摘要:
发变组保护双重化配置以后，相对于以前的常规保护，对互感器配置、组柜方案、保护出口及其二次接线均有不同的要求。各保护厂家针对双重化配置开发生产的数字式保护装置也各有不同的应用。以四方公司开发生产的CSC-300系列发变组保护装置为例，结合内蒙地区新建300 MW机组保护的标准图设计，就上述问题做了介绍和总结。

Abstract:
Compared with conventional protection for generator-transformer unit, protection configured double sets has different demands in many aspects including transducer configuration, scheme of panel design, protection operating objects and its connecting status in secondary circuit. Microcomputer-based protections produced by dissimilar manufacturers are in different applications. Taking an example of series CSC-300 protection for generator-transformer unit produced by Beijing Sifang Automation Co., Ltd, the paper introduces and summaries above-mentioned different demands and applications, combining standard design of new-built 300MW generator-transformer unit in Inner Mongolian area.
Key words:  generator-transformer unit  microprocessor-based protection  double sets of protection configuration  protection configuration  scheme for panel design
