摘　　要：由于传统光热电站的集热系统集热效率不高、集控系统预测数据的准确率较低,导致光热电站发电项目并不能大规模地被使用,针对该问题进一步研究了基于数字孪生的光热电站集热集控系统,在此数字孪生的虚拟系统上,搭建了槽式太阳能集热器与集中管控系统的硬件模块,然后根据数字孪生的五维模型设计编写了系统程序代码驱使硬件模块工作。验证了集热器在角度为60°时集热效果最佳,通过集控系统预测的功率数据与实际功率数据的误差对比,证实了该系统集控功能可以稳定运行。Due to the low heat collection efficiency of the collector system of the traditional solar thermal power station and the low accuracy of the prediction data of the centralized control system,the solar thermal power station power generation project cannot be used on a large scale,in view of this problem,the collector centralized control system of the solar thermal power station based on digital twin is further studied,and the hardware module of the trough solar collector and the centralized control system is built on the virtual system of the digital twin,and then the system program code is written according to the five-dimensional model design of the digital twin to drive the hardware module to work.It is verified that the collector has the best heat collection effect when the angle is 60°,and the error comparison between the predicted power data of the centralized control system and the actual power data confirms that the centralized control function of the system can operate stably.
