| 摘 要： | 为了能够优化配置光伏提水工程中的光伏功率和水泵功率,分析了控制逆变器的转换效率、导线带来的损失、光伏阵列的实际最大输出功率等影响因素,推算出在云南省绝大部分地区光伏功率和水泵功率之比的优化取值范围应在1.31.6之间.对一个功率比为1.3左右的光伏提水工程的测量表明,在晴天中午时分,该工程的水泵工作在其额定功率的90%左右,验证了该优化取值范围是有效的. |

| Abstract: | In order to optimally configure photovoltaic power and pump power in a photovoltaic pumping engineering,the impact factors of photovoltaic pump systems are analyzedin detail in this paper,including the efficiency of control inverters,the wire-induced loss and the real maximum output power of photovoltaic arrays,then a deduction is made that the optimum value of the ratio of photovoltaic power to pump power in a photovoltaic pumping system should be between 1. 3 and 1. 6 in most areas of Yunnan province. Measurement results indicate that at noon of a fine day,the pump works at 90 percent of its rated power in a photovoltaic pumping engineering with a power ratio of 1. 3. This proves the optimum value of the power ratio is effective. |
