Design Of Ice Melting Techniques For 35KV Current Collecting Line At Luotuogou Wind Farm

As a clean energy source,wind power has received more and more attention from the country.The construction of wind farms has also continued to expand.The scale has grown and the position in the grid structure has become increasingly important.For wind farms in the Bashang area,the occurrence of ice-covered disasters is particularly prominent,and there is also a large impact on the operation of wind farms.The construction of early wind farms took into account the high wind speed factors.The location of the wind farm was higher or the location of strong air outlets.The sudden encounter with strong winds,heavy snowfall,and white windy weather caused the lines to be covered with ice and covered with snow.This article mainly solves the problem of icing of 35kV collector line in wind farms.Under the support of alternating current ice-melting technology,combined with the analysis of ice melting characteristics to realize the design of 35kV ice-harvesting line ice-harvesting technology scheme to meet the needs of the electricity market.The design of the paper revolves around the 35kV ice-melting technology of the LuoTuoGou wind farm as the theme,from the analysis of melting ice characteristics as the entry point,and as the guideline for the ice-melting scheme of the wind farm collector circuit,under different meteorological conditions from the line The maximum allowable current,the cord-wound current,and the m inimum ice-melting current value are used to explain the relationship between the ice-melting current and the ice-melting time.The dissertation mainly studies the measures to prevent serious ice covering on the insulating parts and wires of transmission and distribution lines,as well as the method of rapid ablation after the ice coating,to safely remove ice,and prevent the grounding,reversed rods,and broken wires of the transmission and distribution lines due to ice coating.In this paper,based on the research and analysis of the icing situation of the 35kV collector line in the LuoTuoGou wind farm,the ice-melting technology scheme of the collector line is determined.
