【摘要】：随着智能变电站技术应用的推进,变电站一次设备具备状态监测功能成为一种技术发展趋势,随着全寿命周期管理模式的推进,传统的一次设备定期检修模式正在逐步演变为状态检修。而在二次设备方面,由于保护系统涵盖模拟量输入、保护装置动作及分合闸输出环节,而微机保护仅能自检约80%环节,因此,长期以来保护系统依旧采取了传统的定期检修模式。2007年国家电网公司开始组织开展输变电一次设备的状态检修工作,形成了《输变电设备状态检修的验收细则》,一次设备检修管理体制将逐步实现计划检修向状态检修的转化。在一次设备状态检修的基础上,上海电力公司继保处认真汲取变电站一次设备状态检修的经验,研究继电保护设备结构和技术特性,建立了以状态评价为基础、标准化作业为保障,较为完整的继电保护设备状态检修体系。在本项目中,首先对继保状态检修的评价导则进行了研究,根据上海的设备特点制定了符合上海实际情况的评价导则;接着对继保状态检修系统进行了需求分析,通过现状分析及功能需求分析,最后编制了继保状态检修系统的需求分析;在需求分析的基础上,对继保状态检修系统进行了概要设计、详细设计;最后通过编程语言实现了继保状态检修系统。系统开发完成后,通过人工测试与系统测试相结合的方式对系统进行了详细的测试。目前该系统已经在上海电力公司及下属供电公司展开了实际应用,取得了一致好评。
[Abstract]:With the advance of intelligent substation technology application, it has become a trend of technology development that the primary equipment of substation has the function of condition monitoring, and with the development of life-cycle management mode, The traditional periodic maintenance mode of primary equipment is gradually evolving into condition based maintenance. In the secondary equipment, because the protection system covers analog input, protection device action and closing output links, and microcomputer protection can only self-check about 80% of the links, so, For a long time, the protection system has still adopted the traditional regular maintenance mode. In 2007, the State Grid Corporation began to organize and carry out the condition maintenance work of the power transmission and transformation primary equipment. The acceptance rules for condition based maintenance of transmission and transformation equipment have been formed, and the management system of primary equipment maintenance will gradually realize the transformation from planned maintenance to condition based maintenance. On the basis of the condition maintenance of the primary equipment, Shanghai Electric Power Company has carefully absorbed the experience of the condition maintenance of the primary equipment in the substation, studied the structure and technical characteristics of the relay protection equipment, and established the basis of the condition evaluation. Standardized operation as a guarantee, a more complete relay protection equipment condition maintenance system. In this project, first of all, the evaluation guidelines of reinsurance condition maintenance are studied, and according to the characteristics of equipment in Shanghai, the evaluation guidelines are formulated according to the actual conditions in Shanghai, and then the requirements of the condition maintenance system are analyzed. Through the current situation analysis and functional requirement analysis, the requirement analysis of the condition based maintenance system is worked out, and on the basis of the requirement analysis, the general design and detailed design of the condition based maintenance system are designed. At last, the condition maintenance system is realized by programming language. After the development of the system, the system is tested in detail by the combination of manual test and system test. At present, the system has been applied in Shanghai Electric Power Company and its subordinate power supply company.
