Abstract
Kod potrošača koji troše velike količine plina, odnosno kod kojih uvjeti u plinomjeru nisu bliski standardnim uvjetima (temperatura plina od 15⁰C i tlak od 101325 Pa), ugrađuju se korektori volumena plina koji svode radni volumen plina u plinomjeru na standardno stanje uz pomoć vrijednosti tlaka, temperature te faktora kompresibilnosti plina. Korektori na lokaciji potrošača su instalirani na razdoblje od 5 godina prilikom kojeg kompresibilnost plina računaju uz pomoć unesenih fiksnih vrijednosti molarnih udjela CO₂ i H₂, gornje ogrjevne vrijednosti i relativne gustoće plina te izmjerenog tlaka i temperature. Zbog svakodnevne varijacije sastava plina, navedene unesene vrijednosti razlikuju se od realnih što uzrokuje pogrešku pri određivanju standardnog volumena, odnosno energije. U ovom radu izračunat je utjecaj varijacije sastava plina na razini distribucijske mreže Gradske plinare Zagreb d.o.o. na pogrešku pri korekciji volumena plina u razdoblju od 2014. godine do listopada 2019. godine.
Abstract (english)
For end users who consume large amounts of natural gas or where the gas meter temperature or pressure conditions are not close to standard conditions (gas temperature of 15⁰C and pressure of 101325 Pa), gas volume correctors which determine gas volume, measured by gas meter if it were operating at standard conditions are installed. The correction factor is calculated using gas temperature, pressure, and compressibility. Gas volume correctors spend a period of 5 years at the users’ location, during which gas compressibility is calculated with the help of manually entered, fixed values of molar proportions of CO₂ and H₂, gross calorific value and relative density of the gas, and measured temperature and pressure. Due to daily variations of gas composition, the mentioned entered values differ from the actual ones, which causes an error in determining standard gas volume and energy. In this thesis, the influence of natural gas composition variation on gas volume correction error is calculated at the level of Gradska plinara Zagreb’s distribution network, for the period from 2014 to October 2019.
