Objective With the rapid development of wind power, the planning and construction of wind farms have become a key research focus. Wake effects as one of the most critical influencing factors, significantly impact turbine performance. This study analyzes the interaction characteristics of multi-turbine wakes to provide insights for optimized wind farm layout.

Method Based on Fast.Farm simulation software, the wake effects in a wind farm consisting of six NREL-5MW turbines were investigated. By varying the spacing between turbines, the output power and aerodynamic performance of the wind farm were analyzed. Additionally, the impact of staggered turbine arrangements on power output was studied.

Result The study finds that increasing the spacing between upstream and downstream turbines significantly improves the power output of the three downstream turbines. Furthermore, while a single staggered turbine configuration does not enhance total wind farm output, staggering multiple downstream turbines lead to a notable increase in power generation.

Conclusion This research examines the effects of adjusting both longitudinal and lateral turbine spacing, as well as staggered arrangements, on power output. The comparative analysis of different configurations provides valuable guidance for optimizing wind farm layouts.
