Systèmes Eoliens

This 4- to 5-session course introduces the main concepts involved in converting wind energy into electricity, from the main components of wind turbines to the architectures of modern onshore and offshore wind turbines. Course content includes:History, background and markets of wind-generated electricity. Main market players; factors driving and holding back the sector's expansion. Elements of cost and development of a wind farm.

Characterization of the wind resource (wind), altitude and wake effects, theoretical elements (Betz limit) on wind productivity and the energy efficiency of wind turbines; from mechanical control by blade adjustment to operating zones from start-up to safe shutdown.

Construction of electric wind turbines: nacelles with and without speed multipliers;

design elements for wind turbine chains according to size and technology;

Transient analysis and stable setting of the operating point in the torque-speed plane;

Main power conversion architectures for asynchronous and synchronous power trains, with and without gearboxes, and with and without power electronics; Elements of active and reactive power control in these power trains.

Basic knowledge of energy physics (energy/power concepts), basic knowledge of electricity and electromechanical conversion (basic knowledge of electrical generation).
