EEI has undertaken the development of solutions for the parallel connection of wind turbines from 60 to 300 kW with an asynchronous and synchronous permanent magnet generator. This configuration allows to eliminate the gearbox and to supply energy even when the frequency is variable.
The control logic was developed to actively manage abnormal operating conditions (lack of network; strong winds) regardless of the security system adopted (hinge upwards, pitch control, etc.).
THE MAIN CHARACTERISTICS OF EEI CONVERTERS ARE:
Efficiency: IGBT active front end,
Reliability: only thin film DC link capacitors and modular design to facilitate maintenance operations
Security: self-protection functions
Quality in energy production: low THD (I), adjustable power factor
Flexibility: cutting-edge solution, developed and designed according to customer needs
