摘要
为促进太阳跟踪装置的推广应用,降低光伏发电成本,研究了目前太阳跟踪装置的主要跟踪方式、布置方式和结构特点、控制和驱动方式,比较了不同跟踪技术的能量收益,说明了单轴和双轴跟踪的适用范围。利用太阳跟踪技术可以显著提高光伏系统的电能收益,为了早日实现光伏电能平价上网,有必要因地制宜地推广太阳跟踪技术。
In order to promote spread and application of solar tracing system and low cost of photovoltaic generation, main tracing modes, configuration mode, structure, control and driving means of present solar tracing system are studied, energy profit of different tracing techniques is compared and applicability of single-axis and two-axis tracing are expounded. The use of solar tracing technique can greatly improve electric energy profit of photovoltaic generation. It is necessary to extend so- lar tracing technique in accordance to local conditions to make photovoltaic generated electric power at standard price.
