Research and Design of Optoelectronic Transformers

Optoelectronic transformer is the key equipment of digitized substation process layer. Introduction was made to the main functions and realization method of collector and merging unit which constitute optoelectronic transformer. Realization plan of a kind of merging unit based on ARM microprocessor and field programmable gate array (FPGA) was raised. Data transmission mode between collector and merging unit was designed reasonably. Utilizing Lagrange interpolation algorithm to process sampling value synchronously is able to meet the requirements of optoelectronic transformer well.
