Electricity Meters Utilization for Advanced Monitoring and Control of the Power Distribution Systems
Bernát, Jan ; Pithart, Jan (referee) ; Drápela, Jiří (advisor)
This thesis deals with a research of static meters manufactured nowadays usable in systems of smart metering. Static meters and their functions are described in terms of their internal organization, metrology and wiring. Emphasis is given to the description of new functions (detailed measuring, calendar, disconnector, communications etc.) which could not be used with induction meters and to requirements for measuring, for expenditure control, for safety of meters and for the concept description of smart grids. In a practical part of the thesis particular systems of smart metering will be described – AMR, AMM, AMI and their advantages and benefits during their deployment. The thesis includes also a catalogue of meters usable for smart metering, which is based on available information from particular producers. The final part of this thesis gives information about a pilot project of ČEZ company and about another possible functions of smart meters which could be of use in the future.

Nonstandard test of energy meters
Jurka, Tomáš ; Drápela, Jiří (referee) ; Wasserbauer, Vojtěch (advisor)
This thesis covers a brief overview of the development of the energy meter technology as well as a division of the modern energy meters and a description of the functions of electromechanical and static energy meters. The thesis also contains a list and a simple description of the type tests in compliance with the applicable standards relevant to the energy meters. Furthermore, the thesis describes the impact of differential disturbances in the band from 2 kHz to 250 kHz. The paper also defines the IEC-61000-4-19 standard and describes the testing system for measuring the impact of differential disturbances in the band from 2 kHz to 150 kHz. The thesis includes a description of the data acquisition software that was created in the Matlab program. The final part of the paper focuses on a description of the results of parametric tests and the proposal for their adjustments.
