Reactive power compensation in a threephase power supply system in an electric vehicle charging station
Abstract
The article presents the problem of reactive power compensation in an electric network, which powers a charging station for electric vehicles. The reactive power is present because the converters have a reactance character. Mobile inverters are single-phase receivers, so they cause a lack of symmetry in a three-phase system. Lack of symmetry causes an unbalance component to appear. The power compensation discussed here results in an improvement in the power factor. The reduction of the reactive and unbalance power is the result of this compensation. The article takes into account a non-sinusoidal method of power supply.
