Real Time Simulation of Single Machine Infinite Bus System Using dSPACE Controller Board

This paper presents a linear mathematical model of a Synchronous Generator with excitation system for small signal stability analysis and it proposes a dynamic simulator that is used to simulate a Synchronous power plant in real time. The state space model of the Synchronous Machine is developed using MATLAB/SIMULINK. Using Real Time Interface, the model is executed in Digital Signal Processor of dSPACE hardware, a platform for real time simulation. The model is analyzed for its performance under real time changes in input mechanical torque and reference voltage. An experimental installation of a real time platform of a Synchronous Generator thus developed facilitates its control design also.
