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 multi-mode power supply is described for providing power to an impedance injection unit that is operable to inject reactive power into a power transmission line. The impedance injection unit is configured to operate safely in the presence of switching states of the impedance injection unit, and in the presence of disturbances such as surge currents in the power transmission line, by the multi-mode power supply clamping a potential overvoltage to a safe level. The power supply contains analog and digital circuits and can recover automatically from a surge current in the transmission line, or from a condition of zero line current. Power harvesting may be achieved via a line connected current transformer, via an internal current transformer, via a DC link capacitor, or from combinations of these.

Abstract: The power transmission tower mounted series injection transformer (TMIT) injects impedance and/or voltage on a transmission tower power line. A tension bearing tower uses vertical and horizontal insulators to support and stabilize the TMIT. The TMIT can be much heavier than a transformer device clamped to the high-voltage transmission line. The TMIT is connected in series with the tension bearing tower's jumper allowing it to use a multi-turn transformer. By operating at the line voltage potential, the TMIT does not require the large bushings and oil drums used by sub-station injection transformers.

Abstract: This patent discloses an active impedance-injection module for dynamic line balancing of a high-voltage (HV) transmission line. The impedance-injection module comprises a plurality of transformers each having a primary winding in series with a HV transmission line. Each transformer also has secondary windings, each connected to an individual electronic converter. The plurality of secondary windings are electrically isolated from the associated primary winding and extract power from the HV transmission line for operation of the converters and other circuits connected to the secondary windings. The active impedance-injection module is enabled to generate a controlled impedance, inductive or capacitive, to be impressed on the HV transmission line. A plurality of active impedance-injection modules spatially distributed on a HV transmission line are enabled to inject a controlled cumulative impedance on a HV transmission line while limiting the capacity of individual converters to that achievable with practical electronic components.

Abstract: A driver circuit for driving a solenoid, and related method, are described. A power supply charges one or more capacitors to a high voltage level sufficient to over-drive the solenoid. A switch is connected to the one or more capacitors and the solenoid. When the switch is on, the switch connects the one or more capacitors to the solenoid. When the switch is off, the switch disconnects the one or more capacitors from the solenoid. Control circuitry turns the switch on, and turns the switch off in response to sensing current through the solenoid reaches a defined maximum current.
