摘　　要：针对喷灌机季节性用电需求,提出了一种轻小型太阳能平移式喷灌机光伏配置方法,以负载亏电率和能量溢出比为约束指标,以系统全寿命周期成本最小为目标,结合杨凌地区气象资料,对自主研发的太阳能平移式喷灌机驱动行走系统和取水加压系统进行光伏系统的优化配置,得到不同负载亏电率下的供电能量配置组合和全寿命周期成本,并寻求机组光伏阵列最佳布设倾角及系统蓄电池和光伏电池容量的最优配置组合.结果表明:杨凌地区光伏阵列最佳布设倾角为15°左右;太阳能喷灌机阴雨天不灌溉或者少灌溉,配置12块光伏组件和3组蓄电池组,能基本满足作物灌水周期4 d的要求;太阳能喷灌机推广应用时,可适当提高负载亏电率以降低机组造价成本.该方法可用于太阳能平移式喷灌机能量配置系统方案设计和优化,为太阳能在农业机械领域的应用提供参考.Photovohaic （PV） systems have been widely used in agricultural production sector such as water pumps and tractors. Additionally, a solar-powered linear move sprinkler irrigator has been developed for precision agriculture and low energy consumption purpose, but its PV configuration strategy needs to be optimized. A PV system configuration method was put forward in this study according to the seasonal power requirement of sprinkler. Two indexes, namely the loss of power supply probability （LPSP） and the energy excess percentage （EXC） were selected as the constraints, and the minimum cost of life cycle cost （LCC） was specified as data in Yangling, the PV system configurations mal tilt angle of the PV panel is around 15°in the objective function. By means of the meteorological of driving and pumping units were optimized. The opti- Yangling and 12 PV modules and 3 battery groups can meet the power requirement of a 4 - day irrigation cycle. and optimization of linear move sprinkler irrigation, and lar energy in agricultural machinery. This method can be used in PV system design it provides a reference to the application of solar energy in agricultural machinery.
