Speech Title：Research on advanced technology of optical DC voltage sensor
Abstract：The research background, development status and key problems of optical DC voltage transformer at home and abroad are introduced. A research scheme of optical voltage sensor with optical path reciprocity is proposed, and its reciprocity mechanism is described. It is deeply analyzed from the aspects of optical path structure analysis, optical path reciprocity modeling and analysis, optical path crystal modeling and analysis, optical path simulation and so on. The multi physical field coupling simulation software COMSOL multiphysics is used to simulate the transmission fluctuation of incident polarized light in electro-optic crystal, Thus, the three-dimensional wave simulation of optical wave field is realized, which provides a new research idea and theoretical reference for the analysis and design of optical path element unit of optical voltage sensor. Finally, the proposed scheme is verified by the optical path reciprocity experiment of the system.
