MODEL VALIDATION AND VOLTAGE DEVIATION ANALYSIS OF AN EXISTING WIND FARM USING HIGH FIDELITY REAL TIME DIGITAL SIMULATION

This paper reports on the validation of a high-fidelity transient model of an existing wind farm with directly grid connected fixed-speed induction generators implemented on a real-time digital simulator. The model will be used to test the controller hardware of a novel STATCOM, which is planned to be field-tested at the wind farm location, in a hardware-in-the loop setup. The model is described in detail, including the control system model implemented for a realistic replication of the wind farm operation. Comparisons of simulation results with field data, both at the steady state and during transients, are used for validation. In addition, the paper provides insight into the effect of aggregating a large number of turbines into a single equivalent model which is often necessary to reduce the computational burden associated with high fidelity transient simulations.
