Title : Corrosion Behavior of Al-Ni Matrix Composites in a dilute sodium chloride solution

Abstract :

Aluminum Matrix Composites (AMCs) have been used in several applications in aerospace and automotive industries. Although several technical challenges exist with casting technology. Achieving a uniform distribution of reinforcement within the matrix is one such challenge, which affects directly on the properties and quality of composite. Hence, this work aims to improve the mechanical and corrosive resistance of aluminum by reinforcing with yttrium oxide and nickel through stir casting using vortex technique. Al-Ni- Y2O3 composite with the percentage of Ni fixed at 20 % and Y2O3differed through 3-9% in increments of 3 wt.%. The hardness value of the aluminum matrix composite improved with increased percentages of Y2O3, and the maximum increase was obtained for 9% Y2O3 composite, viewing an increase of about 52%. Potentiostatic polarization test for the Al-20%Ni base alloy and the prepared composite were carried out in 3.5wt% NaCl solution as corrosive medium. There was a noticeable improvement in the corrosion resistance of the aluminum composite compared to its purest form, owing to the presences of nickel. However, the increase in Y2O3 percentage decreased the corrosion rates. The extreme decrease in corrosion rates was obtained for 6% Y2O3 composite in 3% wt. NaCl solution which reach to 5.51 in (mpy) unit for composite material which is lower than that of the base alloy 118.59 (mpy).

Title : Incidences of Voltage Collapse in the Nigerian Power System: Data and Analysis

Abstract :

The work presents a study of voltage collapse in Nigeria Power Network. This involves the series of events accompanying voltage instability which lead to a blackout or abnormally low voltages in a significant part of the power system. The cause of this can be categorized into two; technical and non-technical. The technical causes may be due to tripping of lines on account of faulty equipment or increase in load than the available supply. The data comprising the series of system collapse experienced by the Nigeria power system since 2000 to 2020 were presented and analyzed so as to view the frequency of the occurrence of the collapse. Also, suggestions were given on the ways to reduce the incidence of system collapse on the power system. The need for an approach to voltage collapse margin which is to return back the system to steady state by injection/compensation of reactive power on the transmission lines becomes urgent with other use of tap- changing transformers and load shedding strategies. These compensators which are presented in this work are SVC, STATCOM, TCSC, SSSC and UPFC are the approaches used. PSAT software which makes use of Newton-Raphson’s iterative method was used to simulate the existing 52-bus system of Nigeria which displayed high accuracy and converged in few numbers of iterations. SVC and STATCOM were first used separately to compensate bus1 (0.9673pu) while TCSC, SSSC and UPFC were later used separately to compensate the system. Results obtained showed that the use of dynamic shunt compensators (SVC and STATCOM) maintained the bus 1 voltage at 0.9673pu while the use of series compensators (TCSC, SSSC and UPFC) slightly maintained a power flow of 80MW and bus 1 voltage at 0.9673pu after several increases in loadings. It is with this that the research work presents the use of series compensators on the transmission lines as the optimal approach to voltage collapse in Nigerian Power system. An Optimal site for the placement of the series compensator is at Bus 8 (Jos) and Bus 9 (Gombe) which have the lowest loss of sensitivity index. The installation of any of the series compensators in Nigeria power network keeps the system in steady state at all times.
