Various components are used for controlling reactive power and voltage quality in a power grid. Here are some suggested tags for different types of compensators.

How to map

Basically, a compensator whatever its type is mapped as a Node with power=compensator on.
You can add extra details about its actual location with location=* and its operator=*.

Such device may be seen mostly in power substations but along power lines too.
We can see them in factories or large industrial sites, but often in a local substation dedicated to industrial power feeding (substation=industrial)

Advanced mapping

There may be more complex systems, composed of several different component described below.
Such cases can be described with as many Node as components involved in the system, depending of what you see in a survey or aerial imagery.
All components may be linked with power=line + line=bay ways.

Tagging

Key Value Comment Recommendation
power compensator Defines this node Node or area Area as a compensation component mandatory
compensator <compensator type> See below for possible values. This tag should be specified when the compensator type is known recommended
voltage <voltage> The voltage at which the compensator is operated recommended
rating <power> Mvar/kvar The power rating of the compensator. The unit should be Mvar (megavolt-ampere-reactive) or kvar (kilovolt-ampere-reactive) recommended

Compensator values

Key Value Comment
compensator shunt_reactor A shunt reactor absorbs excess reactive power. It looks like a transformer but has no secondary terminals.
shunt_capacitor A shunt capacitor bank generates reactive power
static_var A static var compensator (SVC) comprises a thyristor controlled reactor, normally a thyristor switched capacitor and often fixed or switched reactors and capacitor banks.
statcom A static synchronous compensator (STATCOM) is a transistor based compensator (its design is similar to a VSC converter, see above).
synchronous_condenser A synchronous condenser is a large rotating synchronous machine (similar to a generator) for generating or absorbing reactive power.
filter A harmonic filter is used to eliminate harmonic currents generated by an HVDC converter. These can be quite large and may appropriately be mapped as Area. Other types of filters for removing undesired frequency components may also occur.
series_reactor A series reactor is used for controlling load sharing between parallel power lines or for limiting short circuit currents. The smoothing reactor of an HVDC converter is also a series reactor.
series_capacitor A series capacitor is sometimes inserted in a long power line to increase the transmission capacity.

voltage_regulator

A voltage regulator keeps voltage flowing onto a power line constant throughout its loads. These are usually used on power plants or placed in the middle of a long distribution line.
