kk-electronic and B&R in retrofit cooperation

Danish Wind power controller supplier kk-electronic teams up with B&R to breathe new life into aging turbines.
By equipping existing turbines with B&R X20 control electronics and advanced software packages from kk-electronic, this alternative to repowering promises to extend their productive life, significantly reduce downtime and make them more profitable for longer.

Costly downtime demands action

When a wind turbine fails post-warranty, research has shown that 42% of problems can be traced to component failure, while another 21% can be attributed to the failure of control systems that were unable to endure a harsh environment for such extended periods of time.
This downtime is further compounded by the increasing difficulty of obtaining replacement components for outdated systems. With aging turbines producing below capacity and becoming unjustifiably costly to maintain, it quickly becomes clear that something must be done.

This is the challenge that kk-electronic and B&R set out to solve. As an alternative to the costly repowering approach, which involves replacing entire turbines, the two specialists instead explored the possibility of retrofitting the control system.

“With this step, we’re focused on the requirements of our customers and the industry,” says Tonni Birk Sørens­en, Senior Vice President of kk-electronic.
