太阳能与化石燃料互补的评价准则对系统集成开拓与设计优化至关重要,传统热效率、效率等难以科学评估多能源互补特性,不适于作为设计优化目标函数。本文基于热力学基本方程和互补系统特征,提出了太阳能互补收益率的评价准则,体现出与传统燃煤电站热力循环耦合,太阳辐照转功效率的提升程度。应用新准则分析实际光煤互补案例,提出了光煤互补集成原则和方法。该准则简便、合理,为太阳能互补发电的系统集成与优化提供了有效工具。 相似文献

A computer simulation model in ASPEN PLUS shell has been developed to simulate the performance of IGCC and IGHAT cycle power plants. The model was used to study the effects of design and performance parameters on the efficiency and emissions from IGCC and IGHAT cycles. The simulation models are capable of performing mass, energy and exergy balances which may be used to trace system inefficiencies to their source component thereby providing insights into component interactions within the cycles and act as pointers to system optimization trade-offs. 相似文献

An improvement of the energy efficiency ratio of air conditioning systems results when water-to-water dual-mode units are coupled to an aquifer of suitable characteristics which functions as a seasonal thermal storage. The evaluation of the system efficiency from a thermodynamic study is needed, to assess the interactions between the units and the aquifer. A comprehensive thermodynamic analysis is carried out in this paper. A procedure for a numerical evaluation of the system performance and optimization is presented in a convenient form for development and application of the system. A simplified method is also given for preliminary design purposes. 相似文献
