Control system to avoid shadow problems

Wind turbines can cause shadows, which can be disturbing, for example at nearby buildings. When the blades rotate, a stroboscopic effect can arise inside windows affected by this. Large wind turbines, which have sophisticated control systems, can have opportunities to stop automatically at the times when this can be a problem. Small wind turbines are usually simpler built and has until now lacked such opportunities.

TEROC has recently developed a control system for this purpose, used by InnoVentum for a small wind turbine installed at the Blekinge Institute of Technology. Stop conditions can be easily configured and functionality can be monitored remotely.
