摘要

In an attempt to create a new control method for the power interface in PHIL simulations, a simulated PHIL simulation is carried out where the simulation and hardware part are modelled in MATLAB/Simulink along with the new control method. This power interface control is proposed to achieve high accuracy in PHIL simulation with closed-loop control for aerospace, marine or micro grid applications. Rather than analyzing the Real Time Simulator (RTS) data and controlling the interface using time-domain resonant controllers, the RTS data will be analyzed and controlled at the interface in the frequency domain, on a harmonic-by-harmonic and phase-by-phase basis. This should allow the RTS time delay to be compensated accurately, and removes the requirement to include additional components to compensate for the simulation delay into the simulated power system as it is not appropriate for power systems which have short transmission lines. This is extremely relevant for marine and micro grid scenarios where such inductive components may not be present.
