    摘要： Electrical malfunctions in a network which are caused by torque fluctuations of an electric motor, in particular flicker, are reduced by using a control device. For simple and cost-effective minimizing or even correction of such malfunctions with the control device, the control device has at least one first input for supplying an input signal which contains information suitable for determining the loading of the network by torque fluctuations and at least one output for transmitting an output signal to at least one converter supplying the electric motor. This makes it possible to reduce or ideally to eliminate electrical malfunctions in a network which are caused by torque fluctuation of the electric motor.

    摘要： A system for generating a duty cycle control signal for controlling an inverter power train providing an output current waveform to a grid operating with a grid voltage waveform compares a reference current waveform shaped to the grid voltage waveform with the output current waveform to generate an error signal. The error signal is used to generate a corrective control action signal, which is combined with a feed-forward signal representing a nominal duty cycle generated with a feed-forward function. The combination of the feed-forward signal and the corrective control action signal provide the duty cycle control signal.

    摘要： In order to provide a method for regulating a reactive power compensator, which is connected to an alternating current line having multiple phases, wherein for each phase an actual voltage V12, V23 and V31 present thereon is detected and from the actual voltages V12, V23 and V31 a counter system actual fraction is calculated. A control circuit suppresses the counter system actual fraction. A feedback loop determines the level of suppression of the counter system actual fraction with the help of controlled parameters. The method enables an adjustment of the counter system that is largely independent from operating staff. Accordingly, a comparator unit compares the counter system actual fraction to the counter system target fraction and defines the controlled parameters as a function of the comparison.

    摘要： An electric network for generation and transmission of electric power, including a power generating part, a point of common connection for the power generating part, a transmission link, a load network, and a reactive power compensator. The transmission link is coupled between the point of common connection and a grid connection point at the load network. The reactive power compensator is coupled to transmission link. The power generating part includes at least one wind turbine with an electric generator of induction type, coupled to the point of common connection. The reactive power compensator includes a capacitor bank and in parallel coupling to the capacitor bank a controllable inductor having a magnetic core, a main winding for alternating current, and a DC-control winding for direct current. The DC-control winding for control of the magnetic flux is set up by the main winding via orthogonal magnetization of the core.
