The invention discloses a method for reliability assessment of a transformation equipment online monitoring device. The method comprises the steps of: obtaining a feature data set of a monitoring device to be assessed; marking invalid data in the feature data set; discriminating the feature data set by employing the criteria of various invalid data to obtain discrimination values corresponding tothe feature data set; respectively distributing different weight values for the discrimination values, summing the discrimination values to obtain the state value of the monitoring device; and comparing the state value with the tolerance to complete assessment for the monitoring device. The problem is solved that current transformation equipment online monitoring devices are different in quality so that electric power enterprises cannot comprehensively and systematically master the running condition of the devices.
Description
technical field [0001] The application relates to the field of operation management of power transmission and transformation equipment, in particular to a method for evaluating the reliability of an online monitoring device for power transformation equipment, and at the same time relates to a reliability evaluation device for an online monitoring device. Background technique [0002] For the continuous improvement of the level of electrification, the continuous development of on-line monitoring devices and sensor technology for substation equipment puts forward higher requirements for the reliability management of on-line monitoring devices. With the application of advanced mathematical theories and modeling methods, great progress has been made in research directions such as arranging maintenance plans based on online monitoring equipment data. However, due to the limitations of monitoring device operation and data quality, these studies often use ideal values for some li...
