摘　　要：在“碳达峰、碳中和”目标推动下,风力发电成为重要的可再生能源技术,对能源结构优化和环境保护产生显著影响。在该能源转型的关键领域,风电系统的建模与仿真对系统的安全运行至关重要。首先对大规模直驱风电场进行了基于Meteodyn WT软件的流场仿真分析,分析了风电场特定布局下的风功率密度和湍流强度,验证了风电场内各机组排布的合理性。随后通过DIgSILENT/PowerFactory软件对大规模永磁直驱风力发电系统进行建模,并在软件环境中对风电场机组切机操作和电网侧三相短路等风电场常见故障的系统响应进行了暂态仿真。该研究对理解风电场布局优化、风电系统动态行为分析、优化控制策略具有重要意义。暂态仿真结果表明,该模型能准确模拟风电场中的多种故障类型,并为风电场的规划、设计和安全稳定运行提供有效工具。Driven by the goal of peaking carbon emissions and achieving carbon neutrality,wind power has become an important renewable energy technology,which has a significant impact on energy structure optimization and environmental protection.Modeling and simulation of wind power systems are crucial for the safe operation of the system in this critical area of energy transition.This study first conducted flow field simulation analysis on a large-scale direct drive wind farm based on Meteodyn WT software,analyzing the wind power density and turbulence intensity under a specific layout of the wind farm,and verifying the rationality of the arrangement of each unit in the wind farm.Subsequently,a large-scale permanent magnet direct drive wind power generation system was modeled using the DIgSILENT/PowerFactory software,and transient simulations were conducted in the software environment to investigate the system response to common faults in wind farms,such as turbine shutdowns and three-phase short circuits on the grid side.This study is of great significance for understanding the optimization of wind farm layout,dynamic behavior analysis of wind power systems,and optimization control strategies.The transient simulation results show that the model can accurately simulate various types of faults in wind farms and provide effective tools for the planning,design,and safe and stable operation of wind farms.
