Senvion – MM77 (MM70 – MM100)
Brief introduction to Senvion MM77 wind turbines
Senvion launched their MM series in 2002 and the MM turbines have since become bestsellers in their portfolio – yielding optimal energy output while keeping noise emission low.
Like the rest of the turbines in the MM series the MM77 contains a double-fed asynchronous generator, a DC pitch system and a frequency converter.
Choose a certified retrofit solution for Senvion MM77 turbines
Nordic Wind Technology offers a certified software-only retrofit solution for Senvion MM77 turbines enabling owners/operator to gain full access and control of their turbines.
Our MM77 solution updates the software in the existing Bachmann Controller without tampering with the hardware in any way.
Upon completion of the update the pitch and converter systems will continue using the native parameters, and all safety features like overspeed guard, vibration protection etc. will function as they did before the update.
Since our retrofit solution for Senvion MM77 wind turbines is a software-only solution, the installation process is simple and efficient. Downtime is limited to 1-2 hours ensuring that related downtime costs are kept at a minimum.
