The active harmonic compensation AHC proposed in this article can be used for the industrial networks and can be uses successfully with the non-linear loads. To improve the supply quality of other loads supplied from the same mains, this can be used and is suitable for the consumers with rapid fluctuations of reactive and active power consumption.
advantages of AHC
The design is independent of line impedance and hence the device can be sized to meet the needs of the application
both the harmonic and reactive currents are controlled actively.
The high cost is the main limiting factor behind the AHCs widespread usage. However some advancements are favouring the AHC such as the mass produced hardware in the active filter which cam be used in the device ans can considerably reduce the cost.
Control system:
The control scheme of the system is based on the cascade control architecture. There is a current control in the inner loop without mains sensors voltage. the output voltage of the voltage source inverters is produced by the current sensors for each of the sampling period.
