Abstract
Tema završnog rada je mjerenje parametara kvalitete električne energije i analiza istih prema odredbama Mrežnih pravila. Mjerenje je izvršeno u transformatorskoj stanici 110/35 kV Osijek 1 na sučelju prijenosne i distribucijske mreže. Mjerenje je izvršeno na naponskoj razini od 35kV. Zbog opasnosti od visokog napona mjerenje je izvršeno preko mjernih transformatora u mjernom ormaru. Mjerenje je trajalo tjedan dana odnosno 1008 desetominutnih perioda. Uređaj koji je korišten za mjerenje naziva se PowerExplorer 5 kojega je proizvela tvrtka DRANTZ – BMI. Ima četiri strujne i četiri naponske grane, a upravlja se preko “touch” tehnologije. Postavljen je za rad prema normi EN50160 koja zahtijeva da su postavljeni parametri unutar granica u 95% vremena. Spoj uređaja za mjerenje bio je izveden s tri voda, preko kojih smo motrili napone svake faze zasebno i pomoću troje strujnih kliješta s kojima smo mjerili struje po fazama. Također smo koristili dodatni vod kojim smo mjerili napon uzemljenja. Parametri koji se mjere i prate su: mrežna frekvencija, nazivni napon, promjene napona, dugotrajni i kratkotrajni flikeri, treperenje napona, propadi napona, privremeni mrežni prenaponi, impulsni prenaponi, nesimetrija napona, naponi viših harmonica, naponi međuharmonika i signalni naponi. Granice parametara određene su Mrežnim pravilima elektroenergetskog sustava. Radi toga što su svi parametri zadovoljili normu možemo reći da je kvaliteta električne energije na visokoj razini.
Abstract (english)
The topic of the final paper is the measurement of electricity quality parameters and their analysis according to the provisions of the Network Rules. The measurement was carried out at the 110/35 kV Osijek 1 transformer station at the interface of the transmission and distribution network. The measurement was carried out at a voltage level of 35kV. Due to the danger of high voltage, the measurement was performed via the measuring transformers in the measuring cabinet. The measurement lasted one week or 1008 ten-minute periods. The device used for the measurement is called the PowerExplorer 5 manufactured by DRANTZ - BMI. It has four power and four voltage branches and is controlled via touch technology. It is set up to operate according to EN50160 which requires that the parameters are set within limits 95% of the time. The connection of the measuring device was made with three lines, through which we monitored the voltages of each phase separately and using three current pliers with which we measured the currents by phase. We also used an additional line to measure the ground voltage. The parameters to be measured and monitored are: network frequency, rated voltage, voltage changes, long-term and short-term flicker, voltage flicker, voltage failures, temporary network surges, impulse surges, voltage asymmetry, higher harmonic voltages, interharmonic voltages and signal voltages. The parameter limits are determined by the Network Rules of the Power System. Because all the parameters have met the norm, we can say that the quality of electricity is at a high level.
