光热电厂储热系统动态建模及仿真

Dynamic Modeling and Simulation of the Thermal Storage System in Solar Thermal Power Plant

由于太阳能的随机性及波动性,光热电厂在工作过程中其储热系统的工作状态需时常切换。为探究其在不同天气变化情况下的动态特性,本文基于gPROMS建立了光电厂的双罐式储热系统动态模型,并将其运行结果与电厂实际运行结果相比较。仿真结果表明,基于该平台所构建的模型能够在晴天与多云两种天气下准确地描述储热系统的动态过程。

Due to the randomness and volatility of solar energy,solar thermal power plant needs to frequently switch its working condition during its operation.In order to explore the dynamic characteristics of the solar thermal power plant under different weather condition,this paper built a dynamic model of the two tank thermal storage system of a solar thermal power plant based on gPROMS,and the simulation result was compared with the operation result of a real power plant.The result shows that the model built in this paper is able to accurately simulate the dynamic process of the thermal storage system in sunny and cloudy weather.
