摘要

摘要: 基于传热学、热力学、动力学、电学理论以及系统控制模型,建立了可用于碟式斯特林发电系统分析、设计、优化和控制的性能分析模型.模型包括太阳能聚光器、接收器、斯特林循环热力学、斯特林发动机机构动力学、起动/发电机等各子系统及相互作用关系,可分析系统从起动到全功率状态时的稳态性能和动态特性.使用该模型对碟式斯特林系统进行了仿真分析,结果表明,在发动机热端温度不变的控制条件下,系统一天内的输出电功率表现出与太阳直射强度类似的抛物形变化,系统效率变化较平稳;系统充气过程压力突增,在太阳直射强度不变的情况下,发动机热端温度下降,发电功率先增加一点,后随温度下降而下降.

Abstract: A solar dish-Stirling system model was developed for design, optimization, control, and systems development of dish-Stirling systems. It modeled the energy transfer in parabolic concentrator and receiver, cycle thermodynamics and mechanical dynamics in Stirling engine and so on. The model's scope extends from the solar energy to thermal, mechanical, and electrical energy out, helping to study complex system interactions among subsystems. It can be used to simulate the entire range of system operation from start-up to full power conditions. The model details were discussed and the simulation results were given for steady and dynamic phenomena. According to the constant hot-end temperature control strategy, the system output power changes parabolicly with the direct normal insolation and the system efficiency changes slightly in a day. During the feeding process which causing a pressure jump, the hot-end temperature decreases in case of engine speed unchanged, and the output power increases firstly and then decreases to a steady value.
