A Novel Scheme of Three to Five Phases Transformer Connection

Abstract

A novel scheme of three to five AC multiphase transformer to convert into DC power through modelling. The whole modelling has been simulated by using MATLAB Software. Multi-winding transformer block was taken from the sim-power system block library and turn ratios set in the dialog box then simulated. The complete design and simulation of the proposed work is presented in this paper. Now we have mentioned the simulation results only for RL load. Five phase transmission system can be developed for the generation of bulk power transfer. As per need of the induction motor under a loaded condition is used to proof the viability of transformation system. In five phase's, each phases shifted from the order by 72° (360°/5) and got the sin wave voltage/current. The connection scheme was expanded by using the modelling and simulation approach to prove the viability of the implementation.

A Novel Scheme of Three to Eleven Phases Transformer Connection by using MATLAB Software

“…The physical basis of a transformer is mutual induction between two circuits linked by a common magnetic flux. It is often used to raise or lower voltage and also for impedance transformation [1]. The transformer is an important element in the development of high-voltage electric power transmission.…”

“…The transformer is an important element in the development of high-voltage electric power transmission. Transformers can be classified into various types (step up, step down and matching transformers) according to ratio of the numbers of turns in the coils (turns ratio), as well as whether or not the primary and secondary are isolated [2].…”
