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。
The position of relay pressed boards is generally associated with primary device operating mode.When the primary device operating mode changes,sometimes it’s necessary to accordingly change the position of pressed board.Indeed,the misoperation of pressed board has led to many accidents.To avoid this failing,from the perspective of primary device state and operation mode,an intelligent verification method for relay protection pressed board is proposed on the basis of collecting the position information of pressed boards.Through the relationship between relay protection and automatic devices pressed board setting rules and state of primary devices,aprimary device-pressed board position rulebase is generated.When substation switching operation occurs,the device will automatically recognize primary device state and compare the state with the information in the rulebase,and it will give alarm signal when the comparison does not match.A real test of transformer operational processes is carried out,and the result shows that the intelligent verification method is effective.
