摘要
为提高太阳能利用效率,提出一种基于发电机组冷凝器余热利用的塔式太阳能热发电站太阳能热电联供系统。依据延庆太阳能热发电站的构成,搭建太阳能热电联供瞬态模型及仿真软件,并进行实验验证。利用仿真软件对延庆电站的热电联供系统进行模拟和系统性能研究。
In order to improve utilization efficiency of solar energy,a kind of solar cogeneration system with absorption heat pump based on Solar Thermal Power(STP)tower plant is presented in this paper.The 1 MW STP tower plant in Beijing serves as a case study to analyze the proposed system.With mathematical models of each component,simulation platform of the proposed system is developed under TRNSYS application environment.The dynamic performance is simulated at ten minute intervals during the whole heating season.The simulation results show that the proposed system can guarantee continuous heating for consumers.Attributed with the contributions of the regenerative cycle,the power generation in the proposed system is also effectively improved.Comparing with the original STP tower plant,the overall energy efficiency of the proposed system is increased from 11.26%to 14.67%.
