the rational use of the on-line monitoring system.
