Endura Posted October 5, 2022 Share Posted October 5, 2022 Does the Power Factor setting directly correlate to the Inverter Pnom limit or is it adjusted based on line losses & transformer losses as well? For greater clarity: Transformers and conductor systems (primarily long MV systems) change reactive power consumption within a PV plant so an inverter power factor setting would vary from the point of interconnection's Power Factor depending on the requirement (leading or lagging) and equipment/design of the PV plant. For performance modelling in PVsyst, should we be performing this load flow analysis externally and setting the Power Factor in PVsyst based on the requirement at the inverter? Or does PVsyst perform some adjustments to account for reactive power within the PV plant? For example, we have a plant with a long MV interconnection where the power factor at the grid point is 95% but the power factor at the inverter may be as low as 91% to deliver that PF to the grid. In this case, would the recommendation be to use 91% in PVsyst or 95%? Link to comment Share on other sites More sharing options...
