Validation of power factor regulation of a wind turbine

Abstract

The correct power factor regulation of wind turbines is a necessary step for the regulation of the power factor of a wind farm. When the regulation of the reactive power does not correspond with the fixed references in the operation of a wind farm, it is necessary to check whether all the involved elements are working correctly. One of the, most important elements of a wind farm is the wind turbine itself. This article shows how to determine and validate the power factor regulation through the use of a wind turbine. We are dealing with a machine whose manufacturer went bankrupt, and following his disappearance the existing documentation does not allow one to directly draw reliable conclusions. The problem associated with the determination of a practical model on the basis of the measurements realized on the real machine is presented. For machines with technical support from the manufacturer, the presented study can be useful to improve the working of the wind farm. The conclusions are valid for both contrasting and evaluating the machine under study and any other machine.
