| 摘 要： | 蓄热系统是太阳能热发电站中保证电站可靠性和经济性的重要组成部分,其工作状况直接影响到太阳能热发电站的正常运行。本文针对单罐式蓄热系统,分析了系统在蓄热和放热模式下的动态数学模型,在此基础上,提出了蓄热系统的混杂动态系统模型。该模型将蓄热和放热模式统一在一个框架下,能够对蓄热系统的各种操作模式及其循环交替过程进行动态模拟。混杂模型采用MATLAB软件进行仿真,仿真结果:表明了模型的有效性。

| Abstract: | The heat storage system has been considered as an important component of a Solar Thermal Power Plant to ensure plant reliability and economic profitability.Its working conditions directly affect the normal operation of solar thermal power plant.The dynamic model of a single tank thermocline storage system is discussed in this paper.Dynamic mathematical model of the storage system in heat charging and discharging process is analyzed.A new hybrid model is proposed based on the characteristics of the heat charging and discharging processes. The heat charging and discharging processes are integrated in a uniform model.The proposed model is applicable in simulating various operational conditions and their frequent switch in the storage system.The hybrid model is simulated on MATLAB Software,and the simulation results demonstrated the effectiveness of the model. |
