Preliminary discussion on design of intelligent overhead transmission line in smart grid

摘要

According to the composing of the on-line monitoring system for overhead transmission line, the essential aspects of design technology are put forward. Based on the survey of the security threats to overhead transmission line, the designing principles are constituted. And then, the collocation of online monitoring equipment and the technical solution of data transmission are schemed. The outline of intelligent evaluation and diagnosis system is sketched. The mode of the power supply for the online monitoring equipment and communication device is also commended.
