Computer Controlled Hydroelectric Power Plant with Francis Turbine

The Computer Controlled Hydroelectric Power Plant with Francis Turbine with the aim of reproducing, at laboratory scale, the real behavior of an industrial hydroelectric power plant. It allows the user to study, in an integrated way, the process of converting hydraulic energy into electrical energy (requires the recommended accessory HPPF-CR).
