摘　　要：根据《继电保护和安全自动装置技术规程》GB/T 14285-2006归纳了发电机变压器组继电保护的主要特点,对发电机变压器组单元接线继电保护配置的部分条款要求作了解释,详细论述了应考虑装设的保护和各种保护出口的设置原则,并对目前电气量保护全双重化存在的问题提出了一些看法和建议,突出强调了发电机变压器组公共保护的主要特点和设计方案。最后,对大型发电机变压器组继电保护的配置和保护出口的设计原则提出了几个值得注意的事项。Based on ＂Technical code for relaying protection and security automatic equipment＂ GB/T 14285- 2006,the features of relay protection for generator- transformer unit are concluded. Partial items of relay ＇configuration for generator- transformer unit connection are explained. The relays to be installed and the configuration rule of various protection outputs are discussed. Some suggestions against the problems existing in present totally dual electrical variables protection are proposed. The main features and design scheme of common protection for generator- transformer unit are emphasized. Several remarkable proposals for the protection configuration and protective trip design rules of large generator -transformer unit are presented.
