Neuro Fuzzy Logic Controlled Parallel Resonance Type Fault Current Limiter to Improve the Fault Ride Through Capability of DFIG Based Wind Farm

Project Code :TEPGCS36

Objective

Main objective of this project is to enhance the overall stability of wind farms and allow them to maintain grid-code requirements and enhance the FRT capability of the DFIG based wind farm.

Abstract

In this project, a Neuro Fuzzy Logic Controlled Parallel Resonance Type Fault Current Limiter (NFLC-PRFCL) is proposed to enhance the FRT capability of the DFIG based wind farm. Doubly Fed Induction Generators (DFIGs) are vulnerable to grid related electrical faults. Standards require DFIGs to be disconnected from the grid unless augmented with a Fault Ride Through (FRT) capability. 

A Fault Current Limiter (FCL) can enhance the overall stability of wind farms and allow them to maintain grid-code requirements. Theoretical and graphical analysis of the proposed method are carried out by MATLAB/Simulink software. The performance of the NFLC-PRFCL is compared with other documented FCL devices, e.g., the bridge type Fault Current Limiter (BFCL) and the Series Dynamic Braking Resistor (SDBR). 

The performance of the NFLC-PRFCL is also compared with that of the existing Fuzzy Logic Controlled Parallel Resonance Fault Current Limiter (FLC-PRFCL). From the simulation results, it is found that the NFLC-PRFCL outperforms its competitors and enables the DFIG to maintain a near-seamless performance during various fault events.
