Effect of the Condenser Pressure and Normalized Steam Mass Flow Rate on the Normalized Net Work Output of the Solar Power Plants

The growing problem of global warming and environmental pollution has become an urgent necessity in order to avoid these dangers and to solve these problems it is necessary to expand the use of solar power stations., in this study was conducted simulations for solar power plant with parabolic trough concentrates, and the study focused on the effect of pressure and mass flow rate of steam which is generated in the solar field, on the work, which is produced in the power plant in general. A comprehensive model for the simulation of a regenerative Rankine cycle was developed. The results obtained showed that the output power from the cycles is affected mainly by: the inlet heat transfer fluid (HTF) temperature, mass flow rate of the HTF and the condenser pressure. The cycle parameters were normalized and it was found that the performance was independent of the power block size. A linear regression was proposed by using the normalized variables, the results showed that the linear equation represents accurately the trend given by the results obtained in the simulation
