TURBINE RETROFIT
SENVION MM77
BENEFITS OF RETROFIT ON Senvion MM77
Retrofitting older wind turbines like the Senvion MM77 instead of investing in new ones is a green and profitable solution.
The innovative software update from Nordic Wind Technology provides turbine owners/operators with a host of benefits, including a significant increase in AEP, 100% independence from Senvion, freedom to choose your service provider, and much more:
- Upgraded data access and improved service tools to lower O&M costs
- Access to spare part supply chain, spare parts available directly from the manufacturers
- Pitch module (MOOG and L & B)
- Converter (WOODWARD, ABB)
- Grid module (WOODWARD)
- Optimized availability and energy production with control of mechanical loads
- Flexibility to add own extensions, including sensors or CMS system
- Enhanced remote turbine monitoring and control
- Power curtailment and reactive power control, enabling previously unattainable incentives by complying with modern grid codes
- Fast installation time, only 1-2 hours downtime for installation
GENERAL INFORMATION
TURBINE MODEL
Senvion MM77
YEAR OF MANUFACTURE
Launched in 2002
FURTHER INFORMATION
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.
BACHMANN SOLUTION
All of the turbines in Senvion’s MM series contain a Bachmann controller. The Senvion MM77 retrofit solution from Nordic Wind Technology updates the Bachmann controller with new software.
The installation process is uncomplicated and fast. We simply replace the Compact Flash card in the Bachmann Controller, and the turbine is up and running again within an hour or two.
The software update does not interfere with the existing hardware, and the safety features in the turbine, e.g., overspeed guard, vibration protection, etc., remain as they were before the update. The same applies to the pitch and converter systems, which will continue using the native parameter configurations.
