Alstom wins Frost & Sullivan technology award

Sponsored by

Alstom Grid has been honored with Frost & Sullivan's 2012 European Award for Technology Innovation, for achievement in the voltage source converter (VSC) high voltage direct current (HVDC) transmission technology market.

Alstom Grid is commended for its newest generation HVDC product that helps to tackle the cost, space and efficiency issues generally associated with classic Line Commutated Converter HVDC solutions, and opens the door for many additional applications.

Alstom's HVDC MaxSine (1st and 2nd generation) is a family of voltage source converter (VSC) technologies that improves the functionality of HVDC transmission.

HVDC transmission is one of the most effective technologies for long distance transmission. The 2nd generation HVDC MaxSine technology overcomes the traditional challenges associated with HVDC by leveraging its inherent hybrid topology that can handle multiple interconnections. This makes the technology readily available to address the demands of rapidly growing application areas like offshore wind farms and also reliably support the traditional large grids.

This feature brings additional functionalities in applications such as multi-terminal DC grids, where the HVDC MaxSine not only isolates the DC fault but also offers support to the AC grid if a major fault occurs. This feature is especially important in the formation of future DC grids. Apart from higher reliability of HVDC, which also results in lower distortions and losses, the HVDC MaxSine also offers other advantages that impact customer value.

For instance, HVDC MaxSine converters are scalable and modular, allowing them to be adapted to any space requirement.

The converter modules can be stacked vertically or horizontally, depending on site limitations and is ideal for offshore wind power plants where floor space is restricted.

VSC is a future technology that will connect most of the fluctuating, renewable energy sources such as on- and offshore wind power. To leverage the development of the HVDC MaxSine technology, Alstom Grid has invested in a 24 MW VSC demonstrator unit in Stafford, U.K. to enable the long-term testing and development for the VSC converter technology.

Frost & Sullivan Best Practices awards recognize companies in a variety of regional and global markets for demonstrating outstanding achievement and superior performance in areas such as leadership, technological innovation, customer service, and strategic product development. Industry analysts compare market participants and measure performance through in-depth interviews, analysis, and extensive secondary research to identify best practices in the industry.
