Unformatted text preview: reference frame. Given a balanced 3-phase current with , C = 1 F, use reference frame theory to determine . Specifically, do not solve differential equations - solve algebraic equations. 5) Work through the matrix multiplications to verify the result of 6.3-14 when saliency is neglected. 6) Problems Chapter 3 -3.4, 3.14, 3.16, 3.18 7) A 3-phase system with , , , has the following dynamic model relating voltage to current in the stationary reference frame: . a) Express the steady-state form of the model and use it to determine , . b) Transform the dynamic model into the physical-variable model ( variables).
