Modeling of large wind farm systems for dynamic and harmonics analysis

This paper discusses the different topologies of wind turbine generators. An explanation of the basic components of the wind turbine dynamic model is given. The validation of a devloped wind farm dynamic model is illustrated by comparing simulation results and filed test results for a 100 MW wind farm. The paper also explains the modeling of the different elements in the wind farm to perform harmonics analysis. Potential parallel and series resonance problems that can occur in a large wind farm are analyzed. Solutions to mitigate harmonic problems are given. A case study on a 200 MW wind plant is used to explain the procedures of performing harmonic analysis.
