On behalf of VOITH Hydro, I have commissioned a new brushless excitation system in Kilforsen. The PLC was a Siemens Simatic S7, so after 25 years in business, I finally worked with a Siemens equipment.
Kilforsen is a hydro power station in Fjällsjöälven in north of Sweden owned by Vattenfall. It is one of the major hydro power stations in Sweden, with 3 units. Each unit is rated 116 MVA.
