发布时间：2018-08-11 17:12
【摘要】：随着电网规模的不断扩大,供电公司的管辖设备大幅度增加,试验装备不足,检修人员紧缺问题明显,以往以周期性停电试验为主的状态检修已显出局限性。同时,在智能电网建设条件下,对供电可靠性的要求也日益提高,但随着大量的新型元件和设备的接入,进一步提高电网的运行风险,对电网的稳定性及可靠性带来了挑战。因此原有状态检修模式已经不能适应保定地区电网发展的要求,探索应用在线监测代替停电例行试验,通过设备安全分级对不同等级设备采取不同的状态检修策略,解决目前设备运维检修过程中的困难具有重要的意义。本文首先阐述了传统电网监测技术的不足,分析了智能电网下的在线监测技术,研究电力设备关键状态量的替代方法;其次,分析了状态检修和在线监测的关系,论证了差异化巡视和检修的可行性,设计了生产指挥管控平台,提出了针对保定公司的差异化状态检修策略,并通过生产指挥管控平台的有效运转,保证检修策略措施的高效实施;最后,结合中国电谷智能电网实际,讨论了基于在线监测技术的状态检修策略的实际应用情况。本文的研究,为电力企业检修工作提出了新的思路和管理方法,减少了不必要的设备巡视和检修,有助于提高设备运维管理水平,为企业稳定发展做出了贡献。
[Abstract]:With the continuous expansion of the power network scale, the power supply company's jurisdiction equipment increases by a large margin, the test equipment is insufficient, the maintenance personnel is in short supply problem obviously, the condition maintenance which used to be mainly based on the periodic blackout test has shown the limitation in the past. At the same time, under the condition of smart grid construction, the demand for power supply reliability is also increasing day by day. However, with the access of a large number of new components and equipment, the operation risk of power network is further increased, which brings challenges to the stability and reliability of power grid. Therefore, the original condition maintenance mode can no longer meet the requirements of the development of Baoding power network. This paper explores the application of on-line monitoring instead of the routine test of power outage, and adopts different stateful maintenance strategies for different grades of equipment through the safety classification of equipment. It is of great significance to solve the difficulties in the process of equipment maintenance and repair. In this paper, the shortcomings of traditional power network monitoring technology are discussed, the on-line monitoring technology under smart grid is analyzed, and the substitution method of critical state quantity of power equipment is studied. Secondly, the relationship between condition-based maintenance and on-line monitoring is analyzed. The feasibility of differential inspection and maintenance is demonstrated, the production command and control platform is designed, the strategy of differentiated condition maintenance for Baoding Company is put forward, and the effective operation of production command and control platform is put forward. Finally, the application of condition based maintenance strategy based on on-line monitoring technology is discussed. The research in this paper puts forward new ideas and management methods for the maintenance of electric power enterprises, reduces the unnecessary inspection and repair of equipment, helps to improve the management level of equipment operation and maintenance, and contributes to the steady development of enterprises.
