Based on conventional static line rating method, the actual current carrying capability of overhead conductors cannot be judged. Due to continuous increment in electricity demand and the difficulties associated with new line constructions, the overhead lines are therefore required to be rated based on a method that should establish their real-time capability in terms of electricity transmission...

In order to achieve reliable and high-speed 10kV power line carrier communications, it is necessary to study the characteristics of channel. Based on the multi-conductor transmission line theory, the chain matrix channel model is established. A lumped parameter model of distribution transformer is proposed from impedance measurement in the frequency range 50-500kHz. The terminal voltages and cu...

In this paper we describe a new method to measure the position of an overhead line in a railway application. The height and stagger of an overhead line can nowadays be measured through a stereo-vision system composed of two line scanner cameras; the existing applications, unfortunately, cause some malfunctioning. In this work we want to test a new method that increases the resolution of wire im...

Abstract Overhead lines for wind power transmission in the southern region have characteristics of large tower-line elevation, across thick ice areas, harsh natural environments, and difficult maintenance. Unpredictable line breakage accidents often occur, affecting stability social supply. This paper designs introduces a technology based on intelligent perception technique online monitoring ea...
