Abstract

The invention discloses a data processing method of electronic transformer under synchronous serial coding, the field programmable gate array comprises an analog-digital conversion control module under successive connection, a data processing module, a synchronous serial coding module and a communication module, the method comprises the following steps: the analog-digital conversion control module converts the collected analog quantity signal into the digital signal via the analog-digital converter, and stores the sampling value in the converted signal data to the data processing module; the host computer generates the interpolation compensation parameter based on the data processing parameter; the communication module receives the interpolation compensation parameter generated by the host computer; processing the signal data according to the interpolation formula, and getting the data processing result; outputting the data processing result through the synchronous serial coding, the coding protocol can be configured. The data processing method of electronic transformer under synchronous serial coding achieves accuracy of different channel data with phase coincidence, and reduces the back-end data processing pressure.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an electronic transformer data processing method using synchronous serial coding. Background technique [0002] Due to the inherent characteristics of the principle of traditional electromagnetic transformers, the problems of CT saturation and ferromagnetic resonance cannot be fundamentally solved. As the country accelerates the advancement of advanced technologies such as smart grids and smart substations, electronic transformers have been rapidly promoted and applied. Compared with traditional electromagnetic transformers, electronic transformers use synchronous serial messages to output sampled value signals, and most of them use optical cables to transmit sampled value signals to provide protection, measurement and control, and metering equipment in substations. Its promotion simplifies the design of secondary cables and improves the reliability of related secondary eq...
