This paper deals with the current state-of-the-art in interfacing issues related to real-time digital simulators employed in the simulation of power systems and power-electronic systems. This paper provides an overview of technical challenges encountered and their solutions as the real-time digital simulators evolved. Hardware-in-the-loop interfacing for controller hardware and power apparatus hardware...
The closed-loop stability and the simulation accuracy are two paramount issues in power hardware-in-the-loop simulation in regard to the operational safety and the experiment reliability. In this paper, the stability issue of the power HIL simulation is first introduced with a simple example. A stability analysis and accuracy estimation method based on the system's loop transfer function is later...
This paper describes the basic concepts behind controller hardware-in-the-loop (CHIL) and power hardware-in- the-loop (PHIL) experimental testing from a renewable energy system integration perspective. An entire power apparatus or sub-system such as a power electronics converter for a fuel cell system or a variable speed wind power generator system can be tested in a controlled laboratory environment...
Hardware-in-the-loop (HIL) simulation has been used in the past primarily for testing system interactions of control systems. Extending the concept of HIL into the realm of real power equipment, such as motors and power electronic converters, results in the so-called power hardware-in-loop (PHIL) simulations. The Center for Advanced Power Systems (CAPS) at Florida State University is currently in...
