The utility model relates to a based on the design of least spuares curve fitting's change electric energy meter electric quantity with electricity and remedy optimization metering device is simple reliable, man -machine interface is friendly, change the electric energy meter electric quantity based on least spuares curve fitting's electrification simultaneously and remedy optimization method and improved measurement accuracy as a result, guaranteed the economic interests of purchasing the sale of electricity both sides.
Description
Technical field
The utility model belongs to Electric Energy Metering Technology, and the live replacement of electric energy meter electric quantity compensating especially based on least square curve fit optimizes measuring apparatus structure technology.
Background technology
For ensureing that not affecting normal electricity produces and run, Electric Energy Tariff Point Metering Device renovates and adopts the online mode changed to carry out, so just relate to dismounting gate energy meter and can produce electric quantity loss during this period of time, corresponding compensation must be carried out, to ensure the economic interests of run unit by electric quantity loss during swap table.
In Source of Gateway Meter replacing, we adopt the power before changing table to be multiplied by Time Calculation loss electricity at the scene, but have comparatively big error when Renewal process finds that load variations is larger, are not optimal electricity compensation way.So a lot of Electricity customers is not approved the electricity of remedying calculated, thus have impact on electric power enterprise and reasonable, the just electricity consumption transaction of Electricity customers.
Summary of the invention
The utility model object is to provide a kind of live replacement of electric energy meter electric quantity compensating to optimize measuring apparatus, the metering accuracy that in transforming under can improving Source of Gateway Meter online mode, electric quantity loss compensates, and conscientiously ensures the economic interests purchasing sale of electricity both sides.
For realizing above technical purpose, the utility model proposes a kind of live replacement of electric energy meter electric quantity compensating and optimizing measuring apparatus technical scheme.
The utility model is that a kind of live replacement of electric energy meter electric quantity compensating optimizes measuring apparatus, and this system comprises: power switch unit, the electricity compensation deals unit based on least square curve fit, communication unit, electric energy meter on-site calibrator access signal element, combined connection box wiring units.Wherein, described power switch unit is for accessing 220V AC power, and described power supply unit is given and powered and can show on-site calibrator access signal element power based on the electricity compensation deals unit of least square curve fit, communication unit unit.The described electricity compensation deals unit based on least square curve fit is connected with communication unit, described communication unit and electric energy meter on-site calibrator access signal element and are connected, and described combined connection box wiring units is together with field electric energy table voltage and current metering end sub-connection.
The utility model is the instantaneous power dis-crete sample values utilizing three-phase electric energy meter on-site calibrator measurement device, then connected by communication unit, transfer data to the electricity compensation deals unit counting loss electricity based on least square curve fit and show.
The beneficial effects of the utility model and advantage as follows: can Real-time Collection power signal, utilize least square curve fit power to carry out electricity calculating, and then guarantee to change the accuracy of losing electric quantity metering in electric energy meter process.
Accompanying drawing explanation
Fig. 1 is that a kind of live replacement of electric energy meter electric quantity compensating optimizes measuring apparatus schematic diagram;
Below in conjunction with the drawings and specific embodiments, embodiment of the present utility model is further described.
Embodiment
As shown in Figure 1, a kind of live replacement of electric energy meter electric quantity compensating optimizes measuring apparatus, comprising: power switch unit, the electricity compensation deals unit based on least square curve fit, communication unit, electric energy meter on-site calibrator access signal element, combined connection box wiring units.Wherein, described power switch unit is for accessing 220V AC power, and described power supply unit is given and powered and can show on-site calibrator access signal element power based on the electricity compensation deals unit of least square curve fit, communication unit unit.The described electricity compensation deals unit based on least square curve fit is connected with communication unit, described communication unit and electric energy meter on-site calibrator access signal element and are connected, and described combined connection box wiring units is together with field electric energy table voltage and current metering end sub-connection.
Described in the utility modelly be characterised in that the instantaneous power dis-crete sample values utilizing three-phase electric energy meter on-site calibrator measurement device, then connected by communication unit, transfer data to the electricity compensation deals unit counting loss electricity based on least square curve fit and show.
Respectively each step is described as follows below:
Comprise the following steps: first, before carrying out changing table handling, by three-phase electric energy meter on-site calibrator device voltage link and be connected to loop, electric current wiring serial connection to loop.When carrying out changing table handling, reliable short circuit is changed electric energy meter secondary current testing terminal, and judge whether reliable short circuit by clamp reometer measurement current value size, then connected by communication unit, the power data discrete point that three-phase electric energy meter on-site calibrator is measured is transferred to electricity compensation deals unit, and last counting loss electricity also shows.
A kind of live replacement of electric energy meter electric quantity compensating of the utility model optimization method improves metric results accuracy, ensure that the economic interests purchasing sale of electricity both sides.
