Abstract

This study investigates a model based on thermodynamic concept to improve the performance of the power block of the concentrated solar power (CSP) systems. The analytical solution of this model established by Aspen HYSYS, Engineering Equation Solver (EES) software programs and Matlab software programming system (Code and Simulink package) to study its performance. The model consists of normal combined cycle (CC), so we studied the efficiency of each component like turbines, compressor, pump, heat exchanger and preheater, at the same time we coupled the CC with storage system to make heat and mechanical stability for the cycle. Decoupled scheme of the power block was developed by adding storage system between the gas cycle and the steam cycle. Then, the performance and the output power of the system were evaluated.
解耦聚光太阳能电站建模
为了提高聚光太阳能发电(CSP)系统的功率块性能,本文研究了基于热力学概念的模型。利用Aspen HYSYS、Engineering Equation Solver (EES)软件程序和Matlab软件编程系统(Code和Simulink包)建立该模型的解析解,研究其性能。该模型由普通的联合循环(CC)组成,因此我们研究了涡轮机、压缩机、泵、换热器和预热器等各部件的效率,同时将CC与存储系统耦合,使循环的热稳定性和机械稳定性得到保证。通过在燃气循环和蒸汽循环之间增加存储系统,提出了动力块的解耦方案。然后,对系统的性能和输出功率进行了评估。
