基于改进WRR算法的智能变电站站内通信队列调度研究

智能变电站中数据通过以太网架构综合信息一体化传输网络进行共享,及时有效的数据交互是确保智能变电站正常运行的重要环节。针对现有的数据优先级调度策略所存在的缺陷,对传统加权轮询算法进行改进,并将其运用于智能变电站综合数据调度中。以220 k V典型智能变电站为例,在OPNET网络仿真软件中建立站内通信模型进行实例仿真。结果表明,紧急情况下,改进后的加权轮询算法可以为高实时性要求报文提供更好的服务。

Research on smart substation inner communication queen scheduling based on improved WRR algorithm

The transmission of network data through Ethernet architecture integrated information share the information in smart substation, and the timely and effective data interaction plays an important part in the protection of the normal operation of smart substation. In view of the deficiency of the existing data priority scheduling strategy, an improvement of the traditional weighted polling algorithm is proposed, which is applied in the smart substation integrated data scheduling. Taking the typical intelligent substation of 220 kV for example, this paper establishes the communication network in OPNET for instance simulation model. Simulation results show the improved weighted round robin scheduling strategy can provide a better service for the high real-time request message in emergency circumstances.
