Abstract

The present disclosure relates to a high-efficiency DC ice-melting device dedicated to wind power lines and a parameter adaptation method thereof. The device comprises: a non-shifting transformer, a diode 6-pulse ice-melting rectifier, an ice-melting switching knife switch, and an ice-melting measurement and control system; The AC input side of the gear transformer is connected to the AC power grid, the output side of the non-shift transformer is connected to the AC input side of the diode 6-pulse ice-melting rectifier, and the DC output side of the diode 6-pulse ice-melting rectifier is connected to the ice-melting switch knife switch. One side is connected, and the other side of the ice melting switch is connected to the wind power line to be melted; When an exception occurs, a protection alarm message is issued. The technical solutions provided by the embodiments of the present disclosure can realize a high-efficiency DC ice-melting device dedicated to wind power lines, and combined with the parameter adaptation (ie configuration) method thereof, can realize efficient and economical melting and de-icing of wind power lines.

Description

technical field [0001] The present disclosure relates to the field of electrical technology, and in particular, to a high-efficiency DC ice-melting device dedicated to wind power lines and a parameter adaptation method thereof. Background technique [0002] Wind farms are usually located in areas rich in wind resources, such as mountain tops, plateaus, and valley mouths. Their transmission lines often pass through ice-covered areas, which are more prone to rain, snow, and freezing disasters than general transmission lines. Ice-covered lines can easily lead to tower collapse and disconnection. , affecting the normal transmission of wind power. Severe icing of wind power lines occurs almost every winter, and it is necessary to implement line thawing on site. In view of the above situation, at present, all wind farms need to conduct anti-icing check of transmission lines before they are put into operation, and ice-melting devices must be equipped for the transmission lines of ...
