摘　　要：针对现有太阳跟踪系统可靠性低,难以满足复杂环境工作的问题,提出了一种应用于复杂环境的高精度太阳跟踪系统,其采用风速、温度、湿度、阳光、限位和时间等传感器,通过信息融合和可靠性设计准则增强了系统的可靠性和鲁棒性;此外,在现有阳光传感器的基础上,设计出一种改进型阳光传感器,消除了现有阳光传感器的不足,提升了太阳跟踪精度。通过在某聚光光伏发电系统中的应用表明,设计的系统跟踪精度优于0.2°,连续工作27 d内未发生故障,表现出良好的鲁棒性、可靠性和一定的智能性。Because of existing solar tracking system has low reliability and can not work in complicated environment, a high-precision solar tracking system with multi-sensors was proposed in this paper for the application of complex environment,whichcontains wind speed sensors, temperature sensors, humidity sensors, solar sensor, limit sensor and time sensor and has good re-liability and robustness by using sensor fusion and reliability design criteria. Besides, based on existing sun sensor, an improvedsolar sensor which eliminates lack of existing solar sensors was designed to enhance the accuracy of the sun tracking. The applica-tion of the system in a photovoltaic power generation system shows tracking accuracy is better than 0.2°,and it continuous work 27days without problems. The system represents good robustness, reliability and intelligent.
