A Novel Crowbar Protection Technique for DFIG Wind Farm during Fault Ride Through

This paper proposes a terminal crowbar protection technique for Doubly Fed Induction Generators (DFIG) to protect the rotor converter and enhance network stability during grid disturbances. Simulation test using MATLAB-Simulink toolbox is implemented on a 9 MW wind farm exports its power to 120 KV grid. The simulation is performed using different values of crowbar resistances. The variations of...

Modelling and Simulation of a Transformer With Inter-turn Fault Including Saturation Effect and Variable Fault Parameters

This investigation deals with a mathematical model for a distribution transformer including saturation effect. To this end, the equations related to a three phase transformer are specified and the effect of an inter-turn fault is included. Naturally by applying an inter-turn fault the inductance and resistance matrix will change. Thus, unknown quantities of inductances and resistances for compl...

Inter-Turn Fault Detection in Power transformer Using Wavelets

Detection and removal of incipient faults in power transformer winding is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. This research article presenta a new, simple and incipient fault detection technique, which is based on symmetrical component approach. Using this protection technique, it is possible to detect minor turn-to-turn f...

Inter-turn Short Circuit Fault Diagnosis of Induction Motors Using the Svm Optimized by Bare-bones Particle Swarm Optimization

In order to accurately recognize the stator winding inter-turn short circuit fault of induction motors, a novel method for fault diagnosis was proposed based on a bare-bones particle swarm optimization algorithm (BBPSO) and support vector machine (SVM); and feasible diagnostic steps were also introduced. In this method, the feature vector of induction motor in different conditions was extracted...
