摘要
DTLR (Dynamic Thermal Line Rating)是一种对现有电力线路进行监测和动态升级的技术。本文利用GPS测量架空导线垂度来评价DTLR。利用GPS接收机BT359测量了440V配电线路架空导线垂度，确定了不同气温下的DTLR。利用最小二乘参数估计和小波分析方法对GPS原始高度测量结果的固有误差进行了减小，得到了更精确的高度测量结果。
Evaluation of DTLR of power distribution line from sag measured using GPS
Dynamic Thermal Line Rating (DTLR) is used to monitor and dynamically upgrade the existing power lines. The overhead conductor sag measurements using GPS has been used to evaluate DTLR in the present paper. GPS receiver BT359 has been used to measure overhead conductor sag of 440V power distribution line and DTLR has been determined at different air temperatures. The inherent error in raw altitude measurements obtained by GPS has been reduced using Least Square parameter estimation and wavelet analysis to obtain more accurate altitude measurements.
