摘　　要：对槽式单轴跟踪控制系统进行研究,结合示范工程的应用效果,分析跟踪控制系统的实用调试方法.推导了太阳相对于聚光跟踪装置的位置计算公式.结合研制的跟踪示范装置对影响跟踪精度的安装位置因素进行了仿真,总结了槽式聚光跟踪精度的校正方法,为大规模的槽式热发电系统的建立和工程化应用提供了参考.Single-axis tracking control system of parabolic trough was studied. Practical debug methods for tracking control were analyzed combined with applications in tracking demonstration plant. Formulas describing the solar varying position relative to concentrating collectors were derived. Associated with the designed demonstration plant, factors which can influence installed position were also simulated with respect to tracking accuracy. Correction methods were given to improve tracking accuracy, which can contributes to supplying mass thermal power generation projects in China as experimental reference.
