摘要： The invention relates to a method for damping electromechanical oscillations in an electromechanical system (50), particularly in an automotive electric or hybrid drive system, comprising at least one electric machine (20) operable with an angular speed (ω el, ω mech) and a phase of said angular speed (ω_el, ω mech), being coupled to at least one torque load (40) and producing an electromotive force (emf ff). The method comprises the steps of (i) deriving actual values of the electromotive force (emf_ff) and (ii) adjusting the phase of the angular speed (ω_el, ω_mech), based on the derived actual values of the electromotive force (emf ff), in a direction in which an oscillatory behaviour of said electric machine (20) is reduced.

摘要： The present invention is concerned with the combined voltage or power flow control and damping of electromechanical oscillations in an electric power system (2) by Flexible AC Transmission System (FACTS) devices (20) or High Voltage DC (HVDC) transmission devices. To this end, information about a state or operating point of the power system is generated from suitable second system signals (y 2 ) and a control parameter (cp) of a FACTS controller (1) is derived therefrom. The control parameter and a first system signal (y 1 ) are used in the calculation of a control command (u) defining the settings of the FACTS device. Following a change in the state of the power system such as a change in the topology of a transmission network, poorly damped or even unstable oscillations are avoided by appropriate re-tuning of the control parameter of the damping or stabilizing equipment.

摘要： In an apparatus for converting alternating voltage to direct voltage and conversely with a series connection of at least four units (1-4) each comprising a semiconductor device (10-13) of turn-off type and a diode (14-17) connected in anti-parallel therewith between two poles of a diode voltage side, a flying capacitor (25) is connected between two outer midpoints (24, 26) between two units of the series connection, while the midpoint of the series connection is connected to an alternating voltage phase line (19). An arrangement (27) is adapted to control the units (1-4) for transferring the apparatus between a main operation mode and an alternative operation mode depending upon function parameters of the apparatus. The semiconductor devices of the outer units (1, 4) are then kept continuously turned on in the alternative operation mode and only semiconductor devices of the inner units (2, 3) are then switched. The control arrangement (27) controls the voltage of the pulses on the phase output (18) of the apparatus to be lower in the alternative operation mode.
