Problems solved by technology

[0004] In the past, power meters in the industry mainly measured basic data such as voltage and current, and could not effectively monitor power quality data such as three-phase unbalance, system harmonic analysis, voltage fluctuation and flicker in the power system
Therefore, it is impossible to make a complete analysis of the system situation in the power grid.

Abstract

The invention relates to an electric energy monitoring front end data acquisition device which comprises a power module, a data acquisition module, an operational amplifier, an A / D conversion chip, a control module, an Ethernet controller and a high-speed communication bus. The data acquisition module collects external electric energy signals, one line of output signals of the data acquisition module is conditioned by the operational amplifier in a signal mode and then is transmitted to the A / D conversion chip, after active power filter processing is conducted on another line of the output signals, the another line of the output signals is directly transmitted to the A / D conversion chip, the A / D conversion chip converts the received signals into digital signals, then the digital signals are transmitted to the control module, the control module conducts packing processing on received data, a data package is transmitted to the Ethernet controller, and finally the data package is issued to a control device through the high-speed communication bus. Compared with the prior art, the electric energy monitoring front end data acquisition device has the advantages of being high in data monitoring precision, strong in adaptive capacity, powerful in function, low in power dissipation, convenient to mount, reliable in data transmission, high in communication speed, capable of achieving high-speed networking and the like.

Description

technical field [0001] The invention relates to an electric energy data acquisition, signal processing and data communication device, in particular to an electric energy monitoring front-end data acquisition device. Background technique [0002] Power Quality, strictly speaking, the main indicators to measure power quality are voltage, frequency and waveform. Generally speaking, it refers to high-quality power supply, including voltage quality, current quality, power supply quality and power quality. It can be defined as: the deviation of voltage, current or frequency that causes electrical equipment to fail or fail to work normally, including frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase unbalance, temporary or transient overvoltage, Waveform distortion (harmonic), voltage sag, voltage interruption, voltage swell, and power supply continuity, etc. [0003] With the development of the national economy and the improvement of people's l...
