Abstract:

Power transformers are one of the most essential components of energy transmission and distribution systems. With the advances in power electronics and microprocessor technology, electronic power transformers (EGTs) are being developed and designed, which are expected to replace classic power transformers in the near future. EGTs have less volume and weight than classic power transformers with appropriate designs. In addition, with the appropriate EGT structure, the reactive power combination, harmonic combination, voltage collapse / elevation combination can be achieved. In this study, the experimental installation of a three-phase EGT consisting of entrance, isolation and exit parts was carried out. This EGT structure and the brokers in the network can compare thanks to the DA-bars located in the entrance. Usually, in the entrance part of the EGT, the DGM-based confirmations are widely used. In DGM-based verificators, PI or PID controls are preferred due to their simple structure. However, these controllers do not show satisfactory performance in nonlinear systems because they have fixed earnings parameters. Therefore, in this study, a Type-2 nervous discharge controller (T2SBD) was recommended for the control of the DA-bara and dq-exen flows in the entrance section. Furthermore, the recommended control structure is aimed at improving the performance of EGT against detoxifers. The control algorithms developed for EGT’s input and output parts are provided with the dSPACE DS1104 control card. Real-time working conditions have been prepared and experimental results have been obtained to show the voltage collapse, rise, harmonious and reactive power combination performance of the EGT controlled by T2SBD.
