Simulation based Analysis of Single Unit and Parallel Connected Three Phase AC Generator in QUEST Campus Larkana

Abstract

Recently power crises are increasing day by day in Pakistan due to shortage of energy resources. The financial position of Pakistan is too weak and not in position to install new power projects for the production of electrical power to meet the demand as per requirement. So every consumer is trying to install the power producing devices to meet the demand inorder to run their institutional laboratories, offices, commercial plants and industrial machines. The generator is also one of the power producer device to meet the consumers demand to supply the electrical power to the load in absence of failure of power supply from utility company. A single large unit is very expensive to run the small loads and consume large amount of fuel, so parallel connection of two small generators is very beneficial to meet the demand as per requirement, result in cost saving, and less fuel consumption. QUEST Campus Larkana has installed two 50KVA generators in parallel to supply the required power to the load in absence of power supply to run their offices, workshops and laboratories, this minimize the cost, and increase the reliability of the system. The MATLAB simulation model is developed to analyze the performance of single unit generator and parallel connected generators.
