Abstract
A device for supplying energy to a long stator winding having multiple winding sections. The device includes an energy source, a supply line connected to the energy source, section switches that are connected to the supply line and that each have a connection for connecting the switch to one winding section each. The device is configured to enable reactive (idle) power compensation independently of the closed-loop control of the energy source. The device for the reactive power compensation is configured to adjust the impedance of the device.
Claims5
An apparatus for supplying power to a long stator winding formed with a plurality of winding sections, the apparatus comprising:
- an energy source and a supply line connected to said energy source;
- a plurality of section switches connected to said supply line and each having a connection to a respective one of the winding sections of the stator winding;
- and
- reactive power compensation means connected to and configured to adjust an impedance of the apparatus, said reactive power compensation means including a control unit configured to open or close at least some of said section switches, said control unit being connected to measurement sensors generating measurement signals, and said control unit including internal control logic configured to open or close said section switches that are connected to said control unit, as a function of adjustment parameters and based on the measurement signals.
