Performance Analysis for Methods of Motor Bus Transfer System

For maintaining continuous electrical power to petroleum and chemical industries from two or more utility feeders, Motor Bus Transfer System (MBTS) is used. Higher transfer time makes residual operation inefficient where the in-phase operation require of high speed synchronize check relay which involves more cost. These characteristics will depend on the type of loads connected to the bus. This justifies the importance of comparing each method. The main objective is to compare the data of different methods and check the bus voltage and phase angle characteristics during each method. Also after comparing the values, most suitable transfer method will finally concludes the result. To accomplish the objective, PSCAD is used as simulation tool. PSCAD/EMTDC is a general-purpose time domain simulation program for multi-phase power systems and control networks. It is mainly dedicated to the study of transients in power systems.
