Some of the traditional power distribution network fault location, isolation, and service restoration (FLISR) tasks were conducted with feeder automation (FA), which is part of the distribution automation (DA) system. Existing FA scheme have issues such as long fault processing time, due to centralized decision making. In this paper, a FLISR scheme for distribution network based on edge computing and 5G is proposed. Three key technologies of the scheme are introduced: ① Edge computing servers with local terminal units (LTU); ② FLISR algorithms with software-defined control and edge-cloud collaboration; ③ 5G integrated with edge computing (MEC). The proposed scheme is the first case with integrated 5G and MEC in DA applications, which can effectively shorten the fault processing time as evidenced by the deployed system’s performance.

In recent years, China's electric power business has been booming, the scale of material procurement of electric power enterprises has been growing rapidly, and the intensity and complexity of electric power material management work have also increased significantly. In order to improve the overall level of material management of electric power enterprises, we should plan for the long term, actively introduce advanced technology and pursue high-quality development. This paper will discuss the feasibility of applying blockchain technology in the field of material management of electric power enterprises, and then propose a design scheme for a new electric power material management system based on blockchain technology for the industry of electric power material management to make reference to.
