提出一种110 kV智能站的变压器保护配置方案，并与常见的几种配置进行比较。该变压器保护配置集主保护、后备保护、测控、主变自投、合并单元及智能终端功能于一体，采用主后一体化保护装置就地安装的应用方式。基于IEC 61850-9-2采样传输协议和面向通用对象的变电站事件(generic object oriented substation event，GOOSE)机制，用4台装置实现2台变压器相关所有功能。取消了独立的合并单元、智能终端、主变自投等装置，最大化地简化了变电站网络，降低了变电站建设和维护成本。

This paper presented a local installed transformer protection configuration scheme for an 110 kV digital substation. Different from the conventional configuration scheme, this configuration scheme consists of main protection, backup protection, measurement and control, automatic switching function of transformer, merging unit and smart terminal function. Based on IEC 61850-9-2 sampled value and generic object oriented substation event (GOOSE) network, four devices can achieve all protection functions for two transformers. The configuration can be maximized to simplify the substation network, reduce the substation construction and maintenance costs.
