摘　　要：基于光伏发电扬水蓄能和照明综合应用系统,结合光伏扬水系统构成与运行特点,对太阳辐射强度和输出功率与扬水量特性、光伏水泵系统扬水效率特性及蓄电池储电量占比等进行试验测试.结果表明,定扬程下,光伏泵全天扬水量随日照时间的延长而增大,太阳能平均辐照功率533.4 W,日出水量达13.1 m3,平均每h出水1.93 m3;系统最大扬水效率达12.7%,平均扬水效率11.1%;同时,全天三时段蓄电池充电储能0.47 kWh,约占光伏方阵全天发电量8.4 kWh的5.6%左右.所得结论对光伏扬水系统的配置优化具有一定的实用价值.Based on the comprehensive application system of PV pumping and energy storage and lighting,combining with components and operating characteristics,the tests of solar radiation intensity,output power,water pumping volume,motor-pump system efficiency and lead-acid batteries storage capacity are carried out.Experimental results show that under a certain pump head,the PV pump’s total water volume increases with the extension of sunshine time.When the average daily solar irradiation power is 533.4 W,the daily water yield reaches 13.1 m3,the average water output is 1.93 m3/h,and the high-pumping efficiency is 12.7%,and the average pumping efficiency is 11.1%.At the same time,the lead-acid batteries charge is 0.47 kWh in three periods of whole day,which is about 5.6%of 8.4 kWh total power generation of the solar PV array.It will provide a reference for PV pumping system designing and optimization.
