摘要

针对由不同型号地线组成的长距离架空地线融冰问题

提出了一种长距离多分段架空地线直流融冰方案。研究长距离多分段地线融冰中普通地线及OPGW光缆的接线方式。为满足地线融冰电流与实际需要的融冰电流保持一致

提出了一种地线设计融冰电流计算方法。最后结合桂林站直流融冰装置与黎桂线架空地线具体参数

设计了黎桂线多分段架空地线直流融冰方案

通过PSCAD/EMTDC软件仿真分析与黎桂线地线直流融冰方案的工程应用

证明了该融冰方案的合理性与有效性。

Abstract

A segmented DC ice-melting scheme is proposed to solve the de-icing problem for the long distance overhead ground wire composed of different types of wires. The connection modes of common ground wire and optical fiber composite overhead ground wire in the DC de-icing scheme are analyzed.And a method for computing the ice melting current is presented for the design of the DC de-icing scheme. Consequently

a segmented DC de-icing appraoch is designed for the overhead ground wire of Li-Gui transmission line with consideration of the Guilin substation DC ice-melting device and the overhead ground wire parameters of Li-Gui transmission line. Simulation result via software PSCAD/EMTDC and the actual application demonstrate that the present de-icing approach is feasible and effective.
