Alternative approach for a total integrated secondary installation in MV substations covering all possible and required functions

A simple, flexible and cheap automation concept for MV substations has been developed. The concept consists of a fully integrated system, containing accurate data acquisition, metering, protection and control. It is in line with IEC 61850. The basics of the system were fully type tested during 2004. In 2005 it will be implemented in two substations in order to proof the data acquisition in combination with several central monitoring systems within the company. The next step will be the integration with protection and control in 2006. As from 2007 this system will be used during substation refurbishment.
