谈高压直流输电线路继电保护技术研究

Research on Relay Protection Technology of HVDC Transmission Line

在电力系统运行期间,继电保护装置是不可缺少的,其有利于确保电力系统稳定运行。当电力系统发生故障隐患以后,通常会引起不良的现象,具体表现为元件受损、供电稳定性下降以及系统性能得不到有效发挥,造成了大范围的停电现象,产生了巨大的经济损失。该文主要探究了高压直流输电线路继电保护技术的具体应用情况。

During the operation of the power system, relay protection device is indispensable. On the one hand, it is conducive to ensure the stable operation of the power system. When there are hidden faults in the power system, it will usually cause adverse phenomena, which are manifested in the damage of components, the decline of power supply stability and the failure of system performance, resulting in a wide range of power outages and huge economic losses. In this paper, the specific application of relay protection technology for HVDC transmission lines is mainly explored.
