    Abstract: Active impedance-injection module enabled for distributed power flow control of high-voltage (HV) transmission lines is disclosed. The module uses transformers with multi-turn primary windings, series-connected to high-voltage power lines, to dynamically control power flow on those power lines. The insertion of the transformer multi-turn primary is by cutting the line and splicing the two ends of the winding to the ends of the cut high-voltage transmission line. The secondary winding of the transformer is connected to a control circuit and a converter/inverter circuit that is able to generate inductive and capacitive impedance based on the status of the transmission line. The module operates by extracting power from the HV transmission line with the module floating at the HV transmission-line potential. High-voltage insulators are typically used to suspend the module from transmission towers, or intermediate support structures. It may also be directly suspended from the HV transmission line.

    Abstract: A power supply is described herein which provides power to a load, such as a load including one or more computing devices. The power supply uses a slow-response power source (such as a fuel-driven mechanism) to handle a slow-moving component of the demand level presented by the load, and uses a fast-response power source (such as a battery or a capacitor, etc.) to handle a fast-moving component of the demand level. By virtue of this approach, the power supply can manage the load level as it appears to the slow-response power source, allowing, in turn, the slow-response power source to service even fast-changing loads—a task which it could not otherwise perform due to its native limitations.

  • Patent number: 9893561
    Abstract: A power supply conversion system receives an external power source to supply power to a load. The power supply conversion system includes at least one main power apparatus, at least one auxiliary power apparatus, a main switch, an auxiliary switch, and a control unit. The control unit turns on the main switch to restore the external power source when the control unit detects that the external power source is normally restored, and jointly supply power to the load with the auxiliary power apparatus. Especially, the output voltage of the main power apparatus is greater than the output voltage of the auxiliary power apparatus. In addition, the control unit disconnects the auxiliary power apparatus supplying power to the load when the control unit detects that the main power apparatus completely supplies power to the load.

    Abstract: A method for controlling an electrical energy distribution network in which electrical power is provided via network nodes connected via power lines is provided. A portion of the network nodes are controllable network nodes with respective local controllers, and at least a portion of the controllable network nodes are energy generators. The energy distribution network is coupled to an energy transmission network at a point of common coupling and provides electrical power to the energy transmission network at the point of common coupling. The electrical power originates from the controllable network nodes. A central controller communicates with the local controllers and the energy transmission network. The central controller controls the energy distribution network with the aid of the communication with the local controllers and the energy transmission network such that at the point of common coupling, primary control power and short-circuit power are kept available for the energy transmission network.

  • Patent number: 9837896
    Abstract: An object of the present disclosure is to provide a DC-to-DC converter with a simple circuit configuration that continues the supply of direct current power to a load without providing a redundant power supply circuit even if a switching transistor operates abnormally in the active state. A protection circuit unit that converts an input voltage of a direct current input power supply to a different direct current voltage obtained by stepping down the input voltage, as in a direct current voltage conversion circuit unit including a first switching transistor, is connected between the direct current voltage conversion circuit unit and the direct current input power supply and, if the first switching transistor operates in an active state, direct current power of the direct current voltage converted by the protection circuit unit is supplied to a load causing the first switching transistor to maintain operating in the active state.
