Augmentation of fault ride-through capability of PMSG in a wind power plant using resistive SFCL and a new reactive current injection controller

Abstract

This paper presents the study to use the effect of the resistive superconducting fault current limiter (RSFCL) on a wind power plant rated at 50 MW, which can provide an augmentation for the fault ride-through (FRT) capability. The wind power plant consists of the number of wind turbines that each one based on a permanent magnet synchronous generator (PMSG) and a back-to-back full rating converter. The RSFCL by limiting the fault current can decrease the reduction of voltage at the point of common coupling (PCC). It can be improved by adding a new control strategy of the reactive current controller based on the grid code requirements to the grid-side voltage source converter (VSC). Moreover, because of increasing voltage, the active power output of the wind power plant increases, therefore, it can diminish the dc-link voltage in faulty conditions. In this paper, both the thermal and electrical properties of high-temperature superconductor (HTS) are considered. In addition, its modeling coming from the electrical field is done with “Power Law.”
