基于容器调度架构的录波信息主站系统的设计

Design of Wave Recording Information Master Station System Based on Container Scheduling Architecture

随着电网规模的扩大和运用新技术设备的增加,录波信息呈现出海量、异构和骤发等特征,引起传统录波信息主站系统处理延时及可靠性差等缺陷。文章分析了现有防控措施在技术和管理层面的短板,提出了以容器原理改进录波信息主站系统调度器工作机制的设计方案,通过将录波信息的业务逻辑细粒度化后解构成一系列子任务,再分别同物理主机虚拟量化后的资源进行非亲和性匹配成独立容器,达到多态运行和并发处理的效果。给出了故障域隔离方法和以K-means算法提升容器匹配效率的优化措施,改善了主站系统的整体动态平衡。在云南电力调度控制中心的运行案例证明了系统在处理海量、异构和骤发等极端录波信息时具有突出的性能优势,且可靠性明显提升。

With the expansion of power grid scale and the application of emerging technology and equipment,the wave recording data presents massive,heterogeneous and sudden bursts,which cause defects such as delays and poor reliability of the traditional wave recording information master station system.This paper analyzes the shortcomings of the existing prevention and control measures at the technical and management levels,and proposes a design scheme to improve the working mechanism of the wave recording information master station system scheduler based on the container principle,and solves the problem by fine-graining the business logic of the wave recording data.A series of subtasks are formed,and then the non-affinity matching of the virtual quantized resources of the physical host is performed into a separate container to achieve the effects of polymorphic operation and concurrent processing.The fault domain isolation method and the optimization method of improving the container matching efficiency by K-means algorithm are given,and the overall dynamic balance of the master station system is improved.The operation case of Yunnan Electric Power Dispatching Control Center proves that the system has outstanding performance advantages in dealing with massive,heterogeneous and sudden wave recording data,and the reliability is obviously improved.
