WindGuard Certification recently completed a reference project with support from Langer E-Technik. On customer behalf, the two companies retro-fitted an existing test device for Fault-Ride-Through (FRT) tests on power generating units such as wind energy turbines and solar plants, energy storage units and combustion engines.The test equipment enables low voltage and high voltage ride-through (LVRT and HVRT) tests to prove dynamic grid support according to current guidelines such as FGW TR 3 and IEC 61400-21-1 as well as international standards. For this purpose, fault conditions in the public grid are simulated, and the behaviour of the power generating unit is documented. WindGuard Certification and Langer E-Technik have accommodated the entire equipment for performing Fault-Ride-Through (FRT) tests on power generating units in one 40’ container.
