Different analytical and numerical methods for the calculation of the leakage reactance of the transformer are presented in this paper. Finite element analysis is used for the simulation of two-dimensional (2-D) and three-dimensional (3-D) finite model of the transformer. Results are also compared with the experimental and analytical methods. The obtained results from finite element analysis show that both 2-D and 3-D energy methods provide higher accuracy as compared to the conventional and inductance method. Energy method is also less time consuming as compared to other methods like flux element and image techniques. The relative error between experimental and finite element energy method is less than 1%. These methods can be helpful for the manufacturers of the transformers for minimizing the design time of the transformer and it can also increase the performance of the transformer.

Due to technological developments, increasing population and rapid industrialization, the need for electric energy is increasing day by day. The increase in electricity demand required more integration of solar power plants (SPP). In addition to meet the electricity demand, it is also important to increase the quality of electricity. At present, SPP provide active power to the network and cause bi-directional energy flow. Since the power factor is set to one, there is no reactive power flow in the network. The effect of changing the power factors of the SPP with the need of the distribution system has been examined in the study. It is aimed to compare the grid voltage profile, the reactive power flow in the network and the technical losses in cases where SPP participates and do not participate in reactive power control. First, the power factors of SPP are set to one as in the real case and the status of the network is evaluated in the analysis results. Analysis was then carried out by changing the power factors according to the reactive power requirement in the network and the capacities of the SPP, and the two cases were compared. As a result of participating in the reactive power control by adjusting the power factors of the SPP, the improvement of the voltage profile, the reactive power flow and the network losses are seen to decrease.

Dağıtım transformatörleri, enerji nakil hatlarının ardından elektrik şebekesinde kayıplara neden olan ikinci büyük bileşen konumundadır. Bu güç kayıpları, transformatörün işletmede kaldığı süre boyunca önemli oranda enerji kaybına ve maliyetlere neden olmaktadır. Transformatörler için boşta çalışma ve yükte çalışma kayıpları, EN 50464-1 standardında primer gerilimlerine ve anma güçlerine bağlı olarak sınıflandırılmıştır. Bu çalışmada enerji dağıtım sistemine dahil edilecek yeni bir dağıtım transformatörünün seçiminde kayıp sınıflarının, transformatörün kullanım süresine bağlı olarak enerji kayıplarına ve toplam kullanım maliyetlerine etkileri karşılaştırılarak yorumlanmaktadır.
