This study applied a logistic regression model to determine the odds ratio of selecting clean ver-sus unclean energy as the main household fuel choice. This study also undertook to establish the coefficients of the factors determining household fuel energy choice. A large microeconomic dataset from KIPPRA’s comprehensive study and analysis on fuel use patterns in Kenya (2010) was employed to carry out the analysis. This study employed a multinomial logit regression mod-el to determine the f...
ABSTRACT In recent years the entire world is a warring about energy resources limitation, specifically Sudan country confronts critical crises in fossil fuel resources and yet more of electricity energy producing from fired thermal power plants. One from these plants Garri”2” combined cycle producing about 180MW. Exergy analysis in the light second law of thermodynamics is powerful tools to investigate from optimization of engineering devices. Exergy analysis has been carried out analytic...
This paper is a detailed study of IoT devices and effectively using them for Energy Management at our Homes. IoT Energy Management is an operation that involves organizing and administration of energy consumption patterns in numerous industries. As a part of the Smart System, Home Energy Management System (HEMS) is becoming increasingly essential, because energy consumption of urban residential sector accounts for a noteworthy amount of total energy consumption. However, a conventional HEMS h...
Primarily, the team will attempt to develop the application that the user can use it to monitor the daily energy consumption in their home. The application could generate reports data dividing by quarter or week to help users understand the source of specific energy consumption, thereby helping users save the cost of energy and protect the environment. The “big picture” of the business and the application creates an environment that enables people to live up to the values we seek to ...
Abstract: The ability to transfer power in HVAC (High Voltage Alternating Current) system has undergone limitation by reactance when compared with the fact that systems of HVDC (High Voltage Direct Current) can be accumulated to thermal limitation of the conductor. The transfer of power capabilities in HVDC and HVAC systems are compared with reference to their performance in different situations. Technological analysis conversion of existing alternating current (AC) lines into direct curre...
This paper focuses on incorporating a real time pricing in smart grids system. This scheme of real time pricing makes it possible to manage the load from the demand side or consumer side. This would provide several benefits to the domestic consumers too, apart from industrial consumers. In addition to conservation, real time pricing also comes along way in protecting and preserving the quality of equipment used by the power utility company. Real time distribution aims towards a unifo...
ABSTRACT Forced convection grain dryers are more efficient and achieve greater drying rates than natural convection dryers. However, it is necessary to provide an appropriate solar air heater in order to achieve the required drying air temperature. Well sized fan and drying cabinet, as well as an optimal combination of air velocity, temperature and grain layer thickness are also essential for improved performance of such a dryer. In order to predict variation of moisture content with time dur...
ABSTRACT Environmental pollution caused by the Municipal Solid Waste (MSW) incinerators has raised concerns about the quality of incinerators and the incineration process in Tanzania. Engineers and Scientists in general have appreciated that the installation of functional incinerators will increase the incineration process efficiency. Among the methods to achieve this is the application of mathematical modeling for the incineration process. Literatures have showed that related study in i...
ABSTRACT The dynamic simulation is one of the key steps in the validation of the design process of the motor drive systems and it is needed for eliminating inadvertent design mistakes and the resulting error in the prototype construction and testing. A quality mathematical model of induction machine based on the dynamic equations and D-Q transformation technique is presented in rotor reference frame and a computer simulation of a 7.5kW three phase induction motor was carried out based on thi...
ABSTRACT Solar cells based on ITO/InP have been shown to possess a remarkable potential for space applications. The determination of the terrestrial and simulated-space stability of any type of solar cell is important in obtaining the payload power requirements of a spacecraft which will be powered by that type of cell. In this work, a preliminary investigation of the terrestrial stability of ITO/InP cells has been performed. The cells were stored in the dark for six months in thermostaticall...
Abstract This research presents the results of numerical study of heat transfer and pressure drop behavior in a compact heat exchanger (CHE) designed with drop-shaped pin fins. The heat exchanger used for thisresearch consists of a rectangular duct fitted with different drop-shaped pin fins dimensions with the same heat transfer wetted surface area.A three dimensional finite volume based numerical model using ANSYS FLUENT 14.5 has been conducted to select the optimum pin fin dimension conside...
ABSTRACT In this research the thermal reactors have been studied, we reviewed the history of thermal reactors focusing on comparing advantages and disadvantages of using of each thermal reactors class, accordingly to these classification. we choose the pressure water reactor as the best candidate of these thermal reactors, this is due to the isolations of the second vapor cycle from the pressure and vapor system in the first cycle. This enable the pressure water reactors to be the most stabl...
ABSTRACT Poor vehicle maintenance culture and high proportions of old vehicles are major contributing factors to high vehicle emission levels. The purpose of this study was to determine performance and emission characteristics of vehicles that were taken for inspection at the Vehicle Inspection Centre in Nairobi City based on engine operating parameters and to develop performance and emission prediction models. The specific objectives were; to determine vehicle exhaust emission levels, engin...
Abstract Co-digestion of various wastes and biomass feedstock has been shown to improve the digestibility of the materials and biogas yield. In this study, the co-digestion of water hyacinth and fish waste was studied at different mixing proportions. The anaerobic digestion was carried out in batch digester reactors sized 500 ml and were charged to 10 % of total vol-ume. Co-digestion was conducted for a retention period of 21 days in mesophilic temperature ranging 25.3 °C to 33.4 °C. The re...
ABSTRACT The recent power sector reform in Nigeria has thrown up enormous challenges in this sector, ranging from the construction of more power stations, construction of new transmission lines and substations. The existing network of 8-plants and 26 bus-bars expanded to the proposed network of 16 generating plants with 49 bus-bars. This network expansion requires reappraisal for power evacuation capabilities, relay systems setting and establishment of stability margins for adverse system f...
