摘　　要：为零缺电率负载供电的独立光伏系统是对设计要求最高的光伏系统,必须慎重地进行优化设计。研究表明,如果采用一般的独立光伏系统优化设计程序来进行设计,只要用蓄电池维持天数等于零代入,即可确定太阳电池方阵的容量,同时可以用当地辐照量最低的月份得到最大辐照量所对应的倾角作为方阵的最佳倾角。确定蓄电池容量时应以当地最长连阴雨天数作为蓄电池维持天数的依据。通过实例分析,取得了良好的效果。Stand-alone photovoltaic system for zero LOLP is tiptop demanding PV system, and optimum sizing should be carefully considered. Research shows capacity of photovoltaic array can be confirmed, if generic program of optimum sizing stand-alone photovoltaic systems is adopted, and using days of storage of batteries equal to zero, at the same time the tilted angle with yields of the highest value of radiation in the month with the lowest radiation is considered as the optimum tilted angle. In determining capacity of battery, the days of storage should be the longest no - sun days. After example analysis, favorable effect can be obtained.
