What is the theoretical cycle of a simple power plant?

The theoretical cycle of a simple power plant is represented by the Rankine Cycle. This cycle is particularly significant in the context of power generation, where it is used to convert heat energy from fuel or steam into mechanical work. The Rankine Cycle involves a closed loop of water or steam as the working fluid, which undergoes phase changes: it is heated in a boiler, turned into steam, expanded in a turbine to generate power, and then condensed back into water before being pumped back into the boiler.

In this context, the cycle consists of four key processes: heating at constant pressure in the boiler, expansion through the turbine where work is done, condensation at constant pressure in the condenser, and pumping where work is input to return the liquid to the boiler. This cyclical process is efficient for power generation and provides the foundation for most modern steam power plants.

Other cycles mentioned, such as the Brayton Cycle, which is used in gas turbines, and the Otto Cycle, which describes combustion engines, do not apply as directly to the overall operation of a simple power plant compared to the Rankine Cycle. The term "Thermodynamic Cycle" is too broad and does not specify the specific mechanism of power generation that the Rankine Cycle illustrates. Therefore,
