一种光伏发电组件优化监控方法和系统
摘要：
本发明公开了一种光伏发电组件优化监控方法和系统，包括获取光伏组件参数，计算能够表示老化程度的填充因子；判断填充因子是否超过预设的阈值；根据判断结果，若超过则该光伏组件老化程度严重，若没有超过则该光伏组件短路或轻微老化。因此，所述光伏发电组件优化监控方法和系统能够实现对光伏组件工作状态的监测和诊断。
摘要（英）：

The invention discloses a photovoltaic electricity generating assembly optimized monitoring method and a photovoltaic electricity generating assembly optimized monitoring system. The method comprises the following steps of obtaining a photovoltaic assembly parameter; calculating a filling factor capable of expressing the aging degree; and judging whether the filling factor exceeds a preset threshold or not. According to the judging result, the aging degree of the photovoltaic assembly is serious if the filling factor exceeds the preset threshold; and the photovoltaic assembly is in a short-circuit state or the aging degree is slight if the filling factor does not exceed the preset threshold. Therefore the photovoltaic electricity generating assembly optimized monitoring method and the photovoltaic electricity generating assembly optimized monitoring system can realize the monitoring and the diagnosis on the work state of the photovoltaic assembly.
