SISTEM PHOTOVOLTAIC BERBASIS ANFIS UNTUK PERBAIKAN KETIDAKSEIMBANGAN BEBAN PADA SALURAN DISTRIBUSI TIGA FASA

Distribution channels play an important role as a link between the main substation generation center and the load. In three-phase electrical systems, load imbalance problems often occur which have a negative impact on the quality of electricity received by the load. Several factors cause this imbalance, namely the uneven distribution of the load between the R, S, T phases and the operating time of the load for each phase which is not always the same. This research presents system development photovoltaic (PV) as a compensator tool to overcome load imbalances when dynamic loads are active on distribution channels. A PV system with ANFIS combination (Adaptive Neuro Fuzzy Inference System – Proportional Integral) when controlling the inverter, will work actively to compensate for load imbalances by injecting the resulting power into the distribution channel. The simulation results from this research show the success of the PV system in compensating for load imbalances that occur. The unbalance factors obtained before compensation between phases R, S, T are respectively 16.47%, 1.49% and 14.97% and after compensation produce values respectively 0.3%, 0.7% and 0.3% according to load imbalance standards The allowable amount is 3% referring to NEMA-MG 1 rules (The National Electrical Manufacturers Association).
