数字化变电站技术应用

随着数字化变电站的发展,以及IEC61850协议的不断推广,数字化变电站的建设已由理论研究阶段走向工程实践阶段。介绍了国内首座220kV数字化变电站——杜尔伯特变电站,对IEC61850协议、智能开关、电子式互感器、数字式计量系统进行了分析,阐述了现阶段数字化变电站的实施方案,分析了数字化变电站技术较常规站技术的先进性,论述了建设该数字化变电站的安全性、可靠性以及经济效益和社会效益,并指出了数字化变电站建设是变电站未来发展的必然趋势。

Technology of digital substation

With the development of digital substation and extend of IEC61850 protocol,the digital substation has put into engineering practice. The first 220 kV digital substation in China,Duerbot substation,is introduced. The application of IEC61850 protocol,intelligent switch,electronic transformer and digital metrology system in the substation is analyzed,and the implementation scheme at this stage is expounded. Compared with routine substations,the superiority of digital substation is analyzed. Based on discussion of the security,reliability,economic effect and social effect,the digital substation is regarded as the development trend in future.
