Latha, A.H.Shubhanga, K.N.2026-02-0620132013 Annual IEEE India Conference, INDICON 2013, 2013, Vol., , p. -https://doi.org/10.1109/INDCON.2013.6725978https://idr.nitk.ac.in/handle/123456789/32674This paper presents a real-time simulation of a synchronous generator using real-time application interface (RTAI) on Linux. Different generator controllers such as exciter and power system stabilizer are also included in the real-time simulation. The Forward Euler method with a suitable step-size has been employed for obtaining the solution of differential equations after justifying its applicability through illustrative examples. Various disturbance conditions are demonstrated to bring out most of the rotor-angle stability issues in a SMIB system. Using a peripheral component interconnect (PCI) card, the real-time simulation results are captured on an oscilloscope and are validated using off-line MATLAB simulations. Such a setup offers a very useful laboratory tool for carrying out the hardware-in-the-loop tests. © 2013 IEEE.Numerical integration methodsReal-time simulationRTAI-LinuxSynchronous generator
