摘　　要：为解决粤西海上风电集群与火电打捆送出的同步稳定问题,首先研究了风火打捆送出系统的同步稳定特性和影响因素,然后提出了提高风火打捆送出系统风电渗透率和同步稳定特性好的风电机组优先发电的运行方式优化策略。最后构建了风电场集群整体硬件在环接入的实时仿真系统进行验证,仿真结果表明所提出的同步稳定性提升策略可以提高风火打捆送出系统稳定极限,有力提升了风电并网消纳率和电网安全稳定水平。In order to solve the synchronous stability problem of bundled transmission of offshore wind power cluster and thermal power in western Guangdong,firstly the synchronous stabilization characteristics and influencing factors of the wind-thermal bundled system are studied in this paper,and then the optimization strategies of operation modes for improving wind power penetration rate of wind-thermal bundled system and giving priority to wind turbines with good synchronous stability characteristics are proposed.Finally,a real-time simulation system of wind farm cluster hard-ware-in-the-loop access is constructed for simulation verification,and the simulation results show that the proposed synchronous stability enhancement strategy can improve the stability limit of the windthermal bundled system,which strongly improves the rate of wind power on-grid consumption and the level of grid security and stability.
