Model Development of Optical Devices for the Configuration of Optical Differential Protection Scheme

Abstract

This paper introduced a model development of optical devices that were utilized to build a configuration of the optical differential protection scheme. Optical current sensors were utilized as a key role in the optical differential protection scheme configuration. The optical differential protection model was conducted base on the principle of circulating current differential protection. The created configuration was a simple array of optical devices that are arranged in a series connection. Jones matrices formulations were used to represent the involved optical devices in the optical differential protection scheme, whereas Jones principle was implemented to calculate the polarization state of electromagnetic wave. Computer simulation in the Matlab environment was developed in order to assist for identifying potential design issue, predicting and assessing the optical system characteristics. The computer simulations were also verified by dissimilarity index using root mean square error method. The computer simulations including theoretical approach were used to examine the validity of the optical model and the optical configuration. Both results confirmed that the optical model and the optical configuration are valid.
