In the master's thesis is clarified remote supervision and control of fixed installations for electric traction on the Slovenian rail network. We described in particular the basic construction elements: contact line, power lines and cable lines, traction substations and control centers.
We presented structure of a local area network of the Slovenian Railways. The local network is used as a basis for data transfer between traction substations and control centers. The basis for managing complex systems are communication protocols, which describe interactions between different components of such systems.
We describe MoudBus, IEC 60870-5-101, IEC 60870-5-104 in NEO, as they depict the behaviour of these kinds of systems at the lowest level. Furthermore, the type of physical connection, bit encoding and other properties of the physical layer as well as medium access control, services and data framing, which are properties of the link layer, are described.
The purpose of control centers is to provide a smooth, safe, reliable and economical operation.
The control center supervision and control of fixed installations for electric traction was set up in 2010. After 10 years, updates were needed. In the update, we also replaced the concept of operation. During the update, we replaced the concept of monitor layouts and the background of the image from gray to black color. We have redesigned the concept of operation of the management center so that we now have a centralized database from which five SCADA clients read data. Each SCADA client has full control over the entire electrified railways line of Slovenia, which means that SCADA clients are equivalent.
