Simulink Analysis of Vector Groups of Transformers Installed at 132kV Grid Station Qasimabad, Hyderabad and their Effects on System Operation

Sunny Katyara, Sunny Kumar Gemnani

Abstract: In this paper we have simulated the vector groups of transformers installed at 132 kV Grid Station Qasimabad Hyderabad Pakistan with the use of MATLAB Simulink Software. We also make some real time changes in the vector groups of the installed transformers and would analyze their effects on the system operation. The main objective of this paper is to understand the vector groups of transformers, their need in the transformer parallel operation and to make comparative analysis by considering different scenarios of vector groups for transformers installed at 132 kV Grid station Qasimabad Hyderabad Pakistan.
