The invention discloses a method and device for carrying out state evaluation on an electric energy meter field calibration instrument. The method comprises the steps of: acquiring preset parameters;carrying out index decomposition on a state evaluation aspect of the electric energy meter field calibration instrument, and determining quantified state items which can be used for evaluating a stateof the electric energy meter field calibration instrument; according to the preset parameters and an electric energy meter field calibration instrument state evaluation model, determining weight values and quantified values of the quantified state items, and calculating a score result of the electric energy meter field calibration instrument; and according to the score result and a preset early warning threshold, carrying out early warning on the electric energy meter field calibration instrument. According to the method, state evaluation is introduced into the electric energy meter field calibration instrument, and by carrying out state evaluation on a field state of the electric energy meter field calibration instrument, problems of the electric energy meter field calibration instrumentare timely found and treated, so as to promote efficiency of electric energy meter field detection, ensure accuracy of electric energy meter field detection and reduce economic loss caused by inaccuracy of the electric energy meter field calibration instrument.
Description
technical field [0001] The invention relates to the professional field of electric energy metering, and more specifically, to a method and device for evaluating the state of an electric energy performance calibrator Background technique [0002] The electric energy performance calibrator is a device for on-site detection of electric energy meters installed in power grid enterprises, power generation enterprises, and power consumption enterprises for trade settlement and internal assessment. [0003] The current power industry standard DL / T448 "Technical Management Regulations for Electric Energy Metering Devices" requires regular on-site inspections of installed electric energy meters to ensure the accuracy of on-site operating electric energy meters. On-site inspection of electric energy meters within the scope of management, due to the wide distribution of electric energy meters and remote locations, bumps and losses will inevitably occur when the electric energy meter is ...
