METHOD FOR CONTROLLING CURRENT CONVERTERS AND ASSEMBLY FOR PERFORMING SAID METHOD

摘要

The invention relates to a method for controlling current converters for adjusting the counter-voltage in a multi-phase electric energy transmission network (1) having a multi-phase connection line (2). In order to be able to relatively simply perform a parameterization in various operating states in such a method, phase currents are registered on the connection line (2) and transformed into system current components by means of transformation, voltages are registered on the phases of the connection line (2), and counter-system voltage components are formed therefrom by means 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 (17), which are supplied to a target value input (28) of a current controller (9). System current components are connected to an actual value input (8) of the current controller (9), the output parameters thereof serving after retransformation as switching currents for switching units of the current converter. The invention furthermore relates to an assembly for performing said method.
