Elektrik güç sistemlerinde enerjinin üretilmesi, iletimi ve dağıtımı sırasında, akım ve gerilimin, 50 Hz frekansında ve sinüs eğrisine çok benzer bir biçimde olması arzu edilir. Bu koşul, elektrik enerjisinin kalitesini belirleyen ana faktörlerden biridir. Ancak, doğrusal olmayan yüklerin ürettiği harmonikler nedeni ile akım ve gerilim gibi büyüklükler sinüs biçimde olmaktan çıkarlar ve dalga biçimleri oldukça karmaşık hale gelir. Bunun sonucunda, işletme açısından arzu edilmeyen önemli sorunlar ortaya çıkar. Bu problemler, sistemin çalışmasını olumsuz yönde etkileyen ve tüketiciye kaliteli enerji sunulmasını engelleyen problemlerdir. Bu çalışmada, Yalova Üniversitesi Merkez Kampüsünde tüketilen elektrik enerjisinin kalitesi incelenmiştir. Çalışma kapsamında, Merkez kampüsünde farklı noktalardaki güç dağıtım merkezlerine güç kalitesi analizörü bağlanmıştır. Güç kalitesi analizörü ile sisteme ait akım, gerilim, güç ve frekans gibi parametrelerin yanı sıra sistemde meydana gelen güç kalitesi olayları ölçülmüş ve bilgisayar ortamına aktarılarak incelenmiştir. Harmonik ölçümleri sonucunda elde edilen veriler doğrultusunda güç kalitesi problemlerinin sebepleri araştırılarak çözüm önerileri sunulmuştur.
During the production, transmission and distribution of energy in electrical power systems, the current and voltage are desired to be in a very similar manner to the 50 Hz frequency and the sinus curve. This condition is one of the main factors that determine the quality of electricity. However, due to the harmonics produced by nonlinear loads, sizes such as flow and voltage come from being in sinus form and wave forms become quite complex. As a result, significant unwanted problems arise from the business point of view. These problems are problems that negatively affect the system's function and prevent the supply of quality energy to the consumer. In this study, the quality of electricity consumed at the Yalova University Central Campus was studied. In the framework of the study, the power quality analyzer is connected to the power distribution centers at different points in the Central campus. The power quality analyzer and the parameters such as the current, voltage, power and frequency of the system, as well as the power quality events that occur in the system have been measured and studied by transferring to the computer environment. According to the data obtained by harmonic measurements, solutions proposals were presented by investigating the causes of power quality problems.
During the generation, transmission, and distribution of energy in electric power systems, it is desirable that the current and the voltage are in a frequency of 50 Hz and very similar to the sine curve. This condition is one of the main factors determining the quality of electric energy. However, due to the harmonics produced by the nonlinear loads, the magnitudes such as current and voltage are subtracted from the sinusoidal form and the waveforms become more complex. As a result, important problems arise which are not desirable in terms of operation. These problems are problems that adversely affect the operation of the system and prevent the transmission of high quality energy to the consumer. In this study, quality of electrical energy consumed on Yalova University Central Campus was investigated. Within the scope of the study, Power quality analyzers were connected to power distribution centers at different points on the central campus. In addition to the parameters such as current, voltage, power and frequency of the system with the power quality analyzer, power quality events that occurred in the system were measured and analyzed by transferring them to the computer environment. In accordance with the data obtained as a result of harmonic measurements, the reasons for power quality problems were investigated and solution proposals were presented. As well as the parameters such as the current, voltage, power and frequency of the system, power quality events occurring in the system were measured and sent to a computer for analyses. Some solutions were suggested by investigating the causes of power quality disturbances in accordance with the data obtained
