| 摘要: |
| 为了减少光伏电站的发电量损失，最大可能避免倒塌、热斑损坏、自然老化率过快等现象，利用自然法则，提出一种新颖的方法以实现对光伏组件的全面智能管理。该方法采用晶体硅本身的光伏I-V特性，通过自然法则原理，获得组件的理论功率输出与实际功率输出的对比数据，以此来判断光伏组件是否正常。试验表明，此方法效果良好，完全满足电站光伏组件功率输出的精度要求，可以有效实现大中型光伏电站的组件的全面智能管理。 |

| Abstract: |
| In order to reduce the power loss of photovoltaic plants and to avoid utmostly the phenomena of collapse, hot spot damage and too fast natural aging rate, a new method is proposed by using the law of nature to realize a comprehensive intelligent management of PV modules. This method uses the I-V character of crystalline silicon and the law of nature to achieve the data of capacity output in theory and in reality, respectively, and then to estimate whether the PV modules are regular. Some experiments show that this method is good enough to fully meet the requirement of the accuracy of capacity output of PV modules and to effectively realize the comprehensive intelligent management of PV modules of large and medium-sized photovoltaic plants. |
