Abstract

Nowadays in the electricity system several challenges have been appeared that system operators have to cope with. One of the major challenges is to increase the transmission capacity of the overhead lines (OHL), while maintaining the safety and security level of the network. Dynamic Line Rating (DLR) by monitoring the real-time environmental parameters next to the conductor is a promising and cost-effective way to use the existing infrastructure with higher efficiency. There are several different deterministic DLR models in the international literature, but there are also other approaches based on soft computing or Monte Carlo simulations for the calculation of transmission capacity. The aim of this paper is to demonstrate the operation of the different models by presenting a real case study.

动态线路额定值计算的不同方法
在当今的电力系统中,出现了一些系统操作员必须应对的挑战。在保证电网安全水平的同时,如何提高架空线路的传输容量是电网建设面临的主要挑战之一。动态线路评级(DLR)通过实时监测导体附近的环境参数,是一种很有前途的、经济有效的方法,可以更高效地利用现有的基础设施。国际文献中有几种不同的确定性DLR模型,但也有其他基于软计算或蒙特卡罗模拟的方法来计算传输容量。本文的目的是通过一个真实的案例研究来展示不同模型的运作。
