Influence of modeling pitch angle controller on transient behaviour of fixed-speed wind farm

This paper studies the influence of modeling the pitch angle controller on the transient behavior of a grid-connected wind farm subjected to electrical and mechanical disturbances. Two fixed-speed grid-connected wind farms are introduced based on radial power network for this study. The first wind farm is connected to the grid through transmission line and second one directly connected to the grid without transmission line (strong grid). Time domain simulations of two wind farms, using PSCAD have been performed to show the importance of including the pitch angle controller model in the simulations of the fixed speed wind farms.
