Control system for horizontal Francis turbine with 132kW output

In 2004 a new hydro-electric power station was put into operation in the city of Fujiyoshida (central Japan). All industrial devices (Francis turbine, induction generator, water intake device and electrical installation with Tecomat PLCs) were implemented by the Czech company CKD TURBO TECHNICS s.r.o., and the joint-stock company Mavel a.s. incorporated.

The hydro-electric power station is composed of the 132kW output horizontal Francis turbine connected with induction generator via dry-disc joint, a control hydraulic unit of the Francis turbine, water valves controlled from the control room and intake devices (water-gate, trashracks and telescopic trashrack winnower).

All operations (failure automatics, drives, supervisory and control units) are handled by one PLC Tecomat TC 600. User software implemented by CKD TURBO TECHNICS s.r.o. company controls operation of the machine unit, water inlet and allows unmanned operation of the hydro-electric power station.

The central (SCADA-based) control system of the hydro-electric power station, including the entire visualization, is provided by the Reliance system. The Reliance system permits a remote view and visual control of the hydro-electric power station via the Internet.
