Autopilot Windfarm Control

Autopilot The ADMS provides an autopilot for programmed supervisory shutdown that is initiated by pre-specified site conditions. The autopilot feature can be used to shut down selected turbines in high or low winds, or winds from particular directions. This feature can be used to control site noise and/or reduce wear and tear on the turbines.

For example: When turbines on a windfarm are closely spaced, “column winds” (strong winds moving directly parallel to a row of turbines) cause turbulent tip wakes to flow through the adjacent turbine rotor. This can cause damaging vibrations in the wind turbine that result in premature failure of expensive components. The autopilot will shut down pre-selected turbines, under pre-selected conditions, and then restart them when acceptable conditions have returned, thereby minimizing stress on the turbines and reducing windfarm maintenance.

The autopilot feature can also be utilized to reduce noise. Under certain low-wind conditions, a specific turbine (or array) might disturb a nearby neighbor if its noise is considered unacceptably louder than ambient. In this circumstance, autopilot can shut down pre-selected turbines without sacrificing overall power production, and then restart them when the wind increases to a reasonable, and profitable, level.
