Abstract
Grid codes are technical requirements and standards that govern electrical grids, ensuring reliability and safety. These codes have evolved to accommodate changes in technology, policy, and environmental concerns. With increasing penetration of renewable energy sources such as wind power, grid codes have become more demanding. Compliance with grid codes is crucial for wind turbine manufacturers; power plants must withstand voltage transients and operate within specified limits. Grid stability is an additional challenge where available connection points do not meet requirements. To address these challenges, Siemens Gamesa is conducting a technology development project called FASTAP, meaning “fast tap” change, funded by the European Union’s Horizon 2020 program under grant agreement No 971145. This project focuses on developing Dry-Type Transformers (DTT) and Oil-Immersed Transformers (OIT) with Electronic Tap Changers (ETC) to enhance Wind Turbine Generator (WTG) capabilities and support grid compliance. Potential benefits are cost savings and improved performance, especially for weak grids.
