Prоblem 4: (а) (15 pоints) Cоnsider а 2-pole PMSM wind generаtor system delivering 1 MW with a rotor speed of 3000 RPM. Its parameters are Lm = 1 mH, Lls = 0.05 mH, and Rs = 0.002 ohms. The d axis is aligned with the rotor position, which is given to be -90° at t = 0. The flux linkage in the d-axis winding due to the rotor magnets, λfd = 1.5 Wb-turns. Assume kE = 1. Draw the per-phase equivalent circuit Calculate the phase a current Calculate phase 'b' and phase 'c' currents (b) (10 points) Briefly explain (a short paragraph or a few bullet points) each of the following: Grid forming (GFM) inverter IEEE 2800 standard
