【摘要】 为提高太阳能发电装置的太阳能利用率及输出功率，以槽式太阳能温差发电装置为研究对象，设计一种以PLC为控制器，MCGS触摸屏为组态界面的跟踪控制系统。该系统通过光照度传感器反馈信息，步进电机控制聚光镜，使得聚光镜绕南北东西两侧旋转跟踪太阳的高度角和方位角，以此提高太阳能发电装置的光电转换效率。为验证槽式太阳能温差发电装置跟踪控制系统的可行性，对装置的发电量进行测量，试验结果表明：装置连续10天给日光温室负载供电，总发电时间为52.01h，共发电2.74kW·h，可满足日光温室育苗的日常用电。装置结构灵活，可通过增加串并混合连接温差发电片的数目，进一步提高该装置的发电量。更多还原

【Abstract】 In order to improve the solar energy utilization rate and output power of the solar power generation device,this paper takes the parabolic trough thermoelectric generation device as the research object,it proposes a new type of solar power generation device,which uses PLC as the controller and MCGS touch screen as the configuration interface.Through the feedback information of the illumination sensor,the step motor controls the concentrator,so that the condenser rotates around the north,south,east and west sides to track the sun’s height angle and azimuth angle,so as to improve the photoelectric conversion efficiency of the solar power generation device.In order to verify the feasibility of the tracking control system of the trough type solar thermal power generation device,the power generation capacity of the device was measured.The test results showed that the device supplied power to the load of the solar greenhouse for 10consecutive days,the total power generation time was 52.01h,and the total power generation was 2.74kW·h,which could meet the daily power consumption of the solar greenhouse seedlings.The structure of the device is flexible,and the power generation of the device can be further improved by increasing the number of series parallel hybrid connected thermoelectric generators.更多还原
