太阳能光伏并网控制逆变器工作原理及控制方法

发布日期:2020-01-23 作者: 点击:

光伏电池的理想模型可由下式表示:

大发体育QIZHONG,vtWEIDIANCHIBANREDIANSHI。

图3表述在特定光照条件下电池板的伏安特性。阴影部分是电池板在相应条件下所能够输出的最大功率。光伏发电厂家太阳能电池板在高输出电压区域,具有低内阻特性,可以视为一系列不同等级的电压源;在低输出电压区域内,该电源有高内阻特性,可以视为不同等级的电流源。电压源与电流源的交汇处便是电池板在相应条件下的最大输出功率。光伏发电厂家在电池板的温度保持不变的情况下,这个极大功率值会随着光照强度的变化而变化,最大功率跟踪要求能够自动跟踪电池板的工作在输出功率极大的条件。
