Testování vlastností elektroměrů a wattrouterů

Abstract

This thesis examines the impact of abnormal conditions in the power grid to influence the measurement of electricity meters. This is essentially a high harmonic content in the current and voltage waveform and rapid changes between the electricity supply and electricity consumption to the power grid. These rapid changes cause a device called wattrouters. They serve to regulate the surplus energy in homes with own photovoltaic power plant. This thesis also deals with testing a particular type wattrouter Greenbono and its impact on the power grid in terms of flicker.
