Control Of High Power Wound Field Synchronous Motor Drives - Modelling Of Salient Pole Machine, Field Oriented Control Using VSI, LCI And Hybrid LCI/VSI Converters
(2013-05-02)
This thesis proposes control schemes and converter configurations for high power wound field synchronous motor (WFSM) drives. The model for a salient pole WFSM in any general rotating reference frame is developed which can ...
Power System Stabilizing Controllers - Multi-Machine Systems
(2013-05-02)
Electrical Power System is one of the most complex real time operating systems. It is probably one of the best examples of a large interconnected nonlinear system of varying nature. The system needs to be operated and ...
An Efficient Solution To Generalized Model Of A Transformer Winding And Localization Of Discrete Changes Based On Measurements
(2008-01-31)
High voltage power transformers are designed to withstand a variety of overvoltages and short circuit forces. Occurrence of these events in a power system is natural, inevitable, and one of the main causes of transformer ...
Construction Of Equivalent Circuit Of A Single Isolated Transformer Winding From Frequency Response
(2013-06-14)
Frequency response analysis (FRA) of transformers is universally accepted as a highly sensitive tool to detect deformations in its windings. This is evident from the fact that customized commercial equipment (popularly ...
Control, Modulation and Testing of High-Power Pulse Width Modulated Converters
(2018-04-02)
Experimental research on high-power converters, particularly in an academic environment, faces severe infrastructural constraints. Usually, power source and loads of required ratings are not available. Further, more ...
Studies On Polymeric Micro/Nanocomposites For Outdoor High Voltage Insulation
(2011-05-10)
Outdoor electrical insulator is one of the important components of a power system which directly influences the system reliability. Traditionally ceramic insulators have been used for close to a century in both transmission ...
Sub-Nyquist Sampling and Super-Resolution Imaging
(2018-07-04)
The Shannon sampling framework is widely used for discrete representation of analog bandlimited signals, starting from samples taken at the Nyquist rate. In many practical applications, signals are not bandlimited. In order ...
