基于电力通信网的高可靠性SDN架构及数据保护策略OACSTPCD
Research on high reliable SDN architecture and data protection strategy based on power communication network
针对变电站中传统电力通信网在各类故障、攻击或突发事件下容易出现网络延时增长、数据质量下降、数据丢失等问题,文中设计了一种以SDN架构为核心技术方案的高可靠性电力通信网数据保护策略.该策略在电力通信控制环路中引入SDN技术,并设计了SDN集中控制架构,以提高在故障发生时的数据保护能力,从而避免了数据资源的浪费、缺失以及耗时过长等问题.同时,还在SDN控制架构的基础上设计了一套ODL控制方案,通过采用该控制方案使得控制环路得到再次优化,由此有效提高了数据质量.最后,对所设计SDN架构下的电力通信控制系统保护策略进行了数据仿真测试验证,通过模拟SDN架构方案的仿真工况,验证了所设计控制保护策略的正确性与可行性.
The traditional power communication network in substation is prone to network delay growth,data quality degradation and data loss in case of various faults,attacks and emergencies,so a high reliable power communication network data protection strategy based on SDN(software-defined networking)architecture is designed.In this strategy,the SDN technology is introduced into the power communication control loop and an SDN centralized control architecture is designed to improve data protection capabilities in the event of faults,so as to avoid waste,missing and excessive time consumption of data resources.An ODL(open day light)control scheme is designed based on the SDN control architecture,which is used to further optimize the control loop and improve data quality effectively.Data simulation testing was conducted to verify the protection strategy of the power communication control system based on the SDN architecture.By simulating the simulation conditions of the SDN architecture scheme,the correctness and feasibility of the designed control protection strategy were verified.
