The Method and Implementation of Icing and De-icing at Xuefeng Mountain Natural Icing Station

This paper introduces the basic situations of the natural icing station on Xufeng Mountain built by the state key laboratory of power transmission equipment & system security and new technology of Chongqing University, and explains the implementation methods of icing/de-icing at this station in a detail way. It is proved that this icing/de-icing method is feasible after over 3 years operation. The icing type and shape under natural environment is related to ambient parameters, conductor types, and distance between conductors and ground; the ice melting time under natural environment is determined by de-icing current, conductor types and environment factors. The research achievements can provide the power system with technology supply for keeping from icing disasters and lowering loss.
