The distributed photovoltaic power station

after connection to the power grid

causes reduction of the power factor of the gateway. It is found through the actual case investigation that the reasons for the reduction of the power factor are not exactly the same. It is related to the location of the grid-connected point

photovoltaic installation capacity

actual load

type of reactive power compensation

reactive power compensation capacity distribution

sampling point location of reactive power compensation

harmonic protection configuration

etc. Through analysis and calculation

the specific effective solutions are proposed for different reasons.
