  • METHOD AND DEVICE FOR CONTROLLING AN ELECTRIC VOLTAGE
    Publication number: 20210028624
    Abstract: A method and a device control a voltage of a power grid by use of a reactive power device connected to the power grid. The method includes: determining a change over time of a previous voltage of the power grid, determining a change over time of a reactive power previously output into the power grid by the reactive power device, and subsequently outputting reactive power into the power grid by the reactive power device, which reactive power is determined in dependence on the changes over time.

  • DC compensation for high DC current in transformer
    Patent number: 10032556
    Abstract: A system for compensating one or more DC components in an electrical system includes one or more sensors for sensing the one or more DC components. The system also includes one or more DC component controllers for generating one or more reference signals from one or more signals received from the one or more sensors. In addition to this, the system also has one or more controllers for generating one or more firing pulses from the one or more reference signals received from the one or more DC component controllers and one or more valve configurations for charging one or more controllable branches to counterbalance the one or more DC components of the electrical system. A method for compensating one or more DC components in an electrical system is also provided.
