This page describes the most common synchronous machine models used in stability studies. 4 CHAPTER Modeling and Analysis of Synchronous Machines Power quality problems of synchronous machines can be of the following types due to abnormal operation: • unbalanced load, • torques during faults such as short-circuits (e.g., balanced three-phase short-circuit, line-to-line short-circuit), out-of-phase synchronization, unbal- anced line voltages, reclosing, • winding forces during.

The approach Electric machines The starting step in the mathematical modeling of ac machines is to describe them as coupled stator and rotor polyphase circuits in terms of so-called phase variables, namely stator currents ias, ibs, ics; rotor currents iar, ibr, icr for an induction machine or if,File Size: KB.
The Simplified Synchronous Machine block models both the electrical and mechanical characteristics of a simple synchronous machine. The electrical system for each phase consists of a voltage source in series with an RL impedance, which implements the internal impedance of the machine.
The value of R can be zero but the value of L must be positive. The chapter deals with the modelling of the synchronous machines (SMs).
Following the introduction of the continuous development of the SMs, their a-b-c model is established considering the case of salient pole machines. Then, the Park transform Author: Ahmed Masmoudi.
