中压保护测控装置分别安装于配电房10kV系统进线柜、出线柜、分段柜，每台中压保护测控装置采集对应开关柜的遥测数据和遥信数据，对开关具备电动控制功能，当母线或线路发生故障时检测故障并瞬时断开开关切除故障，具有以太网或RS485通信接口实现遥测、遥信、遥控功能；
配电物联网关、中压保护测控装置、框架断路器脱扣器、塑壳断路器智能模块通过通信电缆连接成通信网络；10kV系统和380V系统的母线电压、线路电流、开关状态、保护跳闸状态分别由中压保护测控装置、框架断路器脱扣器/塑壳断路器智能模块采集并上传到配电物联网关；
如图2所示，本实施例中，一座配电房的两段10kV中压I段母线、中压II段母线分列运行，将分段开关S1断开；中压I段母线由电源P1经进线L1供电，中压II段母线由电源P2经进线L2供电。两段380V低压I段母线、低压II段母线也分列运行，将开关S2断开；低压I段母线由受电线L5供电，低压II段母线由受电线L6供电。中压I段母线通过出线L3经变压器向受电线L5供电，中压II段母线通过出线L4经变压器向受电线L6供电，这是配电房供电系统的正常运行状态。
对于二次设备，在配电房中压系统的每个进线开关、每个出线开关、分段开关处各配置一台中压保护测控装置在本实施例中包括L1、L2、L3、L4、S1；在配电房低压系统的每个受电开关、每个馈线开关、母联开关处各配置一台智能脱扣器、智能模块在本实施例中，包括L5、L6、L7、L8、S2；所有中压保护测控装置、框架断路器智能脱扣器、塑壳断路器智能模块通过通信电缆连接到配电物联网关；
配电房供电系统正常运行时，配电物联网关每10秒更新中压和低压二次设备的遥测和遥信数据并保存。当中压充电条件，本实施例中，中压充电条件为：中压I段母线、中压II段母线均三相有电压，且DLL1、DLL2 在合位，且DLS1在跳位，满足15S后置中压充电完成标志。当低压充电条件，本实施例中的低压充电条件为：低压I段母线、低压II段母线均三相有电压，且DLL5、DLL6 在合位，且DLS2在跳位，满足15S后置低压充电完成标志。当遥测数据或遥信数据有突变时二次设备主动及时上送所有数据。当中压放电条件，本实施例中，中压放电条件为：DLS1在合位，或中压I段母线、中压II段母线均三相无压，或中压保护测控装置L1保护跳闸状态或手动跳闸状态为1，或中压保护测控装置L2保护跳闸状态或手动跳闸状态为1，或中压备用电源自动投入完成，满足瞬时完成放电，清中压充电完成标志；当低压放电条件，本实施例中，低压放电条件为：DLS2在合位,或低压I段母线、低压II段母线均三相无压，或框架断路器L5保护跳闸状态或手动跳闸状态为1，或框架断路器L6保护跳闸状态或手动跳闸状态为1，或低压备用电源自动投入完成，满足瞬时完成放电，清低压充电完成标志；
故障点F1发生短路故障，上级保护装置跳闸切断电源P1，中压I段母线、低压I段母线及关联的线路电压和电流全部下降为0，所带负荷全部失电，导致中压和低压二次设备的遥测数据发生突变，这时配电物联网关迅速更新接收到的遥测和遥信数据；配电物联网关对比故障发生前后的遥测、遥信数据，并分析关联的一次设备之间的拓扑关系，可以确定是由于开关DLL1以上线路故障导致本配电房失电，从而在中压充电完成标志为1时启动中压备用电源投入逻辑恢复供电：中压I段母线无压、线路L1无流，中压II段母线有压，则经延时跳DLL1，确认DLL1跳开后，合DLS1；
故障点F2发生短路故障，保护装置L3跳开断路器DLL3，低压I段母线及关联的线路电压和电流全部下降为0，所带负荷全部失电，导致相关低压二次设备的遥测数据发生突变，这时配电物联网关迅速更新接收到的遥测和遥信数据。配电物联网关对比故障发生前后的遥测、遥信数据，并分析关联的一次设备之间的拓扑关系，可以确定是由于开关DLL3与开关DLL5之间线路故障导致，从而在低压充电完成标志为1时启动低压备用电源投入逻辑恢复供电：低压I段母线无压、线路L5无流，低压II段母线有压，则经延时跳DLL5，确认DLL5跳开后，合DLS2；
故障点F3发生严重短路故障导致越级跳闸，即塑壳断路器L7、框架断路器L5分别跳开断路器DLL7、DLL5，低压I段母线及关联的线路电压和电流全部下降为0，所带负荷全部失电，导致相关低压二次设备的遥测数据发生突变，这时配电物联网关迅速更新接收到的遥测和遥信数据，配电物联网关对比故障发生前后的遥测、遥信数据，并分析关联的一次设备之间的拓扑关系，可以确定是由于开关DLL7以下线路故障导致，从而启动越级跳闸自动恢复供电逻辑：合DLL7，经延时再合DLL5，如果是永久性故障，则合DLL7后会再次跳开并且隔离故障，瞬时性故障就会重合成功，合DLL5后恢复非故障区域供电；
在每次故障发生后，配电物联网关将对其操作过的开关状态进行视频确认，即控制摄像头或巡检机器人获取视频数据，利用人工智能技术进行开关状态的二次确认。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换,凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
