Abstract
A power adjustment apparatus includes a phase shifter including a stator having a stator winding and a rotor having a rotor winding, a winding terminal of one of the stator winding and the rotor winding being connected to a power-system bus, and a winding terminal of the other being connected to the power-system bus via an impedance load, a driver axially coupled to the rotor to drive the rotor, and a controller which gives the driver a command value to adjust the phase difference between the stator and the rotor to a desired value.
Claims11
A power adjustment apparatus comprising:
- a phase shifter including a stator having a stator winding and a rotor having a rotor winding, a winding terminal of one of said stator winding and said rotor winding being connected to a power-system bus, and a winding terminal of the other being connected to said power-system bus via an impedance load;
- a driver axially coupled to said rotor to drive said rotor;
- and
- a controller which outputs a command to said driver to adjust a phase difference between said stator and said rotor to a desired value.
A power adjustment apparatus comprising:
- a phase shifter including a stator having a stator winding and a rotor having a rotor winding, winding terminals of said stator winding and said rotor winding being directly connected to a power-system bus, the phase shifter having a leakage impedance of said stator and said rotor;
- a driver axially coupled to said rotor to drive said rotor;
- and
- a controller which outputs a command to said driver to adjust a phase difference between said stator and said rotor to a desired value to control power consumed by the leakage impedance.
