摘要
随着电网的不断发展,110 kV线路在电网中发挥着重要的作用,目前以配置光纤电流差动保护为主。在遵循相关配置原则的基础上,笔者分析了当前110 kV线路采用的几种不同接线形式的情况,并提出相应的保护配置要求。结果表明:在三端T接线路中,需配置三端光纤电流差动保护装置,该类型保护能够适应三侧差动、任意两侧差动的运行方式;对工业用户110 kV供电线路特殊接线形式,有针对性地配置不同的保护装置。该研究成果可为“双碳”背景下部分新能源送出线路的保护配置提供参考和借鉴。
With the continuous development of the power grid,110 kV lines play an important role in the power grid.At present,the optical fiber current differential protection is mainly configured.On the basis of following the relevant configuration principles,the authors analyze several different wiring forms used in the current 110 kV line,and put forward the corresponding protection configuration requirements.The results show that the three-terminal optical fiber current differential protection device needs to be configured in the three-terminal tapped line.This type of protection can adapt to the operation mode of three-side differential and any two-side differential.For the special connection form of 110 kV power supply line for industrial users,different protection devices are configured in a targeted manner.The research results can provide reference for the protection configuration of some new energy transmission lines under the background of“double carbon”.
