Design and optimization of wind energy systems with direct-driven permanent magnet synchronous machines
Vector control of electrical drives (motors and generators) for special applications (high-speed, very large dynamic range, etc)
Monitoring of the ageing state of power transformers by means of behavioural models using intrusive and non-intrusive (external) measurements.
Simultaneous measurements of temperature and vibrations in power transformers with fiber optic sensors.

3,5 kW bench test facility including a torque- controlled d.c. motor simulating the wind turbine and a low-speed permanent magnet synchronous generator coupled to the grid by a power converter controlled by two DSP's.
A similar 15 kW bench test with a.c. motor. The machine under test is coupled to a 75 kVA synchronous generator acting as a cuasi-infinite bus. This facility allows to analyze the impact of wind generators upon the grid (harmonics, flicker, reactive control, etc).
25 kVA, 15 kV power transformer test facility with sensors (fiber optics, accelerometers, etc) and dynamic signal analyzer.
