摘要
电力系统的电网建设中,用电负荷的要求对系统的运行方式及接线方式有较大影响,由此产生的T接线路在保护配置及运行方式的规定上也有相应的特殊要求。本文以齐齐哈尔地区电网中较为典型的曙光变三侧光纤纵差保护应用为例,阐述了三侧光纤纵差保护在应用中对系统运行方式的影响,从而为电网安全稳定运行方面的研究提供了实际应用的基础数据。
In the process of power grid construction,Electricity load greatly influences the way of the power system operation and wiring. Tconnection lines has its special requirements on the protection of configuration and operating mode. In this paper, As the example in the Qiqihar region＇s 220kV ShuGuang Transformer substation, described the principle of Three sides of the optical fiber differential protection and the impact on the system operating mode. It provides practical information for the stability of the system.
