TLDR
In this paper, the performance of a large generator under abnormal operating conditions through physical modeling and simulation is investigated. But the authors focus on the performance analysis of a single generator and do not consider the effects of different operating conditions on the generator.Abstract:
Micromachines are small machines specially designed so that their parameters, on a per unit basis, are similar to those of large generators in power systems, and they are widely used to study the performance of these large machines under abnormal operating conditions through physical modeling and simulation.read more

Development of a Test Rig for Fault Studies on a scaled-down DFIG
TL;DR: In this paper, an experimental test rig has been set up based on a 5kW wound rotor induction machine (WRIM) that was developed and built in the university laboratory as a scaled-down version of a typical 2.5MW doubly fed induction generator (DFIG), with the main aim of conducting various fault studies on the developed micromachine.

Excitation Limiters Design for a Micro-Alternator Buck Converter Based Static Excitation System
TL;DR: In this article , the authors present the design of excitation limiters such as an under-excitation limiter, over-exciting limiter and V/Hz limiter as per IEEE STD 421.5 and implemented on a DC-DC buck converter-based static excitation system to protect the generator during abnormal conditions such as overloading, overheating and over-fluxing of the machine.
