A compensation substation is a type of substation used only for compensation of reactive power of a power line or underground cable. It usually does not comprise transformers or switchgear except possibly switches for disconnecting the compensation components such as reactors or series capacitors.
How to map
Dedicated compensation substations are fairly easy to identify on aerial imagery. Important features:
- They are normally only present on long, high-voltage power lines (> 200 kV). Sometimes they will be adjacent to a "traditional" substation, but they can also be in the middle of lines.
- There is only a single voltage of line entering the substation
- The substation layout is normally quite simple, consisting of only a busbar and some compensation equipment.
