Wind power low voltage generation voltage range

Why is low voltage ride through important in wind energy conversion system?

The high penetration of grid connected wind energy has emerged as a recent trend in many countries. On the other hand, the problem of power generation loss due to the grid fault also arisen. The recent technological advancement suggests the importance of low voltage ride through (LVRT) in wind energy conversion system (WECS).

What is a low voltage wind turbine?

The voltage of the electricity produced by the wind turbine is usually classed as “low”, below 1, 000 V, and is often 690 V. Some larger turbines use a higher generator voltage, around 3 kV, but this is not high enough for economical direct interconnection.

What voltage is a wind turbine generator?

A modern wind turbine is typically equipped with a transformer that increases the generator terminal voltage, usually below 1 kV (e. g. 575 or 690 V), to a medium voltage. The turbine generator voltage is usually classed as “low” (below 1, 000 V) and is often 690 V.

What voltage does an offshore wind turbine use?

Larger offshore turbines may operate at higher voltages, around 3. 3 kV, which also facilitate better transmission efficiency. Despite the common usage of 690 V, some turbines, particularly larger ones, can produce higher generator voltages. During low wind conditions, turbines must still maintain sufficient output voltage for power supply.
