Abstract

How serious damages to the transmission lines and how safe transportation of electric energy are decided by the galloping extent of transmission lines. Random wind load due to the air flow, the temperature thermal stress as a result of the changed temperature, electromagnetic forces because of transmission lines current are important factors which lead overhead transmission lines to gallop. This article provides how to simulate random wind load, how to load thermal stress, how to simplify the electromagnetic force. In the last article, according to the specific parameters we simulate all the loads and analysis of loads.
