How do I synchronize a gen-set to the mains? What AVRs do you support? What Speed Governonrs do you support?
The ComAp product portfolio includes controllers that can control voltage and speed and with those products our controllers are able to synchronise to the mains.
Synchronizing a gen-set to mains (or multiple gensets to each other) is a procedure which requires the following conditions to be met before you connect the two electrical systems together:
- Matching voltage in all phases of both systems.
- Matching frequency of both systems.
- 0° phase angle between both systems. (Or as close to 0° as possible.)
- Matching sense of rotation of both systems.
The last condition is predetermined by wiring and needs to be checked prior to commissioning, the rest can be controlled by a ComAp device. In order to do so you need to interface the generator AVR (Automatic Voltage Regulator) and the engine Speed Governor. ComAp controllers designed for paralleling operations typically have outputs designed for this connection. Thanks to this we are able to control the generator voltage and the engine speed (and subsequently phase angle).
The procedure of configuring the speed and voltage regulation is described in the relevant documentation.
The same document also contains the list of supported AVRs and Speed Governors including the wiring and configuration setpoints.
