Analysis of Thermal Power Plant Main Power Equipment Depreciation Effect on its Efficiency

In the paper the steam thermal power plant (TPP) steam boiler and turbine depreciation effect on its efficiency were estimated. The analysis was carried on the real power facility using the developed technique based on the functional relation of equipment life rate and fuel consumption increase on electrical and thermal power output. The TPP technical and economic indexes calculation algorithm based on the statistical data taking into account main generating equipment depreciation for the software application was developed.
