1、The aerodynamic performance of an actual wind turbine system is studied by means ofparameter estimation.This is approved applicable to the case with strong noises.Thenonlinearity of the system is considered in the derivi

2、ng of state equations.The aerodynamicperformance of the system can be obtained from the data ae-quired in a short time.Such a newmethod on the research of aerodynamic performance for the wind turbine system is suggested

3、tobe used to the similar cases.
　　DFIGs are mostly used in wind farms connected to the grid and they must meet therequirements provided by the power system.The influence of wind power is of great importanceas it tells

4、 us the behavior of the power system that whether the system will be able to work in aproper manner aider it is integrated with the wind farm.Several softwareare available to study thebehavior of wind power on powers sys

　　This thesis will focus on the influence of wind power on the power system stabilityDFIG aremostly used during the installation of wind power.In this thesis as we have to study Theinfluence of wind power on the

6、power system stabilityso during the modeling process variablecurrent source is used in place of the DFIG to make the work simple.A three phase currentsource is used to inject the current into the power system to control
