    摘要: A closed-loop control method for at least two converters in an energy transmission and/or distribution system. The converters may be controlled either as rectifier or inverter and they are connected to each other by a DC link. A measured DC voltage and a measured DC current is measured at each converter and transmitted to a rectifier regulator for regulating the corresponding rectifier or to an inverter regulator for regulating the corresponding inverter. Each rectifier regulator and each inverter regulator gives the difference between a given set DC voltage and the relevant received measured DC voltage to give a differential DC voltage and the difference between a set DC current and the corresponding received measured DC current to give a differential DC current. The measured DC current, the measured DC voltage, the set DC current and the set DC voltage are normalized with which a regulation of inverters formed of switchable power semiconductors connected by a DC link can be carried out, wherein the proviso of set currents being zero is possible. Each converter is a self-commutated converter with power semiconductors and the rectifier regulation of the provided converter is regulated such that the sum of the product of the differential voltages and the value of given set DC current at the corresponding rectifier and the differential current is a minimum and the inverter regulation regulates the corresponding inverter such that the sum between the differential voltage and the differential current is a minimum.

    摘要: A converter has at least one phase module, an AC voltage terminal and a DC voltage terminal. A phase module branch is formed between each DC voltage terminal and each AC voltage terminal. Each phase module branch has a series circuit containing submodules which each have a capacitor, a power semiconductor, and submodule sensors for detecting energy stored in the capacitor and with a regulation device for regulating the apparatus in dependence on energy values and predetermined desired values. Therefore unbalanced loading of the energy storage units is avoided. The regulation device has a summation unit for summing the energy values while obtaining branch energy actual values and a device for calculating circuit current desired values in dependence on the branch energy actual values. The regulation device compensates for imbalances in the branch energy actual values in dependence on the circuit current desired values.
