Development, Validation and Certification of Ingeteam’s Power Converter in Suzlon’s S11x Wind Turbine
During the last 20 years, wind power’s share in electricity generation has substantially grown, making the power quality and stability of wind systems increasingly important. Consequently, the grid codes (which establish the requirements that all generation systems must fulfil in order to be allowed to connect to the grid) have been updated in order to guarantee the stability of the grid. Until the recent past, wind turbines were allowed to disconnect from the grid when transient changes in grid voltage might jeopardise the integrity of their elements, especially the power converter. However, nowadays, this is no longer allowed. Moreover, the turbines must also support the grid with active and reactive current during these transient conditions.

In particular in India, wind power has experienced a huge growth within the last few years. The country’s installed capacity is currently greater than 28GW and an additional 3,612MW were installed in 2016 alone, according to the Ministry of New and Renewable Energy (MNRE) of India. Because of its rapid growth, the Indian electricity system faces the challenges described above in terms of grid stability.
