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.
