6 FAQs about [How to measure the resistance of a wind turbine generator]

What are load measurements on wind turbines?

The chapter load measurements on wind turbines of the Aerodynamic Handbook gives an overview of different direct and indirect methods of measuring physical quantities on wind turbines. It focuses on a practical realization in an in situ environment and points out some dos and don’ts.

How does voltage affect power in a wind turbine?

You also found that as you change the amount of load in the circuit, the voltage changes only a small amount. If you have done Experiment 8 “ Exploring Wind Turbines ,” you found that when voltage and/or current increases in a circuit, the amount of power also increases.

Are in situ measurements mandatory for a wind turbine certification process?

Therefore, in situ measurements according to IEC 61400-13 ( 2015) and IEC 61400-12-1 ( 2017) are mandatory for a certification process of a wind turbine and recommended for validation of simulations and test benches (IEC 61400-22 2010, S. 72ff).

Why do wind turbines have a higher dynamic behavior than other machines?

In comparison to other modern machines, a wind turbine shows a higher dynamic behavior that is mainly affected by unsteady wind and working conditions, site factors such as wind farm effects, aerodynamics, grid back coupling, properties of different materials, natural frequencies of mechanical components, and many more.

Can a wind turbine sensor be bolted?

In most cases, a sensor on a wind turbine cannot be bolted, because of fatiguing the structure by drilling threads in it. Other possibilities for mounting is the use of adhesives or magnets, but one has to keep in mind that a sensor mounting can influence parts of the turbine.

How do wind turbine controllers work?

They detect environmental conditions, e.g., wind speed and yaw misalignment, and operational parameters like power production, current distribution, pitch angle, rotatory speed, oil temperatures, and many more to feed the controller with information to operate the turbine.
