Application ofmulti‐stepbridge‐type fault current limiter for faultride‐throughcapability enhancement of permanent magnet synchronous generator‐based wind turbines

Abstract: This study presents a new Multi‐Step Bridge‐type Fault Current Limiter (MSBFCL) for Fault Ride‐Through (FRT) capability enhancement of Permanent Magnet Synchronous Generator (PMSG)‐based wind turbine. In this structure, multi‐resistors in parallel with the Insulated‐Gate Bipolar Transistor (IGBT) switches are used to provide a controllable discrete step resistance. Considering the voltage sag depth at the Point of Common Coupling bus, the MSBFCL inserts the suitable limiting resistance in the faulted line path… Show more

“…In [7], a comprehensive review of LVRT methods is done in two general categories: (a) high cost, using external devices; and (b) low cost, modifying control circuit of back-to-back converters and pitch angle. External devices that improve LVRT include FACTS devices [8], the braking chopper system [9,10], the fault current limiter (FCL) [11,12], and the energy storage system (ESS) [13] utilized at the common coupling point (PCC), dc-link, grid side, and dc-link, respectively. In addition, many studies have been performed in the field of improving back-to-back converter control circuits [14], including the use of active current droop in the MSC controller [9] as well as changing control functions between MSC and GSC [15].…”

“…In [ 18 ], a multi-step braking resistor is proposed to enhance the FRT performance of fixed-speed wind turbines. In [ 19 ], a multi-resistor BFCL (MRBFCL) is proposed to mitigate the PCC voltage under different voltage sag levels. In this configuration multi resistors has been used instead of single resistor in the conventional BFCL in [ 20 ].…”

“…In this configuration multi resistors has been used instead of single resistor in the conventional BFCL in [ 20 ]. It is implemented to the DFIG [ 19 ] and permanent-magnet synchronous generator (PMSG)-based [ 19 ] wind turbines for enhancing the FRT, respectively. Authors in [ 21 ] presents a dynamic multi-cell BFCL to compensate the PCC voltage of wind farms.…”

“…This compensates for the voltage sag at the DFIG terminal to enhance the FRT under whole conditions. In addition, this structure without the series transformer is used for connecting the converter-based DG unit to the grid [28]. However, BFCLs require a high current-rating DC reactor and semiconductor switches due to the flowing fault current amplitude from them.…”
