Calculation Process for Configuring AHF Modules

To accurately configure AHF modules, we need to consider the following parameters:

  • Transformer Capacity: 2000 kVA
  • System Voltage: 400 V
  • Total Current: 75% of rated current
  • Current THDi: 35%
  • Target THDi: 5%
  • Redundancy Factor: 30%

Step-by-Step Calculation

Determine the Rated Current of the Transformer:The rated current Irated​ of the transformer is calculated using the formula:

 

Conclusion

By following the detailed calculation process outlined above, we determined that 4pcs 200A AHF modules are needed to achieve the desired reduction in THD, considering a 30% redundancy factor. This accurate calculation ensures the optimal configuration of AHF modules, enhancing power quality and system reliability.
