DOE picks Princeton Power Systems to develop converters for wind turbines

Princeton, N.J., October 19, 2010 – Princeton Power Systems announces a $1.8M grant award to accelerate development of its distributed generation transformer and E-QUAD Power Flow Control technologies for large wind turbine applications.

The award is through the Department of Energy’s Oak Ridge Office Xlerator program.

Combining a megawatt-scale converter topology with a high-frequency nanocrystalline-core transformer and silicon switching devices will result in a unique power converter that will control the generator, condition power, and transform it to transmission-level voltages in a single package. This will reduce the overall size and cost of the power conditioning system while increasing the conversion efficiency.

Furthermore, the multi-port E-QUAD Power Flow Control architecture can incorporate energy storage to provide grid support functions including frequency regulation, low-voltage ride-through, and giving wind farms access to full capacity credit. The technology will reduce the cost of balance of plant components like transformers and enable new generator technologies to get to market faster.

While originally developed for the early-stage tidal and wave power markets, the technology can have a more near-term impact on the more established and larger wind power markets. Many states in the U.S., including New Jersey, are undertaking investments in increasing on and offshore wind power generation over the next decade.

The DOE in August picked Princeton Power to develop a converter for hydropower applications. Read more here.
