High Voltage Transmission

With the rapid development of Chinese economy construction, hv transmission line has become the main channel for long-distance power transmission and also the most basic conveyance systems and infrastructure for industrial and mining enterprises. The major coal mine fields in China have hv transmission lines passing above. Coal mining subsidence has an important influence on the line tower. So it is important to study the High-voltage transmission line tower to ensure its safety. In this paper, the model is a High-voltage transmission tower. The mechanical analyses for the tower under different boundary conditions are made by finite element simulation. The results can be used as reference for the design of high-voltage transmission line tower in mining area.

High Voltage Transmission

In the high-voltage transmission line system, the accidents have often occurred, and as a result of power line icing accidents are particularly prominent. In this paper, the author presents a DSP-based image monitoring of high voltage transmission line method. This method is use of high-voltage transmission tower-lines camera to collect the high voltage transmission line image in real time, and directly processing the image in DSP. If wires normal, it will not send pictures to the center and if the abnormal occurred, it will calculate the thickness of ice covering wires, converting the image to JPEG. This article designed and implemented the DSP-based image monitoring of high voltage transmission line algorithm exception, run successfully in the simulation and emulation system which can be used for monitoring of high voltage transmission line icing conditions online.
