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： In the method for closed-loop control of at least two converters in an energy transmission and/or distribution system, each rectifier regulator and each inverter regulator provides a differential DC voltage from the difference between a given set DC voltage and the relevant received measured DC voltage, and also provides a differential DC current from a differential DC current from the difference between a set DC current and the corresponding received measured DC current. Each converter is a self-commutated converter with power semiconductors. 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. 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 control device for rectifier stations in a high-voltage DC transmission system has a rectifier drive unit and an inverter drive unit for driving power rectifier stations that are working either as a rectifier or as an inverter. The trigger angles for the rectifier or for the inverter can be adjusted and regulated by way of the rectifier drive unit and the inverter drive unit respectively. A delay element is placed between the rectifier drive unit and the inverter drive unit with which the start time for regulating the trigger angle for the inverter relative to the start time for regulating the trigger angle for the rectifier can be delayed by a predetermined delay time. Because of less mutual interaction of the trigger angle control processes, a relatively faster transition from an initial operating state into a new stationary state results.

摘要： A device for damping control of mechanical torsional oscillations of an electrical alternating current generator connected to a multi-phase power supply system, includes a controllable converter of an HVDC installation connected to the power supply system, a measurement and filter device for detection of a frequency-dependent signal in a frequency range of the torsional oscillations of the alternating current generator and a correction apparatus for correction of a control signal for the converter for the HVDC installation. The correction apparatus includes a single phase correction filter for correction of a phase frequency response of the frequency-dependent signal. The control signal is formed by a current nominal value of a current regulator of the converter or a triggering angle of the nominal valve and with the phase correction filter is configured to take a transfer function of the current regulator into account.

摘要： An apparatus for controlling a converter has an ignition unit connected to power semiconductors in the converter and provides control signals for actuating the semiconductors. The apparatus has a control unit whose input is connected to measuring sensors providing actual values and whose output side is connected to the ignition unit. The control unit provides a reference variable for the ignition unit based on setpoint values and the actual values and the ignition unit actuates the power semiconductors such that the actual value corresponds to at least one of the setpoint values. A pilot unit has an output connected to the ignition unit and measures for calculating a step change reference variable for the ignition unit on the basis of at least one of the setpoint values. The ignition unit actuates the power semiconductors based on the step change reference variable.
