一种基于状态监测数据确定电力设备的运行状态的方法及系统
摘要：
本发明公开了一种基于状态监测数据确定电力设备的运行状态的方法及系统，包括：对电力设备的运行状况进行监测，以获取所述电力设备的至少一项状态监测数据；根据所述电力设备对应的状态监测数据按照预设的评分规则，确定所述电力设备的每项状态监测数据对应的评分；利用所述电力设备的每项状态监测数据对应的评分，根据预设的状态隶属函数，确定每项状态监测数据在每种健康状态下的概率值；基于D-S证据理论，根据每项状态监测数据在每种健康状态下的概率值进行概率融合，以获取所述电力设备的每种健康状态对应的概率融合结果；根据所述电力设备的每种健康状态对应的概率融合结果确定所述电力设备的运行状态。
摘要（英）：

The invention discloses a method and system for determining the operation state of power equipment based on state monitoring data, and the method comprises the steps: monitoring the operation state ofthe power equipment, so as to obtain at least one piece of state monitoring data of the power equipment; determining a score corresponding to each piece of state monitoring data of the power equipment according to the state monitoring data corresponding to the power equipment and a preset scoring rule; determining a probability value of each piece of state monitoring data in each health state according to a preset state membership function by utilizing the score corresponding to each piece of state monitoring data of the power equipment; based on a D-S evidence theory, performing probabilityfusion according to the probability value of each piece of state monitoring data in each health state to obtain a probability fusion result corresponding to each health state of the power equipment; and determining the operation state of the power equipment according to the probability fusion result corresponding to each health state of the power equipment.
