Performance Analysis of SCIG Coupled With Wind Turbine with and Without Fault

Abstract

This paper represents the modern investigation on incredible wind energy in real world. In this paper we have
introduced a wind power in a power generation and transmission system alongside the conventional 3 -phase sources and
have simulated its working and performance. The wind power is made to work in tandem with the regular supply at first.
In case of faults occurring in the system wind power is used to act as backup for the original supply. Also in case of extra
power demand in peak time periods, it has been used to complement the power sources thereby maintaining the power
quality and frequency in the system. The aim of this paper is to provide the basic concepts to understand a wind energy
generation system and the way it must be operated to be connected to the utility grid. This also includes simulation of
9MW wind farm power using Squirrel Cage Induction Generator (SCIG) by variable pitch wind turbine. . All these
scenarios have been simulated with the help of the simulation program using MATLAB and its inbuilt components
provided in Simulink library.
