Commissioning of control system in Dönje, hydro power station.

On behalf of VOITH Hydro, I have commissioned the updated unit controller (HPC Compact, based on AdvantController 110), as well as the HMI (ABB 800xA).

Unfortunately, during open circuit tests, when generator voltage was brought up to nominal level, there was a stator earth fault. Heavy smoke was detected and the underground power station had to be evacuated.

Commissioning will continue when the generator stator has been repaired.

Finally I will do performance tests on all units and provide test records to Svenska Kraftnät.
