Problems solved by technology

Due to the use of dedicated line communication, the wiring is complicated and the cost is increased. If the timing time is not corrected through the line communication, due to the traditional timing error, after several hours of operation, the accumulated timing error will make the system control action inconsistent, which may cause the system to collapse. In some occasions where the design is changed frequently and the amount of wiring engineering is large, the product application is limited

Abstract

The invention relates to a plant power load information acquisition system, which is composed of multiple electric quantity monitoring instruments and a main controller. Each distribution line is provided with one electric quantity monitoring instrument; under the control of synchronization time, each electric quantity monitoring instrument can realize synchronous three-phase voltage and current sampling of each distribution line at a certain time point; sampled signals are subjected to conditioning transformation; and each electric quantity monitoring instrument outputs acquired electric quantity data and the data are transmitted to the main controller for processing.

Description

(1) Technical field: [0001] The invention relates to a factory power load information collection system, which is composed of a plurality of power monitoring instruments and a main controller. Each power distribution line is equipped with a power monitoring instrument. Under the control of synchronous time, each power monitoring instrument can realize synchronous sampling of the three-phase voltage and current of each power distribution line at a certain time point, and adjust and transform the sampling signal. Each power monitoring instrument outputs the collected power data and sends them to the main controller for processing. (two) background technology: [0002] In the control system that is powered by the power grid, each electronic device or module communicates through a dedicated line to correct the timing time of each electronic device or electronic module to achieve the purpose of synchronous operation. Due to the use of dedicated line communication, the wiring is ...
