Mathematical modelling of synchronous machine. Sep 1, 2013 · The mathematical model of the synchronous motor is typically derived by applying the unified theory of electrical machines, which states that any electrical machine is dynamically describable by The primary objective of an electrical power system is to maintain balanced sinusoidal voltages with virtually constant magnitude and frequency. The complete mathematical description of the system would therefore be very complicated unless some simplifications were used. This chapter presents some basic mathematical models of these components and their associated control systems. edu.
