Abstract:
1. A device for operating at least one power generator in an electric power supply network with voltage levels connected through a first and a second transformer, wherein the power generator is connected to a lowest voltage level or to a middle voltage level through a network connection point, the device comprising: a measuring device, which senses a reactive power transfer between two upper voltage levels at the first transformer; a voltage measuring device, which ascertains a voltage at a first network connection point at the lowest voltage level; a computing device, which calculates an amount of a reactive power demand served by the power generator as a function of a voltage value ascertained by the voltage measuring device in order to maintain a voltage ascertained at the lowest voltage level within a predefinable voltage range; and a regulating and control unit, which activates a power supplier for a reactive power draw or a reactive power delivery based on the calculated reactive power demand.
