中压开关柜健康度评价方法、装置及系统
摘要：
本申请涉及一种中压开关柜健康度评价方法、装置及系统，其中，所述方法包括以下步骤：获取对应中压开关柜的监测数据；监测数据包括至少一个开关柜监测子数据；将各开关柜监测子数据进行归一化处理，得到各对应开关柜监测子数据的归一化数值；基于各开关柜监测子数据的重要程度，得到各对应开关柜监测子数据的变权重值；对各归一化数值和各变权重值进行信息融合处理，得到中压开关柜的健康度评估值；基于预设的健康度划分区间处理健康度评估值，得到相应的开关柜健康度。本申请能够大量减少现场的巡维工作量，更准确且及时掌握开关柜的在线运行状态，确定其设备健康等级，提高电网设备可靠性。
摘要（英）：

The invention relates to a medium-voltage switch cabinet health degree evaluation method, device and system, wherein the method comprises the following steps of obtaining the monitoring data of a corresponding medium-voltage switch cabinet, wherein the monitoring data comprises at least one switch cabinet monitoring sub-data; normalizing the switch cabinet monitoring sub-data to obtain a normalized numerical value of each corresponding switch cabinet monitoring sub-data; obtaining a variable weight value of each corresponding switch cabinet monitoring sub-data based on the importance degree ofeach switch cabinet monitoring sub-data; performing information fusion processing on each normalized numerical value and each variable weight value to obtain a health degree evaluation value of the medium-voltage switch cabinet; and processing the health degree evaluation value based on a preset health degree division interval to obtain a corresponding switch cabinet health degree. According to the present invention, the on-site inspection and maintenance workload can be greatly reduced, the on-line operation state of the switch cabinet can be more accurately and timely grasped, the health level of the switch cabinet is determined, and the reliability of the power grid equipment is improved.
