摘　　要：针对目前变电站施工网络中的计算延时高、计算资源浪费严重等问题,采用边缘计算技术在变电站施工网络终端附近进行计算,提高变电站施工的效率减少施工成本。提出基于优先级和加权算法的计算资源分配方法对计算资源进行分配,首先对计算任务的优先级进行排序,然后通过计算资源和归一化系数来设定加权值对每个任务进行计算资源的分配。采用Kata Containers来代替普通的虚拟机,Kata Containers具有成本低、延时低等特性能够让边缘计算技术在变电站施工网络中发挥更大的作用。将所提计算资源分配方式与平均分配和按需分配进行对比,试验表明,在相同的时间延时下,所提计算资源分配方式的能量消耗相比平均分配降低了99.36%,能量消耗相比平均分配减少了85.24%。In view of the high calculation delay and computing serious waste of resources in the current substation construction network, adopt the introduction of edge computing technology to calculate near the terminal of the terminal substation construction network to improve the efficiency of substation construction and reduce construction costs. A computing resource allocation method based on priority and weighting algorithm is proposed to allocate computing resources. First, the priority of computing tasks is sorted, and then the weighted value is set by computing resources and normalization coefficients to perform computing resource allocation for each task. Using Kata Containers instead ordinary virtual machines, low cost and low latency of Kata Containers, enable edge computing technology to play a greater role in the construction network of substations. Comparing the calculation resource allocation method with the average allocation and the on-demand allocation, experiments show that under the same time delay, the energy consumption of the computing resource allocation method was reduced by 99.36% compared with the average allocation, and the energy consumption was reduced by 85.24% compared with the average allocation.
