| 摘 要： | 采用定电压跟踪器（CVT）的光伏水泵系统在不同地区已成功地投入实际应用。实地运行数据表明，CVT不能适应太阳电池阵列伏安特性的变化，使系统瞬态工作点偏离阵列输出最大功率点，导致系统功率损失。该文报道了2.5kWp，光伏水泵系统的基本构成和典型实地运行数据，并对系统瞬态工作点特性进行了分析讨论。

| Abstract: | Photovoltaic (PV) water pumping systems equipped with constant voltage tracker (CVT) have been put into practice use in different regions. The operating data on the spot for the system show that CVT cannot adapt to the changes of PV array I-V characteristic that depends on solar radiation and temperature. CVT results in deviating working point of the system from maximal power point of PV array, which leads to loss of output power. In this paper, the basic structure and typical operating data of 2.5kWp CVT PV water pumping system are presented. Based on the data on the spot in a typical summer day, the characteristic of instantaneous working point of the system is described. |
