S&C Ships Second PureWave DSTATCOM^® to UK for Wind Farm

S&C Electric Company recently shipped a PureWave DSTATCOM® Distributed Static Compensator to the UK for installation at Renewable Energy Systems’ Dun Law Extension Wind Farm, located near Edinburgh, Scotland. The ±5 MVAR inverter-based system is in the process of being placed into service. The Dun Law Extension Wind Farm features 35 turbines with an output of 30 MW, complementing the 17 MW produced at the original Dun Law Wind Farm.

The PureWave DSTATCOM includes step-up transformers and switchgear as well as switched capacitor and reactor banks. The system meets UK compliance testing requirements—a prerequisite for wind farms to meet the rigorous Grid Code interconnection standards. These standards include complex interconnection specifications which call for continuous voltage regulation or reactive power control with very rapid response.

Andrew Jones, Managing Director of S&C Europe, noted “S&C has demonstrated their familiarity with utility system practices and expertise in designing systems to help wind farm developers meet Grid Code requirements. Customers can be confident that in purchasing a PureWave DSTATCOM, they are not just buying a compensation system, but a solution backed by S&C that will be fully Grid Code compliant.”

Brian Murdoch, RES Project Manager, noted “The Dun Law Extension Project is the first DSTATCOM that RES has installed. RES has been impressed with the professionalism and experience demonstrated by S&C throughout the design, manufacture and installation of the equipment. S&C has also carried out electrical study and modeling work on behalf of RES to a high degree of detail and have demonstrated in-depth knowledge of UK grid requirements and, indeed, the operational properties of the wind turbine electrical profile. RES are confident Grid Code compliance testing, due to be carried out in August 2009, will be successful and the DSTATCOM system will perform its required function.”
