摘要
以青海省刚察县扎苏合10 MW光伏发电工程为例,对比了光伏电站固定支架和固定可调支架（包括月调式、季调式和半年调式）对电站发电效益的影响。结果表明：月调式安装方式的年发电量最高,比固定式高6.31%,月调式的倾角调整范围为4°-66°;季调式安装方式的年发电量比固定式高5.15%,倾角调整范围为10°-62°,春夏秋冬四季太阳能电池板的倾角分别为28°,10°,52°,62°;半年调节方式的年发电量与固定式相比能提高5.07%左右,调整角度分别为58°（冬季与春季）和20°（夏季与秋季）。综合考虑发电效益和不同调节形式支架的复杂程度及对应工作量的大小,半年调式支架更适合作为青海省刚察县扎苏合10 MW光伏发电工程的固定可调式支架方案。
The adjustable fixed bracket is rarely used. Combining the advantages of fixed type and tracing type bracket,the adjustable fixed bracket not only improves the rate of power generation but also reduces the maintenance cost. Taking Zhasuhe 10 MW photovoltaic power station in Gangcha County,Qinghai Province,as an example,the impact on power generation benefit of changing the fixed bracket to be adjustable was compared. The results show that： the annual energy output is 6. 31% higher than the fixed bracket if the angle of the brackets will be adjusted monthly from 4° to 66°; if the brackets are adjusted quarterly,the energy production can be increased 5. 15%,and the angles are 28°,10°,52° and62° for spring,summer,autumn and winter respectively; if the angle between the brackets and horizontal plane is 58°for winter and spring and 20° for summer and autumn,the generating capacity will go up about 5. 07%. Considering the complexity of the brackets and the corresponding work load,the scheme that the brackets angle is adjusted once biannually is proposed for Zhasuhe 10 MW photovoltaic power station.
