Introduction In order to understand the wake loss of offshore wind farm, the simulation results are verified to explore the variation law of offshore wake loss.
Method In this paper, the PARK model was used to simulate the wake flow of a offshore wind farm in South China. The parameters of the model were optimized and the actual power output was verified.
Result The results show that application of PARK model in wake simulation of offshore wind farms basically coincides with the actual power output. When wind turbines with 7D spacing in a certain wind direction, the distribution of main wind wake loss after the second row is about 30%.
Conclusion PARK wake model can simulate the wake loss and calculate the power output in offshore wind farms. Sensitivity calculation of model parameters should be carried out to meet the actual conditions.
