摘要
指出传统的35 kV变电站不设置母差保护,但是,随着电力负荷及运行方式的快速发展,供配电网需要配置智能化的母差保护。结合变电站综合自动化装置,采用基于IEC61850的GOOSE的逻辑判断元件,可以顺利实现母线差动保护,有力保障了供配电网的安全。
It is pointed out that traditional 35 kV substation is short of busbar differential protection,but in recent years,with the rapid development of power load and operation mode,power supply system needs to be configured with intelligent busbar differential protection.Combining with automation devices in substation,using logic elements based on GOOSE of IEC61850,busbar differential protection can be implemented smoothly,which could guarantee the security of power supply and distribution system.
