发布时间：2018-07-13 12:02
【摘要】：随着微机保护的全面使用,并且慢慢向数字化智能化方向发展,常规的定期检验制度对设备进行维护已经不合适宜,因此开展保护设备的状态检修已势在必行。 本文论述了对电气设备进行状态检修必要性及现状,研究了对继电保护进行状态检修的可行性,提出了继电保护状态检修的硬件组成及评价状态量的获取方法。给出了继电保护状态检修的流程,从继电保护状态检修设备状态信息的采集出发,分析了继电保护状态检修的数据结构,研究了故障诊断技术、计算机辅助决策系统及风险评估与检修决策系统在继电保护状态检修中的作用。针对继电保护检修管理当前的模式,就继电保护状态检修管理提出实施建议。对于指导继电保护设备状态检工作,保证设备安全可靠运行,具有重要的理论意义和工程实用价值。
[Abstract]:With the full use of microcomputer protection and the development of digital intelligence, the routine periodic inspection system is not suitable for the maintenance of the equipment, so it is imperative to carry out the condition maintenance of the protection equipment. This paper discusses the necessity and present situation of condition based maintenance for electrical equipment, studies the feasibility of condition based maintenance for relay protection, and puts forward the hardware composition of condition maintenance of relay protection and the method of obtaining the evaluation state quantity. The flow chart of condition maintenance for relay protection is given. The data structure of condition maintenance of relay protection is analyzed, and the technology of fault diagnosis is studied based on the collection of state information of equipment for condition maintenance of relay protection. The role of computer aided decision system and risk assessment and maintenance decision system in condition maintenance of relay protection. In view of the current mode of maintenance management of relay protection, some suggestions are put forward for the management of condition maintenance of relay protection. It is of great theoretical significance and practical value for guiding the state inspection of relay protection equipment and ensuring the safe and reliable operation of the equipment.
