HARDWARE IN THE LOOP SIMULATION OF ENERGY SYSTEMS IN THE VTB ENVIRONMENT

this paper describes new results related to hardware in the loop (HIL) computer simulations within the Virtual Test Bed (VTB) simulation environment. Implementation of HIL simulations expands the possible applications of time domain simulators and provides hardware-specific results which are not easily obtained by other techniques. Hardware in loop increases the validity and accuracy of the system simulation and relieves one of identifying all of the parameters of at least one of the system models. The modified coupling scheme that improves the stability of HIL simulations is described, implemented and tested on a practical electromechanical system.
