Energie Wasser Bern Felsenau hydroelectric power plant is situated on the Aare River in Bern, Switzerland. The electricity capacity of the Felsenau power plant is 11.3 MW. The annual production amounts to about 70,000 MWh. The plant was completely renewed 1986-89 to an automated bulb-turbine plant. Since then several electronic components for installed control system have become unavailable. The power plant was forced to replace the control, protection and some other systems. It proved to be most cost effective to modernize the entire control system at the power plant and the Engehalde dam. Fortunately, this also became an opportunity to raise the automation level of the plant. In its new configuration the raised automation level includes, in addition to conventional functions, replay function for fault clearing, simulator for operator and maintenance crew training, advanced river/dam control and SIL 3 machine mechanical protection system. The new control system, while reaching a high level of integration, is still maintaining the similarity to previous operator interface, making the transfer from earlier to new system as smooth as possible.
