Abstract

Sposób pomiaru mocy energii elektrycznej w sieci rozdzielczej srednich i wysokich napiec charakteryzuje sie tym, ze odczytuje sie napiecie sieci w punkcie ciaglego jego pomiaru i mierzy sie natezenie pradu w co najmniej jednym punkcie pomiarowym zlokalizowanym wzdluz linii zasilajacych od miejsca pomiaru napiecia do okreslonego miejsca pomiaru mocy, po czym wyznacza sie straty napiecia miedzy punktem pomiaru napiecia a okreslonym miejscem pomiaru mocy, przy czym napiecie i natezenie pradu mierzy sie z zachowaniem przesuniec fazowych przez synchronizacje czasu urzadzen pomiarowych, a wartosci natezenia pradu transmituje sie za pomoca interfejsu bezprzewodowego. Uklad pomiaru mocy energii elektrycznej w sieci rozdzielczej srednich i wysokich napiec charakteryzuje sie tym, ze jednostka centralna systemu pomiaru mocy (JC) polaczona jest za pomoca interfejsu z jednostkami lokalnymi (JL1, ..., JLn) ukladów pomiaru natezenia i fazy pradu ( UPP1, ..., UPPn), których mierniki pomiarowe natezenia i fazy pradu. (PP1, ..., PP3) poszczególnych faz (L1, ...,L3) linii zasilajacej polaczone sa z jednostkami lokalnymi (JL1, ..., JLn) za pomoca interfejsu izolowanego galwanicznie, przy czym jednostka centralna systemu pomiaru mocy (JC) i jednostki lokalne (JL1, ..., JLn) ukladów pomiaru natezenia i fazy pradu (UPP1, ..., UPPn) synchronizowane sa zegarami satelitarnymi tych (GPS, GPS1, ..., GPSn) tych jednostek.The method of measuring the power of electricity in a medium and high voltage distribution network is characterized by the fact that the network voltage is read at its continuous measurement point and the current intensity is measured at at least one measuring point located along the power lines from the voltage measurement site to a specific power measurement location , then the voltage losses between the voltage measurement point and a specific power measurement location are determined, where voltage and current are measured with phase shifts by synchronizing the time of the measuring devices and the current values are transmitted via a wireless interface. Electricity power measurement system in medium and high voltage distribution network is characterized by the fact that the central unit of the power measurement system (JC) is connected by means of an interface with local units (JL1, ..., JLn) of current and current phase measurement systems (UPP1 , ..., UPPn), whose meters measure current and phase. (PP1, ..., PP3) of individual phases (L1, ..., L3) of the power line are connected to local units (JL1, ..., JLn) by means of a galvanically isolated interface, with the central unit of the power measurement system ( JC) and local units (JL1, ..., JLn) of current and phase measurement systems (UPP1, ..., UPPn) are synchronized with the satellite clocks of these (GPS, GPS1, ..., GPSn) of these units.
