Wind measurement system in wind power plants

How to measure wind data for wind power plants?

To measure wind data for wind power plants, there are many good wind measurement masts with equipment available. These include cup anemometers for measuring wind speed and wind vanes for measuring wind direction. Additionally, temperature and air pressure should be recorded.

What is the capacity factor of a wind power plant?

The capacity factor, which is the most important parameter during the definition of wind energy potential of one region, is identified as the proportion of energy generated by a wind power plant to the energy that has to be generated at nominal power .

How is the net power of a wind turbine measured?

Measuring the net power of a wind turbine may require measuring power in more than one location to include the turbine’s consumption as well as output. Power can be measured using a power transducer or current and voltage transducers. Measuring net power in this way is important for understanding the efficiency of the wind turbine.

How accurate is wind speed measurement?

Users of wind speed measurement data for the assessment of available wind energy often request a rather high accuracy in the order of 1%, because wind energy depends on the third power of the wind speed (51.1). A 1%-error in wind speed thus means up to 3% error in wind energy.

How do wind turbines measure wind speed?

Wind turbines measure wind speed using a cup anemometer installed on the nacelle. The wind speed is read by the wind turbine controller to assist in determining the operation. The wind speed may determine if the wind turbine should start idling or shut down at cut-out wind speeds.

What are the different types of wind turbine monitoring systems?

Wind turbine monitoring systems can be broken into two major categories: those that measure the flow field and surrounding atmosphere around and within a wind plant, and those that measure the turbine response within the wind plant.
