Research and Application of Integrated Data Fusion Terminal for Station Area Operation and Distribution Based on Edge Calculation and Software Definition

Abstract

In this paper, we studied the integrated data fusion terminal for distribution area operation and distribution based on edge calculation and software definition. Firstly, the overall architecture of the integrated data fusion terminal for distribution area operation and distribution was constructed, and the software and hardware of the terminal were comprehensively designed. Then, an edge data stream hierarchical storage algorithm and an edge computing resource allocation method based on Deep Deterministic Policy Gradient (DDPG) reinforcement learning algorithm were proposed. In order to meet the capability of edge computing, the resource utilization efficiency, running time and throughput efficiency of CPU were compared and analyzed. The optimal CPU chip was selecited to complete the optimal design of terminal control system. Finally, combined with the field, the terminal was applied. The functions of data monitoring, fault early warning, topology identification and distribution area line loss were realized, which meets the professional needs of marketing and production, reduces the investment cost of power grid equipment and improves the on-site maintenance efficiency.
