Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.

FLUX ESTIMATORS FOR SPEED-SENSORLESS
INDUCTION MOTOR DRIVES



Abstract

This thesis deals with flux estimators for speed-sensorless induction motor drives. To enhance
the stability and the performance of state-of-the-art sensorless drives, new flux estimator
designs based on the standard motor model are proposed. Theoretical and experimental
research methods are both used. The dynamics and stability of flux estimators
are analyzed using linearized models, and the effects of parameter errors are investig ....etc

Internal winding faults resulting from the degradation of transformer winding insulation can be catastrophic and hence expensive. In the new environment of deregulation, utilities therefore are needing inexpensive methods employed to detect such faults in the incipient stage.

The development of an accurate internal fault diagnostic technique for transformers must be based on analysis of quantities from faults scenarios.

Considering the safety of personal, the damage that will occur in the transformer, the consumed time, and related c ....etc

Abstract
A significant percentage of the flux used in submerged are welding gets converted into very fine particles particles
termed as flux dust due to transportation and handling. If these very fine particles are not removed fromt he flux before
welding, it may results ....etc

1. INTRODUCTION
Electrical energy is a major requirement for the economic and industrial growth of any country. Most of the electrical energy is generated from the combustion of fossil fuels (coal, oil, gas). The fossil fuels are not only limited in nature, but generating electricity with these fuels have serious environmental, economical and safety consequences.
Energy from the sun, water, wind biomass and the ocean is renewable, biomass clean and environment friends. India has sufficient potential to develop hydro-el ....etc
