用于计算循环和应急电流电力电缆额定值的方法已经详细阐述多年，并且已经基于阶跃函数的应用以IEC标准的形式标准化。为了达到更好的精度，已经开发了一种基于有限差分方法的计算机方法。本文提出的计算方法为在循环荷载计算中准确计算导线温升提供了可靠的依据。此外，它提出了一个压缩-减压的方法来评估导线的温升，所造成的矩形电流脉冲在日常循环负载的应用。
The method for calculating cyclic and emergency current power cable ratings has been elaborated for many years and has been standardized in form of IEC standards based on the application of a step function. To achieve a better accuracy, a computer method has been developed, based on finite difference approaches. With the propose procedures, this paper provides a sound basis for the accurate evaluation of temperature rises of conductor in cyclic load calculations. In addition, it proposes a compression-decompression approach for evaluating the temperature rise of the conductor, caused by the application of rectangular current pulses in daily cyclic load.
