ABB, the leading power and automation technology group, has introduced a new 1400 frame size synchronous generator to expand its proven AMS platform. Covering the power range from 60 to 85 MVA at voltages from 3 to 15 kV, the new 4-pole generators enable higher unit powers and more economical genset designs. Advances in manufacturing technology…
GE completes acquisition of Alstom’s power and grid businesses
GE has officially completed the acquisition of Alstom’s power and grid businesses, following regulatory approval of the deal in over 20 countries and regions. It is GE’s largest-ever industrial acquisition, and spans the EU, the U.S., China, India, Japan, and Brazil. GE reached an agreement with Alstom in 2014 to purchase Alstom’s power and grid…
DNV GL awards component certification to ABB for offshore wind converter
DNV GL, the world’s largest resource of independent energy experts and certification body, has awarded ABB Switzerland with component certification for its latest generation main-frequency converter. The PCS6000 medium-voltage wind converter has been developed specifically for use in offshore wind turbines and is available for capacities up to 12-MW. The certificate was presented by Mike…
Innovator 2013: Francisco Oyague
Principal Engineering /Mechanical Design and Analysis /Boulder Wind Power It’s difficult to see how wind turbines can progress beyond conventional designs unless weight comes out of nacelles and reliability improves. A permanent-magnet generator that allows dispensing with a gearbox seems an alternative, but it comes with a high-weight handicap. Cisco Oyague, Principal Engineer, Mechanical Design…
Clever 3-MW generator heads to commercialization
A clever generator design that uses printed-circuit-board technology for lower weight and manufacturing simplicity has passed a 3.0 MW proof of concept and is headed to a nacelle for further testing. Developer Boulder Wind Power (BWP) has also expanded its electromagnetic design team to support the prototype generators with assembly and service tooling. “Having proven…
Cooling and controls let turbines generate more power
Grid Tie Inverter software uses proprietary algorithms to increase the range in which sustainable energy sources can deliver 60-Hz ac to the power grid. “We estimate an increase in efficiency of up to 25%,” says Energetic Drives’ CEO Ian Griffiths of the company’s algorithms. “For example, a traditional wind turbine generator has to be turning…
