Secure Data Communications for Controlling Electric Power Stations and Distribution Systems

Abstract

Uninterrupted electric power distribution is vital for modern society. One of the key components is electric power stations and distribution systems. SCADA systems are used for controlling the power stations. SCADA systems have traditionally used propriety communication networks. For added electrical power station security, a video surveillance is required. Current telecommunication networks used for SCADA systems don't support speeds required for real time video. A standard Internet connection does not offer required reliability and security for SCADA communications. Multi-Agency Cooperation In Cross-border Operations (MACICO) project aims to produce a new way of combining multiple telecommunication channels, such as TETRA, satellite and 2G/3G/4G networks. A certain target is to create a single redundant secure and faster data transfer path for SCADA and video surveillance systems. In Finland there is a project starting utilizing new technologies for data transfer thus demonstrating usability and reliability of this new communication method.
