摘　　要：介绍了唐山郭家屯220 kV数字化变电站工程,着重分析了该工程的技术特点和实施方案,指出其主要技术创新点,包括:220 kV线路、变压器测控保护一体化;以分散录波方式解决数字化变电站集中录波的难题;在数字化变电站应用程序化控制;简化开关内部二次回路;以网络化方式实现变压器非电量保护功能;过程层设备实现开关场就地安装。A typical digital substation, Tangshan Guojiatun 220 kV Project, is introduced. The main technical features and implementation scheme of the project are analyzed, including the function of protection, measurement and control integrated into 220 kV transmission line and transformer protection relays, distributed disturbance data recording, the program sequence control in digital substation, simplify the secondary circuit, the no-electrical protection for transformer implemented ＂based on generic object oriented substation event （GOOSE）, the distribute installment of the process level devices on the switchyard.
