Abstract In photovoltaic (PV) power stations, a large number of photovoltaic inverters working under the “weak network” are more likely to motivate harmonic resonance with the power grid, which threatens the power supply continuity and operation safety of the power station. In this paper, based on a real PV substation, the harmonic equivalent model of the traditional PV power station is established which considers the variation of the network impedance of the upstream of the grid, and the resonance is analyzed. On this basis, considering the real harmonic resonance in the traditional PV power station, this paper proposes a harmonic resonance damping method of PV power station based on inductive filtering. The harmonic model and resonance suppression mechanism are analyzed in detail. In this method, the filtering winding of the inductive filtering transformer (IFT) adopts a special zero impedance design, which is externally connected with a fully tuned passive filter (PF). It can obtain better harmonic filtering ability. At the same time, it can effectively eliminate the harmonic resonance of PV power station in the traditional PV power station by changing the impedance frequency characteristics of the whole network of PV power station. Finally, through the simulation and the measured data of the large engineering application, the excellent characteristics of the new method is verified.

Key words： Photovoltaic power station equivalent model inductive filtering resonance suppression
