Abstract

This paper discusses Substation automation using IEC61850 protocol. The IEC61850 is a part of International Electro-technical commission's Technical committee 57.(TC57) architecture of electric power systems. The protocol is able to overcome many technical limitations of the existing network technology. IEC61850 is an innovative approach that requires a new way of thinking with respect to substation automation that will result in improved performance and economic operation of power system.
