摘要：Uninterrupted electric power distribution is vital for modern society. Secure data transfer between control center and power stations is critical for controlling and protecting power distribution. Supervisory Control and Data Acquisition (SCADA) systems are used for controlling the power stations. SCADA systems have traditionally used a limited propriety communication networks to transfer only control signals between centralized control systems and power stations. To improve security and reliability of an electrical power distribution, a video surveillance is required at power stations and distribution centers. Current telecommunication networks used for the SCADA system does not provide required capacity for real time video streaming. 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 to create a single redundant secure and faster data transfer path for SCADA and video surveillance systems. The project relies on the Distributed Systems intercommunication Protocol (DSiP) that allows combining all kinds of telecommunication resources into a single, uniform and maintainable system. In Finland there is a project starting utilizing new technologies for data transfer thus demonstrating usability and reliability of this new communication method.
