ABSTRACT: An analysis for a conceptual design of a thermal power plant (with a
power capacity of 1 GW) is provided. This power plant can help in meeting the
expected increase in the electric demand for Oman’s dominant power system (2.4
GW between 2018 and 2025). A necessary fluid mass flow rate of 834.1 kg/s was
predicted. The overall energy conversion efficiency (output useful electricity
divided by input heat) was estimated to be 34.7%. The needed thermal energy is
not restricted to a specific source, and solar heating is an option for
supplying the needed heat. The power plant design is based on using a
steam-turbine section, which may be composed of a single large steam turbine
having a mechanical power output of 1115 MW; or composed of a group of smaller
steam turbines. The analysis is based on applying energy balance equations
under certain assumptions (such as neglecting changes in potential energy). The
thermal analysis was aided by web-based tool for calculating needed properties
of the working medium, which is water, at different stages in the power plant.
