Thermodynamic Optimization Tools for Power Tracking in a Multistage Concentrated Solar Power Rankine Plant

Publication: Journal of Energy Engineering
Volume 143, Issue 1

Abstract

The object of the study is to present a method of thermodynamic optimization of power generating plants, in a mode that consolidates and simplifies the analysis of data on heat-work interaction of the plant components. The optimization scheme identifies the technical and process parameters that can improve the thermodynamic performance of the plant with respect to an objective variable, and further, the required thermodynamic measures necessary to improve the operating condition of the plant. Simple but effective tools are used to evaluate the optimal and suboptimal power generating capacities vis-à-vis the fundamental variables—namely, the thermodynamic quantity ratio (TQR) and the power-energy quantity ratio (PQR)—without routing optimization procedures. Beyond the optimal value of the objective variable, the power generation capacity of the plant is affected. The determination of the optimal value of the objective variable can also be approached by computerization; for fixed prescriptions of the boiler, superheater, and turbine parameters, variables such as boiler pressure and temperature can be optimally selected.
