Safe and reliable communication technologies are the key to transmission line monitoring system. Currently, most of system use public network to communicate, condition monitoring data are difficult to transmit to the master station when signal is weak or no. To solve this problem, this paper proposes converged communication mode, that is public network and optical fiber converged. Based on the optical...
Deep integration of information and communication technology (ICT) brings insecure risk to power system operation. A risk assessment approach of power grid considering the reliability of information system was presented. The influence of information system on the action of protection was analyzed firstly. The reliability model of information system was established. Then the evaluation index, including...
A general description and the protection technologies of the spacecraft power system in terms of deep-space explore, global navigation and earth remote sensor and so on are presented. Base on these, protection system using LCL of spacecraft power system is introduced and some kinds of protection system based on LCL are analyzed and compared. The characteristics of these topologies are summarized and...
How to determine the optimal number of response categories for a rating scale has been debated for more than 100 years and has not yet been solved thoroughly. This study aims to provide an approach to determine the issue for stimulus-centered rating scale. We are one of the first to develop an integrated discrimination function of scale width and the number of stimuli, by integrating the findings...
