پایایی و دقت در مورد سخت افزار قدرت - در حلقه تست نیمکت برای توربین های بادی

In Power-Hardware-In-the-Loop (PHIL) setups, the device under test (DUT) is connected to the rest of the system (ROS) running in a real-time simulator through an Interface Algorithm (IA) and power amplifier, which strongly influences stability and accuracy of the test setup. This paper presents a comprehensive theoretical framework for the analysis of the two aspects of a PHIL system with different IAs, and demonstrates its applicability to the design of PHIL test benches for wind turbines. For the theoretical modelling derivation, the interaction of two lumped active systems is considered.
