Abstract
A system for controlling voltage comprising a transformer having a terminal, a plurality of windings and a plurality of winding taps. A voltage monitor coupled to the terminal of the transformer and configured to generate voltage data representing a voltage appearing at the terminal of the transformer. A non-bridging tap changer controller coupled to the voltage monitor and configured to generate tap changer control data for changing a configuration of a tap changer in response to the voltage data. A tap changer motor coupled to the non-bridging tap changer controller and configured to move the tap changer in response to the tap changer control data.
Claims20
A system for controlling voltage comprising:
- a transformer having a terminal, a plurality of windings and a plurality of winding taps;
- a non-bridging tap changer controller configured to generate tap changer control data for changing a configuration of a tap changer in response to voltage data to prevent a tap setting that bridges two windings;
- and
- a tap changer motor coupled to the non-bridging tap changer controller and configured to move the tap changer in response to the tap changer control data.
A method for controlling voltage, comprising:
- changing a tap setting of a transformer with a tap changer device if a voltage signal is outside of a predetermined voltage range;
- determining with a processor or circuitry whether a new tap position is a bridging tap position or a non-bridging tap position;
- and
- changing the new tap position to an adjacent tap position with the tap changer device if the new tap position is a bridging tap position.
A system for controlling voltage comprising:
- a transformer having terminals, a plurality of windings and a plurality of winding taps;
- a non-bridging tap changer controller configured to generate tap changer control data for changing a configuration of a tap changer in response to voltage data to prevent a tap setting that bridges two windings as a function of a voltage appearing across the terminals of the transformer and without a differential voltage between two transformers;
- and
- a tap changer motor coupled to the non-bridging tap changer controller and configured to move the tap changer in response to the tap changer control data.
