摘要/Abstract

摘要： 针对传统槽式太阳能追踪控制系统跟踪精度较低导致的太阳能利用效率降低的问题，设计一种槽式光热太阳能追踪控制系统。基于太阳位置算法（solar position algorithm，SPA）建立槽式光热单轴追踪数学模型，研究聚光器布置方式对系统运行特性的影响。搭建样机试验系统，基于可编程逻辑控制器（programmable logic controller，PLC）设计跟踪控制逻辑，通过自定义嵌入式编程实现高精度算法在控制器中的应用。提出一种根据跟踪角偏差运算进行间歇控制的策略，使用中高压双液压缸推挽式驱动方式推动集热槽旋转，实时跟踪太阳位置。阐述PLC控制系统软硬件架构、功能模块及控制流程，采用控制器双机冗余配置及监控双网配置。运行数据表明：系统结构简单，维护方便，跟踪精度较高。

Abstract: A novel parabolic sun-tracking system is proposed, in response to inefficiency of solar energy utilization due to the low tracking accuracy of sun-tracking system for parabolic trough solar concentrator. The mathematical model of trough photothermal single-axis tracking is established based on solar position algorithm (SPA) and the influence of different arrangements on the operation characteristics of the system is studied. The prototype test system is built and the tracking control logic is developed based on programmable logic controller (PLC). The application of high-precision algorithms in the PLC controller is realized through custom embedded programming. A strategy of intermittent control based on deviation of tracking angle is proposed. The push-pull drive mechanism with dual hydraulic cylinder and medium and high pressure is utilized to drive the trough concentrator with the purpose of real-time tracking of the solar position. The hardware and software architecture, main function modules and control flow of PLC control system are expounded. Besides, redundancy configuration of the controller and monitoring network are adopted. Operating data shows that the system has features of simple system structure, convenient maintenance and high tracking accuracy.
