Dispatching control of a public transport substation
Madzia, Adam ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with the dispatching control of public transport substations. It contains a research about companies that are creating dispatching control of substations for public transport and a description of the technology they use. Following chapters contain the designed structure of the whole control system, a description of the individual components which were used in this thesis and the design of the structure of communication interfaces with the definition of individual communication protocols which were used. In the next section there is a simulation of public transport substation created on the PLC and a visualization for HMI panel which represents its local control system. In the following part, the design and implementation of the data storage system was created by using the Firebird database tool and Promotic SCADA software. The last chapter of the thesis contains creation of the SCADA application for the dispatching control.

Information and communication technologies in energetics
Stavinoha, Jakub ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
The thesis is focused on the information and communication technologies used in the energetic. Problematic areas in energetic which are regulation, metering, control of waste minimalizations, expense and maximalization of earnings. These aspects lead to implementing expert systems, which have to process this bulk of information necessary for increasing efficiency and economization of single processes. Systems used in practice have their own hierarchical structure, where every application requires specific access of selection of used components that suit to the application. First of all it is about acceptable device selection in single level of the system: metering and regulation, data acquisition out of the process and informative layer. Suitable choice flowing from previous, already settled up application is possible to reach maximum efficiency of the whole system. In the thesis there are introduced systems used in practice and possibilities of increase the effectiveness of generation, transmission and distribution with ICT usage in distributed power generation. We are mainly talking about upgrade processes joined with power generation of energy, diagnostics, isolation states on the power line and usage of expert systems for distribution.

Autonomous and dispatching control of distributed power generating plants operated in the HV distribution system
Dvořáček, Jiří ; Jurík, Michal (referee) ; Drápela, Jiří (advisor)
Theses focuses on the evaluation of the possible means of active and reactive power control of generating units connected to medium voltage. First part summarizes analysis of Czech Republic medium voltage distribution grid. It summarizes means of autonomous and dispatcher control of generating units with respect to European Comission directive RfG, standard ČSN EN 50549-2 and national implementation PPDS. Following parts provide description of generating unit and distribution grid models used for simulation in PSCAD. Last part focuses on evaluation of results obtained via simulating steady-state scenarios as well as continuous simulation.

Improvements of information flows in road haulage
MEJDA, Vít
The dissertation thesis works out the problematic of increasing quality in information flow in road haulage. The thesis highlights logistic chains of road haulage of both carload freight and colli deliveries. Research project took place in two divisions of the biggest south bohemian transport company ČSAD JIHOTRANS a.s. The specified quality improvement of information flows comes out from implementation of new information technologies. The dissertation thesis is not only the description of new functions of implemented technologies, but it mainly describes consequential changes, which are necessary to perform in order to reach requested improvements.
