Analysis of Voltage Stability in Two Machine System with SVC Using MATLAB Simulation

Abstract

Power system is a wide network and consists of generation, transmission and distribution. In the era of development, demand of electric power demand is increasing tremendously. For fulfilling this demand the generation capacity is increased, also restructuring in some countries add to the power system complexity the most effected components of power system with this advancement are transmission and distribution system, besides rotor angle stability correction of power factor and compensation of active and reactive power. Power system also concerns about the transients in voltage. Requirement of good power quality along with additional load make the compensating device a necessity in the modern era of power system. This modern world demand of electricity is increasing which in turns load the system due to need reactive power days. The reactive power is given by the FACTS devices. Facts devices used for many purposes in power system. The simulation of the model of transmission network along with compensating device SVC is being done in MATLAB. Simulation results for changing load with and without SVC are analyzed.
