摘　　要：以某数字化变电站改造工程为研究对象,在10 kV母线段增加简易母线保护,并采用GOOSE网络通信机制取代传统保护之间的锁联信号,解决了传统方式下各个出线保护和分段保护与简易母线保护之间存在较多硬开入连线,二次回路复杂的问题,提高了简易母线保护的可靠性,同时解决了原来控制保护系统存在的保护死区、开关失灵等问题。One digital substation reconstruction project is taken as the research subject,where simple bus protection is installed on the part of 10kv bus,and the blocking signal in the traditional protection is replaced by GOOSE network mechanism.Accordingly,the old problems of large amount of hard wiring and the complex secondary circuit have been solved.Meanwhile,this new system has enhanced the reliability of the simple bus protection and solved the problems of protective dead zone and switch malfunction in the conventional control and protection system.
