In this study, the depth-averaged flow equations for wind farm simulation on the complex terrain are presented. The equations are derived by integrating the original 3D flow equations over the height of the channel depth. This approach reduces the equations from 3D to 2D and reduces the elapsed time of CFD simulations from hours to minutes. Thus, it is very practicable modelling method in real time design work. 2D CFD simulations with depth-averaged equations are compared with full 3D models for the Lillgrund wind farm. The simulation results show that the 2D model predicts with relatively good accuracy the velocity and power behavior. In future, this method will be used for wind farm layout optimization on the complex terrain.
