电力数据网络设备运行优化

Optimization of Power Data Network Equipment Operation

为增强电网数据通信的安全性,巩固变电站网络运行的稳定性,需要对电力数据网络设备进行优化,文章详述调度数据设备和传输制造报文规范(manufacturing message specification,MMS)信息交换机的优化方案,涉及路由器限制明文流量的访问控制列表(accesscontrollist,ACL)优化、路由器ACL策略配置书写优化、调度数据设备组网模式优化、MMS交换机级联模式优化以及MMS交换机业务分区优化。除优化后符合调度设计及网络安全原则的方案以外,其余方案结合调控中心平台监视和模拟实验,对优化成效进行验证,结果表明方案实现了电力数据网络的持续健康运行。

In order to enhance the security of power grid data communication and consolidate the stability of substation network operation,it is necessary to optimize the power data network equipment.This paper describes the optimization scheme of dispatching data equipment and MMS switch in detail,involving ACL for router restrictions on plaintext traffic optimization,router ACL policy configuration writing optimization,dispatching data equipment networking mode optimization,MMS switch link redundancy optimization and service zone optimization are also discussed.In addition to the optimized schemes that conform to the principles of power dispatch design and network security,the other schemes are validated for optimization effectiveness through control center platform monitoring and simulation experiments.The results show that the scheme realizes the sustainable and healthy operation of power data network.
