Knorr-Bremse PowerTech delivers Reactive Current Converter for Wind Park Penamacor

The increased use of renewable energy is increasingly a challenge to grid operators to maintain grid stability. A result is that power stations are now often required to provide more adaptable grid-supporting functions in the form of so-called “grid codes” or feed-in regulations. In Portugal the grid code „Portaria 596” was published in 2010 and requires wind farm operators to retrofit wind turbines accordingly. Compliance can be achieved quickly and efficiently with Green Line 1000 reactive current converters. Integrated directly into Suzlon S88 turbines, the converters enable continuous grid operation during voltage drops and maintain compliance with fault ride through regulations. The entire system, comprised of the S88 from Suzlon and the Green Line 1000, has already received the relevant certification for grid compatibility from Germanischer Lloyd.

The Green Line 1000 reactive current converters have been deployed in over 200 systems from various manufacturers worldwide. Most recently, Knorr-Bremse PowerTech (formerly “PCS Power Converter Solutions”) supplied 66 Green Line 1000 units in 2013 to Suzlon Wind Energy South Africa (Pty) Ltd. for the East Cape Cookhouse Project in South Africa. The reactive current provided by the Green Line 1000 converters played an important role in South Africa’s move toward modern power supply specifications that match stringent requirements in other parts of the world such as Europe.

Knorr-Bremse PowerTech provides Green Line 1000 reactive current converters for upgrades in two performance classes. They are suitable for both smaller and larger wind turbines up to 2500 A and consist of a pulsed IGBT power converter with a voltage link. If the grid is operating under nominal conditions, the converters remain in stand-by mode. If the voltage on the grid drops, the converters are activated and supply the required reactive current for up to six seconds. For the wind farm Penamacor/Sabugal in Portugal the commissioning is planned in 2016.

Knorr-Bremse PowerTech is the merger of two leading power supply companies under the umbrella of the Knorr-Bremse Group. More than 500 employees at four sites on three continents work together to pioneer solutions for energy conversion. The Knorr-Bremse PowerTech portfolio includes converter products and electronic equipment for a broad spectrum of rail vehicles as well as energy production, storage, industrial applications and high end dynamic test rig applications.

The Knorr-Bremse Group is the world’s leading manufacturer of braking systems for rail and commercial vehicles. For more than 110 years now the company has pioneered the development, production, marketing and servicing of state-of-the-art braking systems. In the rail vehicle systems sector, the product portfolio also includes intelligent entrance systems, HVAC systems, power conversion systems, control components, and windscreen wiper systems, as well as platform screen doors, friction material, driver assistance systems and control technology. Knorr-Bremse also offers driving simulators and e-learning systems for optimum train crew training. In the commercial vehicle systems sector, the product range includes complete braking systems with driver assistance systems, as well as torsional vibration dampers, powertrain-related solutions and transmission control systems for enhanced energy efficiency and fuel economy.
