Impact of New Technological Solutions on Power System Process Information

The importance of process information in power system is significant. Wide technological developments of microprocessors at the end of the last century lead to the introduction of intelligent electronic devices (IED) in power system. Classical secondary equipment (protection, measurement and control) lacks communication capabilities so it communicates via remote terminal unit (RTU) with supervisory control and data acquisition (SCADA) system. Introduction of IEDs with embedded communications enabled vertical and horizontal multidimensional data exchange between secondary devices. Standard based communication solution solved the primary obstacle for unambiguous data exchange between different secondary equipment. Traditional approach for managing the power system is based on the assumption that each basic function has its own secondary equipment for data acquisition and processing of data. Introduction of new IED opened the possibility for new concept of multidimensional data integration and information exchange. This paper shows basic concepts for creation of new process information model.
