摘　　要：为解决风电主动支撑和运行控制网络在实时性和可靠性方面所面临的挑战,满足电网调度响应时间要求,针对多业务、大流量通信场景,提出了一种基于时间敏感网络(time-sensitive network,TSN)技术的新型网络模式,通过优化算法对各业务通信时隙进行分配,实现单时间点单业务通信,从而保障业务通信的实时性和可靠性。实验结果表明,在多业务通信情况下,所提时隙算法可以有效分割业务传输间隙,控制各业务延时抖动,提高业务实时性。因此,风电机组通信网络从传统的“尽力而为”型以太网转变为时间敏感网络,避免多业务通信资源拥塞,满足重要数据通信确定性和及时性的需求,提升风电机组主动支撑能力。This paper aims to achieve real-time and reliable active support and operation control networks of wind turbines and meet the response time requirements of power grid dispatch.To meet the demands of multiple-service and high-traffic communication,this paper proposes a new network model based on time-sensitive network(TSN)technology.Through an optimized algorithm,the communication time slots for each service instruction are allocated,enabling single-point-to-single-business communication and ensuring real-time and reliable business communication.Experimental results show that under multi-service communication situations,this slot allocation algorithm can effectively divide the transmission intervals between services,control the delay and jitter of each service,and improve the real-time performance of the business.Therefore,the wind turbine communication network is transformed from a traditional“best effort”type Ethernet to a TSN,which can avoid resource conflicts in multi-service communication and satisfy the needs of deterministic and timely important data communication,improving the active support capability of wind turbines.
