Since large power transformers belong to the most valuable assets in electrical power networks it is suitable to pay higher attention to these operating resources. Thermal impact leads not only to long-term oil/paper-insulation degradation; it is also a limiting factor for the transformer operation. Therefore, the knowledge of the temperature, especially the hottest spot (HST) temperature, is of high interest. This paper presents steady state temperature distribution of a power transformer layer-type winding using conjugated heat transfer analysis, therefore energy and Navier-Stokes equations are solved using finite difference method. Meanwhile, the effects of load conditions and type of oil on HST are investigated using the model. Oil in the transformer is assumed nearly incompressible and oil parameters such as thermal conductivity, special heat, viscosity, and density vary with temperature. Comparing the results with those obtained from finite integral transform checks the validity and accuracy of the proposed method

The dye-sensitized solar cells (DSSC) have gained the last decades an important place among photovoltaic technologies due to their low-cost of implementation and their performance, which becomes more efficient. The experimental data for this type of cells are enriched and accumulated quickly, given the enthusiasm for this new technology. The present work treats the equivalent circuit of a dye-sensitized solar cell (DSSC) for a model in an exponential, and by using the results of some works, we shall make a simulation by the software Scilab to obtain the characteristics (I-V), then we will study the influence of every parameter on the curve.

Employing Resistive Superconducting Fault Current Limiters (RSFCL) is one of the practical and effective methods to improve the transient stability of a power system by limiting the fault current. Regarding technical and economical constraints, optimal sizing and allocation of RSFCLs in a power system is of significant importance. It is the purpose of this paper to propose an algorithm based on the Particle Swarm Optimization (PSO) in order to improve the transient stability of a power system by optimal sizing and allocation of RSFCLs. The proposed algorithm is next applied to the New England 39-bus test system as a case study and the results are simulated in Matlab. Simulation results reveal that in the case of employing RSFCLs with sizes and locations resulted from the optimization algorithm, the transient stability of the power system under study is improved. Furthermore, it seems that the optimal locations of RSFCLs are to some extent near the fault location.

In Databases one of the active research fields is mapping relational databases (RDB) into Resource Description Framework (RDF). An enormous data is kept in the form of relational databases and accessing of data is done in the semantic web. The data stored in RDB is to be efficiently mapped to the semantic web or RDF for data availability to the users. There is a definite need for improvement in technologies for efficient mapping languages from RDB to RDF in semantic web. This paper presents an up-to-date survey of different RDB to RDF mapping languages proposed in recent times. It outlines the main features or characteristics to be considered for efficient mapping in different scenarios. The main objective of this content, pictures identification of limitations existing in the mapping languages. It also enhances the comparisons between each language and helps researchers to propose further better proposals in their future scope of work to improve better mapping techniques.

Man’s history and development endeavours have beenadvancing alongside a trail of ecological ramifications and climate change. Since prehistoric times, scientists have not recorded an accelerated shift in the ecologyof the planet during any other epoch beside that of modern man. The paper seeks to explore how man’s history and developmentaffects ecologyand climate. It uses desk analysis to recollect data from global assessment reportsand runs a One paired Sample Means t-Test, 1 tailed, 8 df, at Pearson Correlation value 0.458 and 0.5 alpha level. Findings show that, there is globalclimate change, seen in global warming trends; andimbalance in ecological footprint, seen in depletion of air, water and land sinks. The t-Test reveals significant net loss of global forest cover.The study also,apparently found that, processes ofdevelopment generally tend to damage ecology. Therefore,the study recommends a refocus to sustainable means of development.

A way of exploiting the solar energy is to use cells photovoltaic which convert the energy conveyed by the incidental radiation in a continuous electric current. This conversation is based on the photovoltaic effect engendered by the absorption of photons. A part of the absorbed photons generates pairs electron-hole in which an electric field created in the zone of load of space of a junction p–n. Thus, the junction p-n, its characteristics, its components and its dimensions are the parameters responsible of the efficiency and the performances of a solar cell. To study this, we are going to use a very known software in the mode of the simulation of solar cells, the PC1D, and we are going, at the end, to draw a conclusion around the ideal parameters that a good solar cell has to have.

