|power = compensator|
|A static power device used to ensure power quality and electrical network resilience.|
|Used on these elements|
|Tools for this tag|
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
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)
There may be more complex systems, composed of several different component described below.
Such cases can be described with as many 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.
|power||compensator||Defines this node or 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||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 . 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.|
|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.|
