Grid connections technologies
Thanks to their design and technology, Gamesa wind turbines meet the most demanding requirements of connection to the electricity grid.
DFIM technology (Doubly Fed Induction Machine) in combination with the Gamesa WindNet® system (new SCADA developed by GAMESA), allows the regulation of active and reactive power via the injection of rotor currents of variable amplitude, frequency and phase
For voltage ride-through, Gamesa has developed a trustworthy and robust solution based on an Active Crowbar and an oversized converter. The Active Crowbar consists of an electronic power device which allows the continuity of connection of the machine during a voltage fault and prevents both over-voltages in the DC bus and over-currents which could damage the other electronic power elements.
For the dynamique regulation of reactive power, Gamesa WindNet® calculates the power factor dynamically and corrects it continually in accordance with the reference values of the System Operator. Gamesa WindNet® acts both on the capacity for regulating the reactive power of the machines and, if it existed, on the equipment in the substation (capacitor banks and FACTS systems).
Gamesa WindNet® integrates also active power and frequency regulation tools
