太阳能利用中的阳光跟随系统研制

Development of sunlight tracking system in solar energy utilization

设计一款可用于大多数太阳能利用场合的阳光跟随系统.由于采用普通光敏电阻作为传感器并基本免去电路中的模拟放大电路部分,可提高系统的抗干扰性和可靠性,延长维护周期.同时大幅度降低了成本,使得太阳能利用系统中每路太阳能光伏电池板对日光进行独立跟踪成为可能,可进一步提高系统效率.在伺服方面采用步进电机加蜗杆减速装置,保证系统在机械角度维持方面无需额外的控制和能源.

A sunlight follow system of solar energy utilization was developed. As a result of using com- mon photosensitive resistance as the sensor and rarely using the analog amplifying circuit, the reliabili- ty of this system is improved. The maintenance cycle is extended and the cost is reduced. By this way, each solar photovohaic panels tracking sunlight independendy in this system becomes possible, so as to improve the efficiency of the system. In servo unit, stepping motor and worm reducer was used to keepthe mechanical angle without additional control and energy.
