摘要:
凭借高可靠性、高利用率、高可扩展性的优势,云技术架构正成为当前计算机系统部署时采用的主流技术途径.作为由大量功能单元组成的计算机系统,智能变电站更需要高可靠性的系统运行环境为实时业务的处理提供保障.在实现传统架构可靠性部署策略的同时,云技术架构基于虚拟化技术和软件定义网络(SDN)所实现的资源冗余和备份切换等策略能够进一步提升系统的可靠性.成功流法(GO法)根据系统各节点之间的数据交互关系完成可靠性评估模型的构建,将系统各组件的可靠性指标代入模型中即可获得可靠性评估结果.对比相同规模智能变电站在不同实现架构下的评估结果,得出云技术架构对智能变电站系统可靠性的提升优势.
Abstract:
With the advantages of high reliability,high availability,high scalability,cloud technology architecture is becoming the ma-instream approach of the current computer system deployment.As a computer system composed of a large number of functional units, the smart substation needs more reliable system operating environment to ensure the real-time operation of real-time services.At the same time of realizing the reliability deployment strategy of the traditional architecture,cloud technology architecture which uses the resource redundancy and backup switching strategy implementation based on the virtualization and software defined network (SDN) can further improve the reliability of the system.Successful flow method(GO method) can build the model of system reliability eval-uation according to the data transactional relationship between the nodes in the system.By taking the reliability index of system com-ponents into the model,the reliability assessment results of system will be gotten.Comparing the assessment results of the different smart substation architecture implementation under the same scale,cloud technology architecture has the advantage of improving smart substation system reliability.
