Automatic Evaluation Method for Operating Status of Electric Energy Metering Devices Based on Fuzzy Hierarchy
To accurately determine the operating status of electric energy metering devices,a fuzzy analytic hierarchy process based automatic evaluation method for the operating status of electric energy metering devices is proposed.The DEMATEL method is applied to select automatic evaluation indicators for the operation status of electric energy metering devices and collect data corresponding to the indicators.The weight of the indicators is calculated and the evaluation value is gained by fuzzy comprehensive evaluation method.According to the principle of maximum membership,the operating status level is obtained.The results indicate that the electric energy metering devices No.1 and No.4 are in normal condition,and the No.2 and No.3 electric energy metering devices are in a state of attention,indicating that these two devices have some signs of failure,while the No.5 electric energy metering device is in an abnormal state,in which the electric energy metering device no longer functions properly and requires maintenance.Test results verify the effectiveness of the proposed method.
