Abstract

Nowadays as we know most of the loads that we are using will inject harmonics into the system. For removing the harmonics content, in this project we are using two feeders in a distribution system in which a normal transformers are used in both the feeders. In this case we are going to replace one of the feeder transformer by a smart transformer, which consists of three different stages that is rectifier, buck converter and inverter. Rectifier converts ac to dc and buck converter used for stepping down dc and inverter used for dc to ac. So, the operation of the smart transformer is same as normal transformer. But, rectifier consists of IGBT valves, it needs pulses for operation. For generating the pulses we are using ANFIS controller. In that two currents will be taken from both the feeders and it is compared to the reference current and depending on the changes in the current value the pulse will be generated. The current changes means if any harmonics present in the system means it affects the current values so the change value is taken for pulse generation so that the amount of change in current is maintained by the rectifier by taking the pulses given by the ANFIS controller. Thus, the harmonics, unbalance and other things will be mitigated.
