Embodiment
[0026] In the present invention, the specific implementation mode is described by taking the battery detection data collected in a certain time as an example.
[0027] In power metering equipment, lithium thionyl chloride batteries are generally used as power supply and timing batteries for power metering equipment. Lithium thionyl chloride batteries are the battery with the highest battery voltage (nominal 6V) and specific energy in the actual application battery series. . Its specific energy can reach 590W.h / kg and 1100W.h / L. This program selects the ER14250 battery among the lithium thionyl chloride batteries. The battery size conforms to the IEC standard lithium thionyl chloride battery. Good characteristics, long storage life, high specific energy, good safety performance and so on.
[0028] The Thevenin model is a commonly used battery model. Its principle is based on the Rint model, which is to connect a group of RC parallel networks in series on its main road, thereb...

The invention provides a multi-dimensional detection data normalization method of key components for electric power metering equipment. The method specifically comprises the following steps: constructing a formalized model of the key components of the electric power metering equipment according to physical characteristics, and defining characteristic values; analyzing multi-dimensional detection data, and selecting a normalized fitting method of influence factors-component characteristic values; establishing a data fitting model of influence factors-component characteristic values by using normalization modes such as a neural network; verifying the normalized data fitting model by using other detection data; and realizing normalization of the detection data of the electric power metering equipment by applying the formalized model and the data fitting model of the component. Technical support is provided for normalization of the multi-dimensional detection data of the component.
Description
technical field [0001] The invention belongs to the field of electric energy metering, in particular to a method for normalizing multi-dimensional detection data of key components used in electric metering equipment. Background technique [0002] Power metering equipment is one of the important basic equipment for smart grid construction. The reliability and service life of power metering equipment components directly determine the overall quality of the equipment. The indicators and detection methods are different, which leads to inconsistencies in the performance evaluation standards of key components. This inconsistency will lead to the incompatibility of different test results, and there is no unified test data evaluation standard on the market. It is shown that there is a need for a bridge that can connect the detection data under different test methods and conditions, standardize and standardize the detection data, and finally achieve the purpose of improving utilizati...
