Hydropower Plant Alster · Karlstad
A full modernization of the control, excitation and hydraulic systems for reliable, yield-optimized operation.
Complete renewal of the automation system
At 7 m head and 5,000 l/s flow, Hydropower Plant Alster in Karlstad delivers 350 kW. The machinery consists of a 130 kW Francis turbine and a double-regulated 220 kW Kaplan turbine, both with synchronous generators.
The complete control system was renewed. The scope also included a new excitation unit for both synchronous generators, remote monitoring and automatic level control, providing transparent operation and central oversight.
