-Abstract
This paper proposes a fault ride-through (FRT) scheme with alternatively employing shunt and series compensation for enhancing FRT capability of the fixed speed wind turbine (FSWT). A combined approach based on shunt and series grid interface topology for one voltage source converter (VSC) is used to enhance FRT capability for the FSWT. The VSC in its shunt interface topology works as a static synchronous compensator (STATCOM) to regulate voltage in normal operation and in light voltage dip. In case of serious grid voltage dip the VSC instantaneously switches from shunt to series grid interface and works as static synchronous series compensator (SSSC) injecting a series voltage through series coupling transformer to compensate the terminal voltage of the wind turbine generator (WTG). The proposed control scheme, utilizing positive and negative sequence controllers, provides a transient management solution for both balanced and unbalanced fault conditions. A comprehensive simulation study using PSCAD/EMTDC simulation program demonstrate the performance of the proposed scheme for enhancing the FRT capability of the FSWT in response to severe symmetrical and asymmetrical grid faults.
