Table 3 Comparison of nonlinear distorted load currents and supply currents
From: A novel ANFIS-controlled customized UPQC device for power quality enhancement
THD (%) | Nonlinear distorted load current (%) | Supply current (%) |
|---|---|---|
Without C-UPQC device | 21.83 | 21.77 |
With traditional PI-IRP-controlled C-UPQC | 21.79 | 3.30 |
With traditional FL-IRP-controlled C-UPQC | 21.77 | 2.38 |
With proposed ANFIS-IRP-controlled C-UPQC | 21.77 | 1.77 |
