大人口的光伏逆变器和配电网之间的相互作用的主要机制进行了研究。一些在低压网络中具有大量小型光伏逆变器的示范项目显示出高水平的电压失真，尽管单个光伏逆变器的排放水平满足PQ标准。本文的主要目的是分析大量逆变器的谐波干扰的观察到的现象，并提供一些现有的网络组件和光伏逆变器之间的谐振的解释。这些共振通常可以位于第5和第40谐波数之间。谐振现象进行了研究，使用广泛的实验室实验两个逆变器拓扑结构，以及不同的逆变器拓扑结构和网络仿真研究的Vroonermeer-Zuid网络的计算机建模。
The dominating mechanisms of interaction between large populations of PV inverters and the electrical distribution network are investigated. Some demonstration projects with large number of small PV-inverters in a low voltage network, show high levels of voltage distortion, although the emission level of an individual PV inverter satisfy the PQ standards. The main object of this paper is to analyse the observed phenomena of harmonic interference of large populations of inverters and provide some explanation of the resonance between existing network components and the PV inverters. These resonances may lie typically between the 5th and 40th harmonic number. The resonance phenomenon is investigated using extensive laboratory experiments on two inverter topologies, as well as computer modelling of different inverter topologies and network simulation studies on the Vroonermeer-Zuid network.