This paper contributes to design a Wind Emulator coupled to 1.5 kW Induction generator for Wind Energy Conversion System. A wind turbine emulator (WTE) is important equipment for developing wind energy conversion systems. It offers a controllable test environment that allows the evaluation and improvement of control schemes for electric generators that is hard to achieve with an actual wind turbine since the wind speed varies randomly. In this paper a wind emulator is modelled and simulated using MATLAB. Verification of the simulation results is done by experimental setup using DC motor-Induction generator set, LABVIEW and data acquisition card.

Mathematical heat transfer equations for finned double pipe heat exchangers based on experimental work carried out in the 1970s can be programmed in a spreadsheet for repetitive use. Thus avoiding CFD analysis which can be time consuming and costly. However, it is important that such mathematical equations be evaluated for their accuracy. This paper uses CFD methods in evaluating the accuracy of mathematical equations. Several models were created with varying; geometry, flue gas entry temperature, and flow rates. The analysis should provide designers and manufacturers a judgment on the expected level of accuracy when using mathematical modelling methodology. This paper simultaneously identifies best practices in carrying out such CFD analysis.

Energy dependent small developing island states are besieged to sustain potential rate of growth. This is due to increase in energy prices and lack of evidence based policy on long term sustainable energy use. This paper examines the long run relationship between economic growth, export and electricity consumption in Fiji over the period 1981-2011. Employing Granger causality test it is found that there is cointegrating relationship between economic growth, export and electricity consumption. The casual relationship between the variables was investigated within the error correction model framework. We found that in the long run causality runs from electricity consumption and export to economic growth. Based on this empirical analysis some important policy implications are suggested.

ZnO thin film were deposited by spray pyrolysis on glass substrates, using zinc nitrate as precursor with different molar concentrations varying from 0.05M to 0.2 M. To study the structural proprieties of the film , the different technique was used as the X-ray diffraction, atomic force microscopy (AFM), Raman scattering , and FTIR . The optical properties were explored by transmission, reflectivity and Photoluminescence techniques. The ZnO thin films obtained in this paper are polycrystallines, the grain size increases when the molar concentration of Zn precursor was increasing. The films are transparent in visible region, this transmission values decreases when the molar concentration increase caused by the increasing of surface roughness

A detailed investigation covering piped gas flow characteristics in high pressure flow conditions. Such flow analysis can be resolved using established mathematical equations known as the Fanno condition, which usually cover steady state, or final flow conditions. However, in real life, such flow conditions are transient, varying with time. This paper uses CFD analysis providing a split second “snapshot” at what happens at the pipe outlet, and therefore, a closer understanding at what happens at the pipe’s outlet in high pressure gas flow condition. In this example air was selected for simulation purposes. In HVAC applications, such gas flow conditions can occur in typical applications such as; air compressors releasing high pressure air through a pipe, or compressor over pressure refrigerant gas being released into the atmosphere via a discharge pipe. Investigation has shown that rather than a steady mass flow rate condition occurring at the pipe outlet, calculated by the Fanno flow condition, a spiked increase in flow rate occurs at the beginning,and then stabilizing after a few seconds, with relatively minor ripples in flow rate. Other observations were also made and commented. CFD results in mass flow rate were compared with the mathematically derived results, differences were recorded. The CFD analysis showed how the k-omega turbulence model performed well, with the processor stabilizing at an early stage.

