Another new wind power generator series from ABB

2010-09-01 - In addition to the generator launched earlier this year for the economical doubly-fed system ABB is now introducing a new family of permanent magnet generators for 1.5 – 3.6 MW wind turbines. The new series offers an easy upgrade route to the next level of total power control and advanced grid compliance of the full converter concept.

Helsinki, FIN, September 1, 2010 - Leading power and automation technology group ABB is introducing a new series of high speed permanent magnet generators (HS PMG) for full converter (FC) turbines. The new series will be launched at Husum WindEnergy 2010 featuring a design based on ABB’s proven technology and extensive experience in low, medium and high speed PM generators since the 1990s.

PM generators are synchronous machines with rotor windings replaced by permanent magnets. This eliminates excitation losses in the rotor, which typically represent 20 - 30 percent of total generator losses. The main benefits are robust construction, high power output with small size, and high efficiency at all speeds. PM generators offer the highest annual production of energy combined with the lowest lifetime cost.

The new high speed generator family covers the power range 1.5 - 3.6 MW. The generators are in principle mechanically interchangeable with those used in present mainstream doubly-fed turbines, which make the task of upgrading to FC system easy. Their modular and adaptable turbine interface connections enable to fit it in most turbine designs of today. Features of the new generator also include a patented rotor design withstanding overspeeds up to 3000 rpm. ABB’s optimized product platform and large-scale manufacturing experience using powerful magnets enable it to offer cost-efficient generators with fast delivery times.

ABB has experience in manufacturing all types of demanding motor and generator designs since 1889, and a strong reputation as a reliable supplier to the wind power sector. It is known for its proven generator - converter packages, as well as delivering a wide range of electrical components for wind power systems. Leading turbine manufacturers rely on ABB technology. Over the last 30 years ABB has supplied around 30 000 generators for wind turbines, totalling some 30 000 MW.
