【摘要】：继电保护压板位置一般与一次设备运行方式相关,在一次设备运行方式改变时,有时需要改变压板的位置进行匹配。实际运行操作中因压板位置投退错误,已导致多起事故发生。为了避免保护压板出现漏投、误投现象,从搜索一次元件状态、运行方式的角度出发,在采集压板位置信息基础上,提出了一种压板位置与一次元件运行方式匹配状态的智能校核方法。根据一次元件的运行状态及相应的压板整定规则,生成一次元件压板位置关联规则库,利用变电站开关状态信息在变电站倒闸操作后自动识别一次元件状态,与一次元件压板规则库进行比较,当出现不一致时给出报警提示信号,实现了压板位置的智能校核。通过对实际工程中变压器运行转检修操作任务的分析,验证了所提方法的有效性。
[Abstract]:The position of relay protection pressure plate is usually related to the operation mode of primary equipment. When the operation mode of primary equipment is changed, it is sometimes necessary to change the position of the press plate to match. In the actual operation, many accidents have occurred because of the error in the position of the press plate. In order to avoid the phenomenon of leakage and misthrow of the protection plate, from the point of view of searching the state of the primary element and running mode, on the basis of collecting the position information of the press plate, This paper presents an intelligent checking method for matching the position of the pressing plate with the running mode of the primary component. According to the running state of the primary element and the corresponding setting rules of the press plate, the position association rule base of the primary component is generated, and the state of the primary element is automatically identified by using the information of the switching state of the substation after the switching operation of the substation. Compared with the primary pressure plate rule base, the alarm signal is given when there is inconsistency, and the intelligent check of the position of the press plate is realized. The effectiveness of the proposed method is verified by analyzing the operation tasks of transformer operation and maintenance in practical engineering.
