Dynamic line rating (DLR)technology of the power transmission line can dynamically raise the transmission capacity of existing conductors and improve the economical efficiency of the operation of the electric power system without constructing new lines.This paper presents a dynamic line rating (DLR)system based on the conductor catenary angle,whereby the conductor temperature is calculated by using conductor catenary angle and wind deflection angle.Then,based on conductor temperature model (CTM), dynamic current-carrying capacity of the conductor is calculated by using conductor temperature,ambient temperature,solar radiation and conductor load.The system hardware design and functions of the modules are elaborated in detail.The feasibility of the system is verified through field tests.
