Verfahren zum Regeln der Spannung an Abgabestellen in einem elektrischen Energieverteilungsnetz

摘要

The invention relates to a method for regulating the voltage at which electric energy is supplied at the delivery points in a network for distributing electricity. The voltage of electric energy supplied through a high-voltage network is reduced to a voltage suitable for a medium-voltage network by means of at least one variable transformer. The voltage of the electric energy in the medium-voltage network is reduced, by means of at least one transformer, to a voltage suitable for a low-voltage network supplying the electric energy to the consumers. The adjustment of the variable transformer between a high-voltage network and a medium-voltage network is influenced by the actual voltage measured and the current or load at the output side of the variable transformer. The voltage prevailing at the delivery point is measured at the location of at least a number of consumers and the variable transformer is set partly in dependence on the voltage thus measured at the consumers' location.
