Wind turbine overspeed control system

What is an over-speed wind turbine FM control strategy?

Then an over-speed wind turbine FM control strategy considering the optimal operating point is proposed. The control strategy solves the optimal operating point under different wind speeds through the frequency regulation energy model, and makes full use of the reserve capacity of the WTG to participate in the frequency regulation.

Can light detection and ranging prevent rotor overspeed?

Light detection and ranging (LIDAR) systems can be used to provide wind inflow information to a wind turbine controller before the wind reaches the turbine. Both fatigue and extreme load reduction are possible as a result; in this research, we propose a LIDAR-based controller designed to prevent emergency shutdowns caused by rotor overspeed.

What causes wind turbine overspeed peaks?

Turbulent and gusty wind conditions can cause generator overspeed peaks to exceed a threshold that then lead to wind turbine shutdowns, which then decrease the energy production of the wind turbines. We derive so-called “gust measures” that predict when generator overspeed peaks may occur.

How does a rotor controller reduce the cost of wind energy?

The controller in Region 3 reduces the cost of wind energy through the reduction of loads while maintaining the rated generated power. An example of an event that causes large loads on the turbine structure is an emergency stop. An emergency stop can occur under several different conditions, one of which is rotor overspeed.
