A voltage regulator, step voltage regulator (OSM) or a power booster (421-01-12) is a power compensator which operates with the help of one or more transformers to alter the voltage of a given alternative current circuit.
Those regulators act as a particular kind of compensators and aren't compatible with power=transformer in OSM.
Most of the time, they may be used in following situations:
- Long reach power distribution networks, to ensure subscribers are provided with appropriate voltage
- Offshore power links carrying power from wind production facilities to continental transmission network
They can be found in transmission substations or along long reach distribution power lines. Many processes actually exists to alter voltage, using electro-mechanical machines, simple feed-forward or more complex electronics, depending on the voltage to regulate or power to forward.
Let's note this value was added after the Proposed_features/Substation_refinement approval and should keep the in use status until further review.
Possible confusion with phase angle/quadrature boosters
Some transmission boosters may be found with an architecture looking like phase_angle_regulator transformers. However, such power boosters and phase_angle_regulator transformers clearly differs:
- The booster's shunt transformer is usual star-star and there is no phases swapping between shunt and series secondaries.
- The phase_angle_regulator's shunt transformer is primary delta and secondary taped series. See Wikipedia. Phases are swapped in the connection between shunt and series units' secondaries.
Visually, a booster transformer is inserted in series in a power line while the phase_angle_regulator transformer is in parallel with the power line it regulates.
They should not be confused as they achieve a completely different function.
How to map
First of all, please refer to general guidelines on power=compensator.
Boosters transformers are usually a single machine even for multiphase systems and they should be mapped a single node.
As we found them on alternative current systems only, amount of different phases is documented with phases=* instead of cables=*.
Examples
We definetly need some high voltage regulators installed on transmission lines here. Feel free to add one of them.

Japan |
|
A step voltage regulator intended to boost voltage on Japan distribution network. Installed outdoor and supported by poles, it is inserted in series in a 6 kV power line. Visual signage gave us the 3 MVA rating. |

Canada |
|
A step voltage regulator set intended to boost voltage on Canadian distribution network.
Installed outdoor and supported by poles, it is inserted in series in a 20 kV power line. Picture author stated itself each phases is rated at 576 kVA, which means an overall rating of 1.7 MVA. As it's a set of three devices, we can still map them as a single node, puts tags for a single device and add devices=3. |