Solving the unit commitment (UC) problem is one of the most complicated issues in power systems that its exact solving can be calculated by perfect counting of entire possible compounds of generative units. UC is equated as a nonlinear optimization with huge size. Purpose of solving this problem is to programming the optimization of the generative units to minimize the full action cost regarding problem constraints. In this article, a modified version of ant colony optimization (MACO) is introduced for solving the UC problem in a power system. ACO algorithm is a powerful optimization method which has the capability of fleeing from local minimums by performing flexible memory system. The efficiency of proposed method in two power system containing 4 and 10 generative units is indicated. Comparison of obtained results from the proposed method with results of the past well-known methods is a proof for suitability of performing the introduced algorithm in economic input and output of generative units.

A concept of a liquid tin anode-indirect carbon air fuel cell (LTA-ICFC) are described. Experimental setups for analysis of LTA-ICFC polarisations of an operational electrochemical reactor of the LTA-ICFC are presented. Results from Electrochemical Impedance Spectroscopy (EIS) Analysis of the electrochemical reactor of the LTA-ICFC are shown and analysed.The rate-determining step of the system is concluded. The charge-transfer resistance did not show considerable differences at 700-800 °C. This can be implied that the charge-transfer resistance is not the rate-limiting step of the transport processes of the fuel cell. The increase of the Warburg impedance concurrently with the resistance to fit mass-transport loss (R3) suggests that the rate-limiting step for the LTA-ICFC in voltage recovery mode is the diffusion of the oxide ions through SnO2 layer. The increment of mass transport lost, R3, of the cell causes the slowly increase of the cell’s voltage over the voltage from 0.7-0.8 V at 700, 750, and 800 °C.

Southeast Asia comprises an extraordinarily diverse set of countries with vast differences in the scale and patterns of energy use and energy resources endowments. Indonesia and Thailand have been selected to be compared because they are the two largest consumers in energy sector in the region and both countries still similarly rely on energy imports such as oil. They have been facing challenges in energy policy reformation distorting energy markets. The combined energy status of Indonesia and Thailand not only aims at providing policy makers with an understanding of the energy trends and challenges being faced by the countries up to the next two decades, but also at confidently convincing them the future energy pathways to unlocking energy efficiency potential and investment. This work contains data and information on pattern of energy use in the past, present, and future, some economic and political factors that may be affecting energy demand and supply of Indonesia and Thailand. Key energy issues that need to be considered are introduced. The potential future energy pathways are included and compared between the countries. Investment opportunities in each country are also identified.

In Orkney islands, a number of wind energy projects have been established due to its potential for wind energy development especially as cluster developments on hilltop and moorland. This Self-sufficient Orkney Wind Energy (SOWE) project is trying to follow this pattern of development and has designed as a simple linear development of medium-large scale wind turbines which avoids dominating the landscape, while providing diversification required for the energy security, along with strong economic benefits to the local community. The developer completed preliminary designs and landscape assessment, resulting in the detailed design and the development of 27 wind turbine project for the expectation to generated electricity of 549.2 GWh annually.

The world is now facing energy scarcity and climate change. In that context, renewable energy is gradually replacing fossil fuels. However, this source of energy has not been fully exploited. Some natural disasters bring a lot of energy but are not exploited; in particular, storms are among the heavyweights. In this paper, I propose a device for harvesting energy from wind, waves and especially storms. One such device is called a Stormbuoy. If used in practice and deployed on a large scale, the Stormbuoy will harvest significant amounts of energy from wind, waves and storms. This not only solved the problem of energy scarcity but also mitigated the destruction of the storm with humans.

Rural ecosystems are the main source of biomass used in the production of renewable energy in Portugal. However, it is based on pruning residues are most of the raw material for biomass leaving other opportunities aside. This paper highlights the role of pinecone waste without pinion for the energy sector. The present paper studies different solutions to enhance the use of the pinecones for energy proposes. The present paper also presents the different principal technologies. It is possible to conclude that the use of residual biomass is a way to reduce the national dependence on energy imports (fossil specialties), decreases transport losses (by allowing local production and consumption locally) and encourages the management of forest areas (fixing people in rural areas and lowers the risk of fire).
