» ABSTRACT A power system is set up basically to meet the demands of the customers. However, interruptions which are largely unavoidable contribute to the unavailability of power and thus prevent power system from achieving this. In most cases, it is the sustained interruptions that greatly affect both the utility company and its customers. Hence, it is necessary to find means of determining which c...Continue Reading »

» ABSTRACT This work presents a comparative analysis of a transfer field machine (TFM) and a polyp phase induction machine (IM) . Although the two machines belong to two different classes of machine and quite different in physical configuration , yet both display similar torque – Slip characteristics. However, the synchronous speed of the transfer field machine is ωo/2, that is, one half...Continue Reading »

» Abstract This work investigates an improved protection solution based on the use of artificial neural network on the 330kV Nigerian Network modelled using Matlab R2014a. Measured fault voltages and currents signals decomposed using the discrete Fourier transform implemented via fast Fourier transform are fed as inputs to the neural network. The output plots of the neural network shows its successf...Continue Reading »

» ABSTRACT Generally, for existing Insulation co ordination studies the power system has been modeled either by deterministic mathematical techniques or by statistical methods. The shortcoming of the existing conventional mathematical technique of Insulation co ordination analysis is that it assumes that the power system dynamics is linear. This makes analysis of over voltage response of the system ...Continue Reading »

» ABSTRACT The performance of a hybrid synchronous reluctance machine capable of ultra high Xd/Xq ratio and output power has been studied. A d q model (voltage and flux linkage) of the hybrid synchronous reluctance machine has been idealized and developed. Also, the impedance and current loci from the steady state analysis of the synchronous reluctance machine was obtained. The effect of capacitor l...Continue Reading »

» ABSTRACT Uninterruptible power supplies (UPS) are used to provide power when regular utility power is unavailable. Although they are commonly used for providing power in remote locations or emergencies, this is not because they are the same as auxiliary power units, emergency power units or standby generators.Unlike the aforementioned power sources, UPS provides an immediate and continuous supply ...Continue Reading »
