Managing Knowledge in the Electric Power Production Sector

Knowledge management is a topic of increasing involvements in strategic development of the Electric Power Production Sector in Croatia particularly because of the recent emergence of unification and integration of the European Electric Power market. New ways of thinking about management and organization are a key for Croatian participation in the European Union and in an integrated European Power market. Management of knowledge is the most important point of new sustain development towards the appropriate position of Croatian Electric power production sector in the European integration processes. The awareness of importance of processing and managing knowledge is of vast importance as a focus on an application capacity of information science. It is a means to enable establishing hard connections between business activities and the development of information sciences

Electric power generation using geothermal brine resources for a proof of concept facility

An exploratory systems study of a geothermal proof-of-concept facility is being conducted. This study is the initial phase (Phase 0) of a project to establish the technical and economic feasibility of using hot brine resources for electric power production and other industrial applications. Phase 0 includes the conceptual design of an experimental test-bed facility and a 10-MWe power generating facility

Coal conversion products industrial applications

Coal-based synthetic fuels complexes under development consideration by NASA/MSFC will produce large quantities of synthetic fuels, primarily medium BTU gas, which could be sold commercially to industries located in South Central Tennessee and Northern Alabama. The complexes would be modular in construction, and subsequent modules may produce liquid fuels or fuels for electric power production. Current and projected industries in the two states which have a propensity for utilizing coal-based synthetic fuels were identified, and a data base was compiled to support MFSC activities

Using Proactive Maintenance Strategy for Sustainable Electric Power Production in Nigeria

An unpleasant turn of events would compel and prevail upon power plants owners and operators looking for alternative for keeping maintenance activities up and awake. Thus, causing a break away from outdated traditional system originally practiced in maintenance organizations, which affects operations in terms of costs and energy required for sustainable activity in the power production industry; via Generation, Transmission and Distribution. However, the only inevitably obtainable option as per organizational success in the power industry is through a substituent for a failure based system with success based strategy that is concerned with optimization of complex processes, systems or organization by developing, improving and implementing integrated systems of people, money, knowledge, information and equipment, central to manufacturing and production operations. A platform intended to deliver on plant (a) availability (b) reliability and (c) sustainability, which lead to reduced maintenance costs and increased profitability.

GAS TURBINES CONNECTED BEFORE HOT WATER BOILERS

Due to the efficiency of heat utilization equipment connected after gas turbines, the use of this equipment is widespread. This study examines the use potential of gas turbines connected before hot water boilers, also widely used in Hungary, to determine, in addition to electric power production, how reliable operation can be maintained with as little modification of the heat utilization equipment as possible. The recommendation is suitable for electric power production in both normal and peak operation since it retains the original burners together with their blowers. This study has been made in relation to boilers in Hungary, of about 15 PTVM-I00 units and 1 PTVM-180 unit. This study includes the basic parameters of the gas turbine, the parameters needed to determine its energy conditions, the recommendation for the so-called canal burner placed after the gas turbine and the power engineering parameters of the boiler

Solar thermal plant impact analysis and requirements definition study

The technology and economics of solar thermal electric systems (STES) for electric power production is discussed. The impacts of and requirements for solar thermal electric power systems were evaluated

Solar sustained plasma/absorber conceptual design

A space power system concept was evaluated which uses concentrated solar energy to heat a working fluid to temperatures as high as 4000 K. The high temperature working fluid could be used for efficient electric power production in advanced thermal or magnetohydrodynamic conversion cycles. Energy absorber configurations utilizing particles or cesium vapor absorber material were investigaed. Results of detailed radiant heat transfer calculations indicated approximately 86 percent of the incident solar energy could be absorbed within a 12-cm-dia flowing stream of gas borne carbon particles. Calculated total energy absorption in the cesium vapor seeded absorber configuration ranged from 34 percent to 64 percent of the incident solar energy. Solar flux concentration ratios of between approximately 3000 and 10,000 will be required to sustain absorber temperatures in the range from 3000 K to 4000 K

THE OPTIMAL FLAT PANEL SOLAR THERMOELECTRIC GEOMETRIES FOR HEAT AND ELECTRIC POWER PRODUCTION

A calculation technique provides direct calculation of the heat and electric power of flat panel solar thermoelectric system is established, this was in order to determine the optimum system size optimization for combined water heating and electricity generation. The system size optimization is trade-off between the thermoelement length, cross-section area and the solar absorber size. The technique is developed under the conditions of given solar irradiation, the thermoelectric (TEG) cold side temperature, cross-section area and number of thermoelements. The calculation technique is verified by experimental setup, which comprises of uncovered flat black painted solar absorber, a heat sink partly submerged on water system and TEG device which was sandwiched in between, 5 commercial TEG devices of different sizes were examined, the steady state TEG open circle voltage and temperatures were measured to evaluate the electric and thermal power experimentally. The data obtained through the calculation technique was validated against the experimental data. The results show that there is an optimum size of the system, decreasing or increasing the size further wouldn’t achieve the optimum performance. The established calculation technique provide the designer (manufacturer) and users with good indication of what TEG size they should use, thus saving the user’s time of examining different TEGs with different aspect ratios (sizes ) and saving manufacturing cost by using less material
