FRT Tests Considering Time to Market Requirements.

Fault ride-through (FRT) tests at wind turbines but also at other renewable generation units are required by grid codes since many years. In the past, mainly technical issues of FRT-tests were relevant, to simulate most realistic voltage dips. Today not only voltage dips are required, but also voltage swells and other requirements are also relevant. Apart from the new technical challenges, nowadays the time to market for new developed wind turbines is more and more critical for the manufacturers. Thus, also the testing period of the FRT capability of the wind turbine should be as short as possible. FRT test campaigns must be quick and easy to manage. They have to be spontaneous and affordable from a commercial point of view. From a physical and electrical point of view, the test system should be realistic and designed in such a way that it can be modeled. After the decision to carry out an FRT test for a wind turbine, there are many organizational and practical things to arrange. [ABSTRACT FROM AUTHOR]
