“…For example, the wind speed varies greatly along the transmission line of the mountain outlet and the transmission line of southern coastal area where typhoons often occur [5,6]. The conductor temperature is affected by the meteorological conditions, and the line parameters show a nonuniform distribution characteristic [7].…”

“…In [11], the transmission line is divided into segments of equal length. In [7] and [10], the transmission line is divided by the division model based on ambient temperature. On the basis of these studies, this paper proposes a line division model based on the wind speed along the line, dividing the line into multiple segments.…”

Abstract-In the spatial dimension, the variation of the wind speed along the overhead transmission line makes the conductor temperature and line parameter show a nonuniform distribution characteristic, which has an important influence on the operating status of the system. In order to describe the actual situation more accurately, a line division model based on the wind speed variation along the line is proposed. This paper proves the application value of the model by using a typical 4-bus system. From the two aspects of the power flow and maximum power transmission capacity, we contrast the line division model with the traditional models, indicating that the division model is closer to the actual situation of the system.

“…When the transmission line load was short circuited or broken, the influence of transmission line segmentation model on the spectrum was analyzed in [7]. The line segmentation method was provided based on frequency and temperature in [8] and [9,10] respectively, which were carried out in hardware experiment at power system laboratory in Drexel University. These researches focus on the influence of the frequency and temperature segmentation on the system load flow wave attenuation and phase changes.…”

Abstract-The temperature variation throughout overhead transmission lines has an important effect on the line operation. In order to describe the actual operation of transmission lines more accurately, this paper proposes a line segmentation method based on temperature distribution at different locations. Taking the actual transmission line of Shaanxi Province as a test case, the influence of the different temperature calculation methods on the maximum transmission power of lines is studied under the lumped parameter model and the distributed parameter model, respectively. It is shown that the transmission line model considering nonuniform temperature distribution at different locations is more accurate for studying the operating state of the system.
