Control of a Superconducting Magnetic Energy Storage unit for Synchronous Generator Damping Enhancement

Abstract

In power system, oscillations may occur due to load change or system fault which creates unsynchronized and undamped signals and creates instability in the system. So to enhance dynamic stability of the system, a control mechanism is constructed for Superconducting magnetic energy storage (SMES) unit to enhance the damping of the power system. Proportional Integral (PI) controller is utilized to improve damping of oscillation of a synchronous generator connected to an infinite bus. Eigen values of system are found using matlab which helps in minimizing the oscillations caused by disturbances and enhances damping. PI controller parameters are found by using pole assignment technique Response curves are generated in Matlab to compare the difference between the damping of oscillations for synchronous generators without PI controller and with PI controller with SMES
