Abstract

Low voltage ride through (LVRT) is one of the most important capabilities that modern renewable energy conversion systems should have to support grid voltage during fault conditions. Nevertheless, testing real LVRT scenarios experimentally is challenging. This paper examines the implementation of LVRT studies in laboratory scale. It uses a series inductance to mimic the effect of grid impedance, which makes voltage control possible and visible at the point of common coupling (PCC). Moreover, it analyzes the effects of overvoltage protection (OVP) using chopper resistor, the effects of the controllers, and the effects of faults magnitude and duration on the LVRT performances. A laboratory scale permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) is used to verify the LVRT studies. It is found that the examined LVRT effects influence the application of accurate LVRT studies in laboratory scale experiments.
