COMPARATIVE ANALYSIS OF A TRANSFER FIELD MACHINE AND AN INDUCTION MACHINE

ABSTRACT A comparison of a transfer field machine (TFM) and a polyp-phase induction machine (IM) is presented in this paper. Despite the fact that the two machines are from two different classes of machines and have very different physical configurations, they have identical torque – slip relationships. The transfer field machine, on the other hand, …

APPLICATION OF FUZZY LOGIC TECHNIQUE FOR POWER LOSS REDUCTION IN THE NIGERIA 330KV SYSTEM

ABSTRACT The performance of the transmission system must be increased in order to improve the overall efficiency of the power system. Reducing power losses in the system and optimizing the voltage profile are two important strategies to achieve this goal. Shunt capacitor banks in transmission substations are a significant means of managing bus voltage. The …

APPLICATION OF ARTIFICAIL NEURAL NETWORK FOR ENHANCED POWER SYSTEMS PROTECTION ON THE NIGERIAN 330kV NETWORK

ABSTRACT On the 330kV Nigerian Network modelled with Matlab R2014a, this work proposes a better protection solution based on the usage of artificial neural networks. The neural network receives inputs from measured fault voltages and currents that have been decomposed using the discrete Fourier transform implemented via fast Fourier transform. The neural network’s output plots …

AN INSULATION CO-ORDINATION PROCEDURE FOR POWER SYSTEM EQUIPMENT

ABSTRACT In general, the power system has been studied using either deterministic mathematical methodologies or statistical methods for existing Insulation co-ordination research. The existing traditional mathematical technique for insulation co-ordination analysis has a flaw in that it assumes linear power system dynamics. As a result, establishing the over voltage withstand of system elements requires a …

THERMAL MODELLING OF INDUCTION MACHINE USING THE LUMPED PARAMETER MODEL

ABSTRACT Temperature rise is a major worry in the short and long term operations of induction machines, which are the most useful industrial work symbols. The mean temperatures at the various core sections of an induction machine are investigated in this study. The thermal network of the system is created, and the algebraic and differential …

PERFORMANCE OF A HYBRID SYNCHRONOUS RELUCTANCE MACHINE CAPABLE OF ULTRA – HIGH OUTPUT POWER

ABSTRACT A hybrid synchronous reluctance machine with an ultra-high Xd/Xq ratio and output power has been investigated. The hybrid synchronous reluctance machine’s d-q model (voltage and flux linkage) has been idealized and developed. The impedance and current locations from the synchronous reluctance machine’s steady state analysis were also obtained. In the auxiliary windings, the effect …

CONSTRUCTION OF MICROCONTROLLER BASED VEHICLE SPEED ALARM

ABSTRACT The project is centered on the development of a microcontroller car speed alarm system that automatically alerts the driver by activating a panic alarm when the driver exceeds the speed restriction established in the system. The alarm is also turned off when the speed is dropped below the set limit. The car’s speed is …

CONSTRUCTION OF UNTERRUPTIBLE POWER SUPPLY

ABSTRACT When conventional utility power is unavailable, uninterruptible power supply (UPS) are utilized to provide electricity. They are not the same as auxiliary power units, emergency power units, or standby generators, despite the fact that they are frequently used for delivering electricity in remote regions or during emergencies. Unlike the aforementioned power sources, UPS supplies …
