Description
technical field [0001] The invention relates to a virtual reality simulation platform system, in particular to a virtual reality simulation platform system for galloping and dance-proof design of overhead power transmission wires. Background technique [0002] Under the action of wind excitation, the ice-coated transmission wire will produce a low-frequency, large-amplitude vibration, which belongs to galloping, also known as galloping. This kind of galloping is generally large in amplitude, long in duration and accompanied by swinging. It will cause great damage to the transmission line, easily cause phase-to-phase flashover of the line, damage to hardware, cause line tripping and power failure, or cause burns to wires, pull down towers, and wire breaks. accidents, resulting in major economic losses. In recent years, 500 kV lines in some areas of China have experienced large-scale ice flash trips, conductor galloping, and tower down and disconnection accidents. , the ice ...
