摘要

高压输电线路的动态增容是目前解决输电瓶颈最经济的方法。传输线的测温误差会影响传输线的计算电流容量。本文采用导体温度模型分析测量误差对最大电流容量的影响，并采用Morgan公式进行比较。为了确定本项目中的PT100温度传感器是否满足上述精度要求，我们进行了温度实验并收集了大量数据。主要通过统计直方图和假设检验对PT100温度传感器的测量误差进行了分析，给出了误差结果，并提出了减小测量误差的建设性方法。

Characteristic Analysis of Temperature Sensor in Dynamic Capacity Increase of High Voltage Electric Power Transmission Lines

Dynamic capacity increase in high voltage electric power transmission line is currently the most economical method for solving electric power transmission bottleneck nowadays. Temperature measurement error of the transmission line will affect the calculated current capacity of the transmission line. In this paper, conductor temperature model was applied to analyze the influence of the measurement error on the maximum current capacity, and Morgan formula was used for comparison. In order to decide whether the PT100 temperature sensor in this project satisfies the accuracy requirement above, a temperature experiment was conducted and a large amount of data was gathered. The measurement error of PT100 temperature sensor was analyzed mainly by statistics histogram and hypothesis testing, and gives the result of error as well as suggests a constructive approach to reduce the measurement error.
