IOT for PTDE is a typical cyber physical system (CPS), all power transmission and distribution equipment have been digitized and networked. It has the ability of efficient communication between not only equipment to equipment (E2E), but also equipment to human (E2H), which integrate information technologies into power grid by new operation and management model. In this paper, the architecture, function...
Condition monitoring and management system (CMMS) for power transmission and distribution equipments is an important part of smart grid. This paper addresses issues relating to the techniques of CMMS and its application in Yunnan Power Grid. After introducing the basic concepts and essential characters of Intelligent CMMS, many technological challenging issues of it are discussed. And engineering...
This paper summarizes the usual means of network authentication first. Next, a Web security and identity scheme based on session and online table is proposed. The thinking and implementation of the scheme is detailed then. Lastly, the paper analyzes the security intensity of the proposed scheme from various aspects. Either the analysis or the application of the scheme shows that the proposed method...
Abnormal traffic detection is important to network management. This paper aims at the characteristic of multi-hop network, and defines abnormity that traffic-burst after failure. Then the paper presents a fast auto-adaptive traffic-aware abnormal detection method. This method compresses data via efficient histogram, and detects double-size bursts via congregate function. We analyze the status of links...
