Energetic autonomy of a hydraulic-based mobile robot requires a power source capable of both hydraulic and electrical power generation. The hydraulic power is used for locomotion, and the electric power is used for the control computer, sensors and other peripherals. In addition, the power source must be lightweight and quiet. This study presents several designs of internal combustion engine-ba...

INTRODuCTION POWER electronics is a technology for using power devices to convert efficiently electric power into the optimum characteristics. As a key component for improving the energy efficiency and performance of various equipment, power electronics contributes to the realization of both a prosperous and comfortable way of life and a sustainable society by reducing CO2 (carbon dioxide) emis...

clean hydrogen is the major energy carrier for power production. the conversion of co to co2 and zero emission during hydrogen energy production causes high capital cost. it is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. in this era, coal gasification is the most promising technology for t...

As the aircraft industry is moving towards the all electric and More Electric Aircraft (MEA), there is increase demand for electrical power in the aircraft. The trend in the aircraft industry is to replace hydraulic and pneumatic systems with electrical systems achieving more comfort and monitoring features. Moreover, the structure of MEA distribution system improves aircraft maintainability, r...

This article examines possible explanations for increased utilization of Powder River Basin (PRB) coal in electric power generation that occurred over the last two decades. Did more stringent environmental policy motivate electric power plants to switch to less polluting fuels? Or, did greater use of PRB coal occur because relative price changes altered input markets in favor of this fuel. A ke...

Electric power industry should play a bigger role in energy conservation and emission reduction, while the ecosystem degradation rises because of the shortage of energy, the greenhouse effect and the environmental pollution. Power generation dispatch is the key practice in electric power industry. In this paper, the value based dispatch theory is proposed, which assign the value of the natural ...

Fuel cells are treated as flow engines driven by fluxes of chemical reagents and electrochemical mechanism of electric current generation. Analyzed are performance curves of a SOFC system, power limits and the effect of typical design and operating parameters on the cell performance. The theory combines a recent formalism worked out for chemical machines with the Faraday’s law which determines ...

The electric power industry requires qualified personnel to support an optimal and safe operation. Since its beginnings, the IIE has been developing different training technologies and systems for CFE, the main utility for generation, transmission and distribution of electric power in Mexico. Some of these endeavors provide tailored instruction considering trainees traits such as learning style...

Automatic generation control in electric power system design is a major concern nowadays due to its rising size, varying structure, integration of renewable-energy sources and distributed generators to meet the growing demand. In this paper, automatic generation control of an interconnected four area hydro thermal system examined. Each area equipped with reheat turbine for thermal system and hy...
