17Power generation industry in Poland ITCPower generation industry in PolandInstalled capacity: MW.Electricity generation of distributed power generation sector: very low – installed capacity (end of 2002 – excl. industrial power): wind power 31 MW, biogas 42 MW, small water plants 492 MW. Contribution to the energy production: 0.2%.Needed intensive development of electricity sources using renewable energy.Relatively high rate of electricity production combined with heat generation.Combined heat and power plant capacity: domination of large plants.Domination of coal in the energy sector.
18Cogeneration electricity production rate in Poland from 1985 to 2002 ITCCogeneration electricity production rate in Poland from 1985 to 2002Average for EC („old” 15) in 2000: about 10%.

21Energy efficiency and energy savings: proposals of co-operation ITCEnergy efficiency and energy savings:proposals of co-operationResearch on advanced power systems with use of hydrogen, esp. two-source systemsResearch and analysis of clean coal technologiesAnalysis of new concepts of zero CO2 emission power generation technologiesFuel cell hybrid systems - research and developmentImplementation of mathematical modelling of power installations in collaboration with distributed control systems (DCS)New concept of power plant information system
22ITC Fuel cell hybrid systems Recently, the interest in investigation on ultra-efficient electricity generation systems is focused on the application of fuel cells. From distributed generation point of view (200 kW to 20 MW), two types of fuel cells are considered: Molten Carbonate Fuel Cell and Solid Oxide Fuel Cell. These types of fuel cells require more complex configuration of power plant cycle for proper operation.The introduction of fuel cell into power plant cycle creates a hybrid system. The research and development of these hybrid systems is a key for future use of this kind of energy sources. The focus of investigations should be laid on design, off-design and dynamic simulations of hybrid systems.
23Implementation of mathematical modelling of power installations in collaboration with distributed control systems (DCS)ITCThe new abilities for data transfer and recording within the DCS make the implementation of different application software possible. The software co-operating with DCS can also generate information for the system. That makes simulation of operation of controlled installation elements possible.Examples of projects of implementation of mathematical modelling for DCS applications, realised in our Institute: digital simulator of a back-pressure extracting steam turbine, digital simulator of a steam boiler, optimisation of load distribution in captive and utility power plants (combined heat and power), software products supporting operation of power plants .
24ITC New concept of power plant information system Distributed control systems (DCS) are installed in all major power and industrial plants. The automatic collection of technical data and computer processing ability open and even force new opportunities of process control and maintenance. On the other hand, a new concept of management information system (MIS) organisation in power plants and companies should be done. The new policy on the Polish energy market strongly speeds the consolidation of generators into power concerns up. Therefore, in several enterprises kind of remote management centres will be created. New MISs need to be used for them. A concept of complex utilisation data warehouse and “power portal” (internet type GUI), which seems to be the most suitable for this kind of application, was presented in multiple papers.
