Wind Turbine Safety


Wind turbines are designed with several safety features in place in order to help them continue to function in difficult weather conditions for many years. A domestic wind turbine is designed to last for 20 years, which translates to more than 120,000 hours of operation. When you compare that to a car’s engine, you see what a huge number of operating hours that really is. A car’s engine only operates for about 5,000 hours in its lifetime.

Here are some of the safety features that are built in to wind turbines to ensure that they continue to operate safely for many years.

1. Sensors

Every wind turbine contains a variety of wind sensors that help them to run effectively. One of the major sensors is the vibration sensor, which is basically a ball that sits on a ring. The ball has a chain that connects it to a switch. If the turbine begins to vibrate too much due to bad weather or other conditions, the ball will fall off of the ring, pulling the switch and turning the turbine off. This basic concept provides a significant measure of safety. There are other sensors, as well, such as thermometers that measure oil temperature and generator temperature.

2. Rotor Blades

There are safety regulations for the rotor blades of wind turbines which vary from one country to another. In Denmark, rotor blades must be tested statically and dynamically. Testing the rotor blades statically involves using weights in an attempt to bend the blades. Testing them dynamically means measuring the ability of the blade to tolerate fatigue.

3. Overspeed Protection

Overspeed protection is a safety feature that stops the spinning of the rotor blades on the wind turbine in the event of a malfunction.

4. Aerodynamic Braking System: Tip Brakes

Most wind turbines use an aerodynamic braking system as their primary braking system. This means that the rotor blades are turned 90 degrees. They are spring operated so that they will work even if there is a power failure. Aerodynamic braking systems will stop the wind turbine within a couple of rotations, and have a proven history of safety. They are a gentle method used to stop the turbine without exerting unnecessary wear and tear on the turbine.

5. Mechanical Braking System

Many turbines use a mechanical braking system as a backup to the aerodynamic braking system. It acts like a parking brake and keeps the turbine in a stopped position.
