  • Patent number: 11456592
    Abstract: A method manages a fault on a DC voltage side of a converter assembly including a modular multistage converter with switching modules having semiconductor switches and an energy store. Some switching modules are a first type and others are a second type. During operation, a positive switching module voltage, negative switching module voltage or zero voltage are generated at terminals of switching modules of the first type, and a positive switching module voltage or zero voltage are generated at terminals of switching modules of the second type. Upon detecting a DC voltage side fault, switching modules of the first type are actuated such that the polarity of their energy store voltages corresponds to the polarity of a fault current, and energy stores of switching modules of the first type are charged to a voltage exceeding their rated voltage. A converter assembly carrying out the method is also provided.

  • Patent number: 11448236
    Abstract: An outlet guide vane for an axial compressor extending along a rotor axis, includes an airfoil extending in a span direction from a radially inner end at 0% height to a radially outer end at 0% height. The airfoil has a suction side and an opposite pressure side, both sides extending in a chord direction from a leading edge to a trailing edge, wherein for each profile of the airfoil a stagger angle between the chord and the rotor axis is defined. A more favorable air flow profile behind the outlet guide vane is achieved by a new shape of the outlet guide vane, wherein a stagger angle distribution in the span direction has a curved course having a minimum located between 40% and 60% in the span direction, a first maximum at 0% and a second maximum at 100% in the span direction.

  • Patent number: 11442085
    Abstract: A method for monitoring an operating state of an energy supply network connects a data processing cloud to selected communication units at a query time over long-range communication connections. Selected communication units transmit measured values and/or values derived therefrom to the data processing cloud over a long-range connection. To receive measured values and/or values derived therefrom, each communication unit is connected, over a short-range communication connection, to at least one sensor on or in a high-voltage device of the network for capturing measured values. The data processing cloud determines the network operating state within an analysis based on measured values and/or values derived therefrom. To provide a simple and cost-effective analysis of the entire network operating state, the data processing cloud during analysis uses measured values and/or values derived therefrom from at least two selected communication units at different locations.
