Abstract: Static compensator (STATCOM) can provide fast and efficient reactive power support to maintain power system voltage stability. In the literature, various STATCOM control methods have been discussed including many applications of proportional-integral (PI) controllers. However, these previous works obtained the PI gains via a trial-and-error approach or extensive studies with a tradeoff of performance and applicability. Hence, control parameters for optimal performance at a given operating point may not be as effective at a different operating point. This paper proposes a new control model based on adaptive PI control, which can self-adjust the control gains during.............

Abstract: The paper addresses the power consumption profile of the University of Nigeria, Nsukka. The electricity bill of the institution which has existed for over fifty years is N14.4m on average which the University Administration sees as very excessive. The paper investigates the reasons for this high cost of electricity bills and seeks for ways to reduce these excessive bills. Load audit assessment has been adopted for the study. Audit result obtained shows that obsolete lighting loads were prevalent in the system, and non-lighting loads were based on very old technology which accounted for the high energy consumption. The result of this work shows 83% reduction for both lighting and non-lighting loads audit which translates...........

Abstract: Photovoltaic (PV) panels generator module is the widely used system solar generated powers are cascaded and connected to the grid with a constant AC supply .pv cell which gets subjected to various intensities of sun light cannot supply a constant DC voltage. A traditional method to avoid this problem is to control either of active or reactive power to control this voltage. This paper concentrates on the control of both active and reactive powers using DC-DC Converters with MPPT technique to keep the output DC voltage without fluctuations. PI controller is used to apply this MPPT technique. A comparative study of the traditional method with the proposed system has been made with the help of MATLAB Simulation.

Abstract: This paper is aimed at analyzing and developing a reliability forecasting model for an Injection Substation; a case study of Ugbowo 33/11kV Injection Substation. This project seeks to determine the current reliability state of the station and suggest realistic as well as possible remedies to ensuring high reliability. In the course of the project, data for a period of three (3) years were collected from Benin Electricity Distribution Company, Ugbowo 33/11kV Injection Substation logbooks. The data consists of the time of power outage, causes of such outage, the load loss and date of occurrence. These data were analyzed using computational techniques and a Non Linear Regression (NLR) was used in order to achieve the aim of this project. The analysis of the data shows that the average reliability......

Abstract: Automatic water level controller circuit is a simple electronics project. It can automatically switch ON and OFF the domestic water pump set depending on the tank water level. You can implement this motor driver circuit at your home or college using less costly components. The approximated cost of the project is very less. The main advantage of this water level controller circuit is that it automatically controls the water pump without any user interaction.

Abstract: This paper presents robust H2 controller design for damping power system oscillations. The proposed controller uses full state feedback. The feedback gain matrix is obtained as the solution of a linear matrix inequality (LMI). The technique is illustrated with applications to the design of stabilizer for a multimachine power system. The LMI based control ensures adequate damping for widely varying system operating conditions and is compared with conventional power system stabilizer (CPSS).

Abstract: In this paper Object Recognition technique is proposed, that produce the best idea to recognize the
object from the given input image and it is implemented in MATLAB tool. The past few years, SVM has been
applied and estimated only as pixel-based image classifiers. Recently pixel based process moving towards
object recognition technique. In an analysis, the SVMs performances are compared with some other classifiers
such that BPN classifier and KNN classifier. This technique is obtained by extracting the energies from wave
atom transform. The extracted features are given to the SVM classifier as an input and recognize the
corresponding image in an object. Finally the experimental results are shown for COIL-100 database. The
result of our proposed method is evaluated to increasing the rate of recognition accuracy and correct
recognition rate.....

Abstract: Research has yielded approaches to predict future defects in software artifacts based on historical
information, thus assisting companies in effectively allocating limited development resources and developers in
reviewing each other's' code reduces the cost of maintenance. Developers are unlikely to devote the same effort
to inspect each software artifact predicted to contain defects, since the effort varies with the artifacts' size (the
number of LOC and cost) of defects that it exhibits (effectiveness). We propose to use Genetic Algorithms (GAs)
for training prediction models to maximize.......
