摘要
随着光纤技术在电力通信领域的广泛应用 ,已使利用光纤通道传输继电保护信息成为现实。由于通道类型的不同 ,必然会引起保护配置上的变化。文中在简单介绍一种专门适用于光纤通道的2 2 0 k V线路继电保护装置的基础上 ,为实现 2 2 0 k V线路保护的双重化 ,对采用光纤通道后2 2 0 k V线路保护提出的 2种不同配置方案进行比较 。
Since optical fiber technology has been widely used in the field of power communication, the protective relaying of optical fiber path based signal transmission has become a possible selection. Protective relays vary as the types of the paths vary. This paper introduces a specialized 220 kV line protective relay With optical fiber path. Two protection schemes are compared in order to realize dual protection on the 220 kV line and the better scheme is selected.
