摘要
在碟式太阳能系统的长期实验数据中发现,太阳辐照度较低时系统集热效率非常低。为使碟式太阳能系统始终运行在高集热效率状态,提出模糊推理方法改进跟踪系统的启停判定条件,并根据集热器出口气流温度的影响因素建立模糊推理系统。仿真结果表明模糊系统在已知太阳辐照度、辐照变化度和空气流量的前提下,可智能控制系统在集热效率高时运行,集热效率低时待机,证明了该方法的可行性和有效性。
In the long-term experimental data of dish solar system,it is found that the heat collection efficiency of the system is very low when the solar irradiance is low. In order to keep the dish solar system running in the state of high heat collection efficiency,a fuzzy reasoning method is proposed to improve the starting and stopping judgment conditions of the tracking system. The simulation results show that the fuzzy system can make the system operate intelligently when the heat collection efficiency is high and standby when the efficiency is low.
