Natural Variable Modeling and Performance of Interior Permanent Magnet Motor with Concentrated and Distributed Windings

ABSTRACT Interior Permanent Magnet (IPM) motor is widely used for many industrial applications and has relatively high torque ripple generated by reluctance torque. Since the configuration of the stator has great influence on reluctance torque, different stator configuration is necessary to improve the torque performance of IPM motor. Natural variable modeling and performance comparison of Interior Permanent Magnet Motor with Concentrated winding (CW), Short pitched and Full pitched distribu...

A Fault Detection And Protection Scheme For A 200 Mva Transformer Using Fuzzy Logic

  ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of change of current with time have been identified as the input variables, duly represented in the programme as “Error” and “Error-Dot”. ...

Improved Energy Efficiency Using FACTS-DEVICE Technique: A Case Study of Ogui-Enugu Power Distribution Network.

ABSTRACT In this thesis, the objective is to determine the steady state operating condition of thirteen bus Ogui- Enugu Radial power distribution network. The steady-state was determined by finding out, for a given set of loading conditions, the flow of active and reactive powers throughout the network, the voltage magnitudes and phase angles at all buses of the network. This was achieved using Newton- Raphson power flow algorithm written in MATLAB environment. A critical analysis of the net...

High Power Loss Reduction In Enugu Electrical Distribution Systems Using Heuristic Technique For Capacitor Placement.

ABSTRACT This project involves research on loss reduction in a distribution system. The Enugu distribution system is the case study. The type of losses, the causes of losses and methods of loss reduction in distribution system were presented. A method based on a heuristic technique for reactive loss reduction in distribution system is chosen for this work because it provides realistic sizes and locations for shunt capacitors on primary feeder at a low computational burden. The Gauss-siedel m...

Performance Characteristics Of A Transfer Field Machine Operating In The Asynchronous Mode

   ABSTRACT This thesis presents the performance characteristics of a Transfer Field (TF) machine. In this machine, the two component fields revolving in the airgap are of the same pole number and the speed of operation is inversely proportional to the sum of the two pole numbers, that is, half the synchronous speed 𝜔2 of a normal induction motor. There is thus, a close relationship between the self-cascaded induction machine and the TF machine. It is shown that if the reactance of the...

Dynamic Loss Of Load Performance Of An Autonomous Self-Excited Induction Generator (Seig)

ABSTRACT The importance of Self-Excited Induction Generator (SEIG) cannot be neglected when it comes to low cost of maintenance requirement, low cost of operation, low operational cost, high reliability and availability. This dissertation presents a dynamic analysis of an autonomous Self-Excited Induction Generator (SEIG) showing dynamic loss of load performance. Analysis is carried out based of the d-q axis model, while considering the performance characteristics of the machine at constant ...
