Abstract
A method and apparatus for controlling a neutral point voltage of a three-phase resonant-earthed electric network, the apparatus including determining means configured to determine a target value for the neutral point voltage of the three-phase resonant-earthed electric network, calculating means configured to calculate at least one phase-specific control admittance or a neutral point specific control admittance required for controlling the neutral point voltage of the three-phase resonant-earthed electric network from a prevailing value to the determined target value, and admittance means configured to add the calculated at least one phase-specific control admittance between a ground and a respective phase of the three-phase resonant-earthed electric network or the calculated neutral point specific control admittance between the ground and a neutral point of the three-phase resonant-earthed electric network.
