摘要
水泵电机型号、种类的匹配和光伏阵列的选择,对整个光伏水泵系统的性能有很大影响。针对传统光伏水泵实验系统中存在的测量数据不准确、效率低下、受外部环境影响大、无法进行有效控制等缺陷,研发了一种基于LabVIEW的光伏水泵实验控制系统。该系统利用数据采集控制装置对实验的各环节进行监控,同时采用计算机模拟光照条件,有效地减少了外部条件的制约。实验系统使用LabVIEW来处理数据,通过完整的系统软件平台来控制水泵电机的运行,使整个实验更加高效、快速。实践结果表明经过该实验系统选型的光伏水泵和光伏阵列能显著提高抽水效率。
The matching of photovohaic pump models and types, and photovoltaic arrays greatly affects the performance of the entire photovohaic pumping systems. Some improvements are needed on the conventional photovoltaic pumping experimental systems, such as inaccurate measured data, low efficiency, easy affection of external environment. A new type of photovohaic pump experimental control system based on LabVIEW was developed to achieve the goal. This system monitored and controlled various aspects of the experiment by data acquisition and control devices. Meanwhile, the computer was connected to simulate the sunlight condition so that the whole system can work perfectly in any environmental conditions. Data was handled by LabVIEW and the pump motor was controlled by the integrated system software platform. Experiment proves that the new system makes the whole experiment more efficient. The results indicate, the efficiency of pumping water is greatly improved because of the photovoltaic pumps and photovoltaic arrays selected by this experimental system.
