Plant Performance

← Previous | Next →

The Plant Performance result screen displays performance results for the plant as a whole. Heat rates and power in and out of the plant are given in a two table format.

The table on the left is standard for a Plant Performance result screen. The table on the right, Plant Electricity Requirements, provides a breakdown of the internal power consumption for the individual technology areas. These are all given in units of megawatts. Individual plant sub-components will only be displayed when they are configured on the Plant Design screen. The following results are shown in the table on the right:

•Turbine Generator Output: This is the power generated by the turbine.

•Air Compressor Use: The power required to operate the air compressor.

•Turbine Shaft Losses: This value accounts for any turbine electricity losses other than power used for the air compressor.

•Net Turbine Output: This if the net power generated by the turbine. This is the gross output of the turbine minus the power required by the air compressor and any miscellaneous losses.

•Miscellaneous Power Block Use: This is the power required to operate pumps and motors associated with the power block area.

•Absorption CO2 Capture Use: (Only shown when a CO2 Capture system is in use.) This is the power required to operate the CO2 capture system.

•Auxiliary Power Produced: (Only shown when a CO2 capture system is in use.) This is the additional power produced by the auxiliary boiler. It will be zero if no auxiliary boiler is configured.

•Component Electrical Uses: Power used by various plant and pollution control equipment is reported in the middle portion of the second column. The number displayed varies as a function of the components configured in the power plant.

•Net Electrical Output: This is the net plant capacity, which is the gross plant capacity minus the losses due to plant equipment and pollution equipment (energy penalties).

•Amine Steam Use (Elec. Equiv.): (Only shown when an amine-based CO2 capture system is in use without an auxiliary boiler.) This is the electrical equivalent energy for the regeneration steam required by the CO2 capture system. It is taken from the steam cycle.
