Abstract

The present invention discloses a signal noise processing device during the electrical parameter metering process. The device comprises a waveform processing module, a metering operation module and a noise calculation module, wherein the above modules are electrically connected with one another. The waveform processing module is used for sampling an analog signal, converting the analog signal into a first digital signal and respectively outputting the first digital signal to the metering operation module and the noise calculation module. The noise calculation module is used for extracting a noise component from the first digital signal, adopting the noise component as a second digital signal and outputting the second digital signal to the metering operation module. The metering operation module is used for calculating the active power according to the first digital signal. The metering operation module is further used for calculating the average value of the active power and the second digital signal, so that the noise component in the average value of the active power is reduced. Based on the signal noise processing device, the extraction and the compensation for the key noise component of a small signal can be realized. The metering performance of the small signal is improved.

Description

technical field [0001] The invention relates to a signal noise processing device in the electric parameter measurement process, in particular to a noise estimation and compensation device in the small signal electric parameter measurement process. Background technique [0002] With the rapid development and popularization of grid intelligence, electricity metering at smart grid terminals has also put forward higher and higher requirements. In addition to the continuously enhanced communication, information processing and rich application capabilities, as its basic function, intelligent electrical parameter metering The primary impact is the substantial improvement of measurement accuracy or performance. For example, achieving a measurement accuracy of 1 / 10000 within a signal dynamic range of 1 / 10,000 has become a reality, and this has become a focus of many manufacturers. The improvement of metering performance is a systematic project, spanning analog circuits, digital circu...
