摘要/Abstract

摘要：

太阳能接收器是塔式太阳能电站的重要组成部分,是光热转换的重要部件,因此接收器的建模和仿真对实现电站的平稳运行具有重要意义。根据能量守恒、质量守恒定律,对以美国Solar Two电站接收器为原型的高温熔盐接收器吸热管进行空间离散化,建立了接收器分段集总参数模型。模型稳态仿真结果与Solar Two电站接收器测试结果的对比验证了模型的正确性。通过接收器动态仿真,分析了输入变化和接收器接收能量不均匀时的传热特性,可为定日镜场聚焦策略以及电站安全运行的研究提供依据。

关键词: 太阳能, 接收器, 分段集总参数模型, 动态建模, 动态仿真

Abstract:

The receiver is an important part for photothermal conversion in the solar tower power station. Thus, modeling and simulation of the receiver is extremely significant for the safety and steady-operation of the plant. The sectional lumped parameter model of the molten salt receiver, whose prototype is Solar Two located in USA, is established by the space discretization of the heat tubes according to the law of conservation of energy and mass. The validity of the model is verified through the comparisons between the test results of the receiver in Solar Two plant and the simulation results. The heat transfer characteristics of the receiver in the cases where the inputs change and the received energy distribution isn't uniform are analyzed by the transient simulation, which can provide the foundation for the investigation of the aiming points strategy and safe operation of the station.

Key words: solar energy, receiver, sectional lumped parameter model, dynamic modeling, dynamic simulation
