Research on Detection Technology of Customer Side Power Failure Status in Power Consumption Information Acquisition System

For the needs of detecting and uploading of power failure status in the power consumption information acquisition system under the condition of field installation and cost constraints,the super-capacitor is used as the backup power supply component of the watt hour meter to ensure the backup power supply time of 30 s.The customer side power failure status is judged indirectly by the state of the working power supply of the watt hour meter,and the correctness of the power failure state detection is improved by testing the plug-in status of the communication board.High speed power line carrier(PLC)and ZigBee wireless sensor network(WSN)are used to upload power failure status in order to improve the success rate of this status uploading.After the completion of the project design,the functions are tested and verified in the laboratory and user site,which prove the effectiveness of the proposed solution.
