Suzlon Group says it has completed type testing and certification of its S111 turbine for 50 Hz and 60 Hz variants.
According to Suzlon, this certification acknowledges conformity with standards and regulations for the design, testing and manufacturing of the S111, which belongs to the 2.1 MW class.
This model features a rotor diameter of 111.8 meters and a swept area of more than 9,500 square meters, says Suzlon, which adds that the S111 delivered approximately 102% of its design power curve – translating to higher-than-projected power generation and improved returns for customers.
The testing was carried out by an independent, third-party agency; the certification was awarded by TÜV NORD.
“This is the third consecutive blade program where the certified performance has exceeded our design goals,” says Duncan Koerbel, chief technology officer of Suzlon Energy. “This is a tribute to our multinational [research and development] teams located in Germany, the Netherlands, Denmark, USA and India.
“Our aerodynamics and system design capabilities continue to improve – leading to better annual energy production of wind power plants. The 2.1 MW platform currently has more than 3,500 turbines installed in 17 countries, with over 92,253,180 operating hours. The new S111 blade has been designed to optimally harness available wind – delivering nearly 20 percent higher energy as compared to the S97, thereby ensuring higher [return on investment] to customers,” Koerbel continues.
