数字化变电站的现状与未来

随着数字化变电站的发展以及IEC 61850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。但在目前的基础上数字化变电站的方案如何才能做到在确保现有电网安全性、可靠性、经济性的基础上来建设数字化变电站并兼顾到技术的前瞻性与实现的可行性。根据现有的技术现状与理想数字化变电站的模型的对比,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,并指出了理想的数字化变电站建设是变电站未来发展的必然趋势。

The Actuality and Future of Digital Substation

With the development of new technologies of digital substation and the generalization of IEC 61850 protocol,building digital substation is tending towards project practice.But now,it is a problem how digital substation is built in order to insure the security,reliability and economy of grid,with prospect and realization of technologies included.According to the contrast of technologies actuality to ideal digital substation,IEC 61850 protocol,intelligent switch,electronic transformer and digital measure system are studied,and the scheme of digital substation is expounded.It points out that the ideal digital substation building is inexorable trend of substation in the future.
