High Voltage DC breakers for transmission, ‘Small Wind’ solutions, switchgear for turbines highlight ABB’s presence in Chicago.
ABB, the wind industry’s leading power technology and grid interconnection solutions provider, today announced developments from the floor at the annual AWEA WINDPOWER 2013 conference and exhibition.
Technologies unveiled during AWEA WINDPOWER 2013, at the ABB booth (#3743), include:
- Small Wind market solutions – The US and Canada are leading the world in production of small wind turbines, defined by IEC 61400-2 as having a rotor swept area of less than 200 m2, giving a small wind turbine power of 100kW or less. ABB, with components in more than 40,000 wind turbines worldwide, is sharing its expertise in small wind designs and grid interconnections, including efficient and safe solutions for a complete electrical drivetrain.
- Ring Main Unit Switchgear. ABB will be demonstrating new ring main unit (RMU) medium-voltage switchgear designed specifically for wind turbines, enabling functions such as grounding, switching, disconnecting, cable connections and protection to be integrated with compact, cost-effective and maintenance-free functional units.
- ABB low voltage drives. ABB will be offering a full line of wind turbine converter solutions covering the complete wind market, including small, community and utility-scale wind farms. These drives’ features include HW and SW functions for fault ride-through and grid code compliance. ABB also is providing new grid integration, with PC simulation models for utility compliance studies. ABB offers test facilities to validate compliance.
- Forecasting the Wind. Ventyx, an ABB company, will be demonstrating its Ventyx Energy Portfolio Management (EPM) solutions, which focus on the siting, curtailment, and uncertainty of forecasting and valuation of wind generators.
“We’re pleased to again be a part of the AWEA WINDPOWER event as we establish ourselves as not only an experienced technology solutions supplier for the wind industry, but as a proven expert in connecting windpower to the transmission grid efficiently and reliably,” said Dennis McKinley, director of wind power solutions in North America for ABB.
High Voltage DC Breakers for Wind

ABB recently developed a powerful high-voltage direct current (HVDC) breaker that will significantly impact the use of wind-generated electricity. The HVDC breaker removes a 100-year-old technological barrier in the development of DC transmission grids.
DC can carry three times more power over long distances with up to 50 percent less power loss than alternating current. In the past, it was not widely used due to an inability to safely stop the current or identify errors across a power grid. The new HVDC technology facilitates the long distance transfer of off-shore wind energy into electricity networks in a safe, cost-efficient and power-saving manner.
The hybrid HVDC breaker development has been a flagship research project for ABB, which invests over $1 billion annually in R&D activities. The first uses are expected to be with integration of electric transmission from large-scale renewable power projects planned in Europe.
“Over the years, natural gas has presented the wind industry with pricing competition, but it is not an infinite source and experiences significant cost fluctuations,” said McKinley. “Wind energy will continue as a plentiful source, and ABB’s HVDC breaker represents a huge stride in harnessing the potential of wind energy as a viable power supply and improving the future grid.”
