Dynamic Equations of salient Pole synchronous Machine — Lesson 2

This lesson covers the development of equations for three-phase induction machines. It explains how to simplify these equations using notational forms and matrices. The lesson also discusses the concept of resistance and inductance matrices, and how they are used in the equations. It further elaborates on the self-inductance matrix and the mutual inductance matrix. The lesson also explains the natural reference frame description of the induction machine and the mechanical sub-system of the induction machine. Towards the end, it introduces the concept of a synchronous machine and how its description differs from an induction machine.
