Wind

The USA wind market is entering the second generation of technology and growth. There are increased demands for greater system reliability over the desired twenty year life of the turbines and farms. Although most of the reliability issues have been with the mechanical subsystems of the wind turbines, electrical reliability issues with power converters, power protection and power control components have begun to appear. 
Most of these issues are due to using IEC rated components rather than UL/ANSI rated components, which are designed to the three to six times current over-rush conditions commonly found in the collection system of USA wind farms. Although regulatory agencies have not yet established their presence in the USA wind market, UL, NEC and OSHA are actively reviewing their position on entering the market, even though American Wind Energy Association is lobbying against such regulation. 
In any event, the best approach is to develop power conversion, distribution and control equipment that is readily able to certified IEC, UL or ANSI and even CCC & GB for the China Wind Market, to stay ahead of the dynamics of the wind turbine and farm markets.
AETI, along with its operations M&I Electric, are one of the few wind turbine and farm equipment providers able to provide custom power conversion, distribution and control equipment rated to any to the world’s globally recognized certifications for the following wind market segments.
  1. Small Wind Turbine OEMs from 100 kW to 750 kW
  2. Big Wind Turbine OEMS from 750 kW and above to 3 MW
  3. Wind Farms that typically create 34.5 kV collection systems and substations
AETI works with the wind markets in the following ways:
  1. Working directly with wind turbine OEM engineers to develop and implement custom and integrated power conversion, protection and control equipment able to be delivered “through the door”.
  2. Working directly with wind farm developers and system integrators to develop and implement custom bundled power distribution, power collection, substations, electrical yards and grid interconnection.
  3. Working directly within engineering procurement & construction firms to provide electrical oriented site audits, construction, installation, start-up and commissioning during the build of the farm.
  4. Working directly with utilities, PPAs and electrical coops to provide farm electrical maintenance, testing, auditing, repair and refurbishment services.
