基于CPR1000堆芯建造的核电厂已经开始采用数字化集散控制系统（简称DCS），对全厂进行集中管理和分散控制。500KV开关站及其配电装置的网控系统（简称NCS）作为与DCS接口的重要电气系统，在早期的CPR1000核电厂两者之间均采用硬接线的方式传递信号，随着电站设计深入以及通讯技术发展，阳江核电厂DCS与NCS首次采用IEC60870-5-104通讯传递信号。本文介绍了核电厂DCS与NCS通讯应用实例，进而通过试验验证该应用的正确性以及提出优化建议。

Distributed control system (DCS) has been applied in nuclear power plant (NPP) based on CPR1000 reactor,which make the central management and distributed control for whole plant.The control equipment of 500KV main switchyard-EHV switchgear is network control system (NCS).DCS and NCS adopt hardwired to trans-mit signals in early CPR1000 plant,due to in-depth design of plant and development of communication tech-nology,DCS and NCS adopt IEC60870-5-104 protocols to transmit signals in Yang Jiang NPP for the first time. The application example of DCS and NCS communication based on IEC60870-5-104 is introduced,furthermore,the correctness of application is validated by test and optimization suggestion is provided accordingly.
