所述开关设备变位时，所述开关设备所属间隔处于告警抑制状态；
所述开关设备变位时，所述开关设备所属厂站处于告警抑制状态；
所述开关设备变位时，通过电网拓扑搜索，发现所述开关设备相连刀闸都处于分的状态，且在变位时间前预设时间范围内，不存在所述开关设备的操作记录。其中，所述变位时间前预设时间可依据实际情况进行设定。
步骤2：识别所述开关设备的变位原因是否为误动变位，如果不是，执行步骤3；如果是，标识开关设备的变位原因为误动变位。
这里，在实际实施时，当确定开关设备的变位原因不是检修变位时，依据设置的变位原因的优先级进一步判断是否为误动变位，包括：
获取在预设的误动判断周期内所述开关设备的变位次数；
判断在所述误动判断周期内，所述开关设备的变位次数是否超过预设的变位次数限值；
所述开关设备的变位次数超过预设的变位次数限值时，识别所述开关 设备的变位原因为误动变位。
这里，预设的误动判断周期可以依据实际情况进行设定，但需要小于人工远方操作的最小时间间隔。其中，人工远方操作即人工远方控制开关设备，即通常所说的遥控。而人工远方操作的最小时间间隔指的是人工开始遥控开关设备到开关设备变位所需的时间，一般可设置为1分钟。对误动判断周期的判断采用滚动时间轴的方式。
预设的变位次数限值可依据实际需要进行设定，如1分钟之内不可能实现3次人工远方操作，也就是不可能有3次变位，因此，可设定变位次数限值为3。
步骤3：识别所述开关设备的变位原因是否为事故变位，如果不是，执行步骤4；如果是，标识开关设备的变位原因为事故变位。
这里，首先对事故变位进行解释：异常的开关设备变位会导致用户停电、人员伤亡以及更大的损失，称之为事故，这样的开关变位称为事故变位或事故跳闸，可以理解为开关变位导致事故。
在实际实施时，本步骤可包括：
基于所述分析结果确定存在以下情景至少之一时，识别所述开关设备的变位原因为事故变位：
所述开关设备所属间隔内事故总信号动作时间前后预设时间范围内，所述开关设备发生分闸变位；
所述开关设备所属间隔内事故信号动作时间前后预设时间范围内，所述开关设备发生分闸变位；
所述开关设备所属厂站内事故总信号动作时间前后预设时间范围内，开关设备发生分闸变位；
所述开关设备变位后预设时间内，且所述开关设备所属间隔重合闸信号发生动作后的预设时间范围内，所述开关设备发生合闸变位，之后所述 开关设备在预设时间内处于合闸状态；
所述开关设备变位后预设时间内，且所述开关设备所属间隔重合闸信号发生动作后的预设时间范围内，所述开关设备发生合闸变位，之后预设时间内，所述开关设备又发生分闸变位；
所述开关设备分闸变位时，在所述开关设备变位前预设时间范围内存在所述开关设备的操作记录，且最近一次操作记录的操作目标状态为合。
其中，事故信号，即电网故障时发出的信号，如跳闸，保护出口、母差保护等；
事故总信号，即是电网故障时多个信号合成出的信号，该信号由变电站侧合成。
信号动作时间，即是对应信号动作发生的时间。
步骤4：识别所述开关设备的变位原因是否为远方操作变位，如果不是，执行步骤5；如果是，标识开关设备的变位原因为远方操作变位。
这里，在实际实施时，本步骤可包括：
基于所述分析结果确定存在以下情景至少之一时，识别所述开关设备的变位原因为远方操作变位：
所述开关设备变位时，变位时间前预设时间范围内存在所述开关设备的远方操作记录及变位开关操作记录，且所述变位开关操作的目标状态与所述开关设备的变位状态一致；
其中，所述远方操作记录包括：单点遥控、序列控制、群控、批量负荷控制以及程序化控制；
所述开关设备变位时，变位时间前预设时间范围内存在变位开关自动控制记录，且所述控制的目标状态与所述开关设备的变位状态一致。
这里，单点遥控即仅对一个开关设备进行控制；序列控制即同时对一组开关设备进行控制。
步骤5：识别所述开关设备的变位原因为现场操作变位，并标识开关设备的变位原因为现场操作变位。
