Siemens Gamesa Renewable Energy (SGRE) has announced the introduction of a new onshore wind turbine platform, the Siemens Gamesa 5.X platform, which encompasses two models, the SG 5.8-155 and the SG 5.8-170. The platform introduces the largest unit capacity in the SGRE onshore portfolio, 5.8 MW rated capacity, and the largest diameters, 155 and 170 m, resulting in maximum performance in high-, medium-, and low-wind conditions. The 170 m rotor is the largest in the onshore segment.
The SG 5.8-155 has a 14 per cent larger swept area than the SG 4.5-145, and an increase of over 20 per cent Annual Energy Production at 8 m/s. The SG 5.8-170 gives an increase of over 37 per cent in swept area and more than 32 per cent in AEP at 7 m/s when compared with the SG 4.5-145.
These wind turbines feature a doubly-fed generator, partial converter, and a compact drive train designed with a three-stage gearbox. The new turbines integrate advanced control technologies and strategies that optimise their efficiency on the basis of site conditions, offering flexible power ratings depending on noise requirements, ambient temperature, and electrical performance.
The first prototype installation of the SG 5.8-155 is planned for mid-2020, with production scheduled to commence in Q4 2020. The first prototype for the SG 5.8-170 is planned for Q3 2020, and production will start in Q1 2021.
