Abstract
A method for the closed-loop control of current converters for adjusting the counter-voltage in a multi-phase electric energy transmission network having a multi-phase connection line. In order to be parameterize in various operating states, phase currents are registered on the connection line and transformed into system current components by way of transformation, voltages are registered on the phases of the connection line, and counter-system voltage components are formed therefrom by way of transformation, which are supplied to a voltage controller. Counter-system current components serving to reduce the counter-system are formed in the voltage controller, which are supplied to a target value input of a current controller. System current components are connected to an actual value input of the current controller, the output parameters thereof serving after retransformation as switching currents for switching units of the current converter.
