Abstract
For CHP plants which include fully or partially condensing steam turbine, electrical/mechanical electricity generation will decline as steam extraction increases for a given fuel energy consumption, hence there needs a balance between increasing heat energy recovery and reducing electrical/mechanical energy output assuming a constant fuel energy input. Through a daily energy supply data over a year in one of the cogeneration power plants in Thailand, the influence of power loss coefficient to Primary Energy Saving (PES) or efficiency is analyzed. Power loss coefficient used in the calculations was defined as per the basic theory of power loss coefficient in CHP Manual by EU Parliament and CHP Methodology by UNFCCC. Calculation of saving of primary energy according using cogeneration system follows the EU Manual; setting of CHP overall efficiency must be same with overall efficiency of power plant. Power loss coefficient just makes senses for calculation of power generated by CHP mode. Variations of the reference values for the calculation of the PES are shown as the reference values (RV) of both electrical and heat efficiency have a very big influence on the PES criteria. Other factors, like “credits” for distributed generation and the influence of the ambient temperature on the RV are shown as well.
