Creator:: Moon, Young-Hyun
Abstract:: Ever-increasing size, complexity and operation costs in modern power systems have stimulated the intensive study of an optimal Load Shedding and Generator Rescheduling (LSGR) strategy in the sense of a secure and economic system operation. The conventional approach to LSGR has been based on the application of LP (Linear Programming)...

Creator:: Sivakolundu, Ramesh
Abstract:: Conventional generators are operated at fixed speed, and they lack the advantage of Variable Speed Generators (VSG) i.e.a VSG system is capable to maximize the electromechanical energy conversion process by varying the shaft speed. This thesis deals with a VSG system which also preserves all the functional features of a...

Creator:: NwaChukwu, David O.
Abstract:: In high voltage direct current(HVDC) systems transmission technology, a.c. power is converted(rectified) to d.c. power by means of a controlled rectifier bridge. This d.c. power is then transmitted through a d.c. link to another converter(inverter) where it is converted back to a.c. power by means of another controlled rectifier bridge....

Creator:: Yazdani-Buicki, Kiyandokht
Abstract:: A DC-to-DC power converter was designed on the basis of pulse-area modulation which is applied to a series-resonant circuit with internal frequency of 10 Khz The series-resonant circuit was placed directly in the energy path which provides a means for the thyristors to be naturally commutated. The design was tested...

Creator:: Qin, Bi-de
Abstract:: The brushless doubly fed machine (BDFM), or self-cascade single-frame machine, can operate asynchronously or synchronously over a wide speed range. In this sense the machine becomes an adjustable speed synchronous machine. Such machines may become unstable in certain regions of operation. Analyzing its steady-state performance and determining its stable operating...

Creator:: Agha-Mirsalim, Mojtaba
Abstract:: The doubly-excited machine can be used as a variablespeed generator or as a variable-speed-drive motor. In this thesis the focus is on the aspects associated with generating electric power (real and reactive) from erratic energy resources such as water or wind. In such cases, the power input to the prime...
