Wind generators (WGs) or wind turbine generator systems (WTGSs) are produced by a lot of manufacturers all over the world. Many of them are outside western countries and even if they deliver appropriate technical certification for complete testing of the WGs, it is sometimes necessary to perform testing either after direct buying or after maintenance operations. A check facility or testing bench is necessary in order to verify the foreseen parameters for the correct operating mode of the electric machine. A particular issue arises when it is necessary to change the WG on the basis of power hence the diameter. This research presents a way of designing and building a testing bench for WGs in a range from 10 kW up to 25 kW. More specifically, the bench has been used for testing a 20 kW WG. An appropriate measurement series has been traced out to verify the operating mode of the WG and the bench. A total harmonic distortion has been also evaluated and Energy Production per Year has been determined by applying the Kriging technique.

Abstract
Wind generators (WGs) or wind turbine generator systems (WTGSs) are produced by a lot of manufacturers all over the world. Many of them are outside western countries and even if they deliver appropriate technical certification for complete testing of the WGs, it is sometimes necessary to perform testing either after direct buying or after maintenance operations. A check facility or testing bench is necessary in order to verify the foreseen parameters for the correct operating mode of the electric machine. A particular issue arises when it is necessary to change the WG on the basis of power hence the diameter. This research presents a way of designing and building a testing bench for WGs in a range from 10 kW up to 25 kW. More specifically, the bench has been used for testing a 20 kW WG. An appropriate measurement series has been traced out to verify the operating mode of the WG and the bench. A total harmonic distortion has been also evaluated and Energy Production per Year has been determined by applying the Kriging technique.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
