4. Electromechanical structures & electrical connection with grid
Electromechanical structures: powerhouse, hydraulic turbines ( types and configuration, specific speed and similitude, preliminary design, selection criteria, efficiency), speed increasers (types, design, maintenance), generators (configurations, synchronous- asynchronous –dc generators, exciters, voltage regulation and synchronization, special specifications), turbine control, switchgear equipment, automatic control (governor – automatic voltage regulator – case of autonomous operation), ancillary electrical equipment (plant service transformer, DC control power supply, headwater and tailwater recorders, outdoor substation)
Connection of hydro-power plant with grid through transmission / distribution lines: steady state and transient state current analysis for different operation modes, faults, power quality issues, power stability
