Load Flow Analysis

Redirect to

Load flow studies are performed using computer software that simulates actual steady-state power system operating conditions, enabling the evaluation of bus voltage profiles, real and reactive power flow, and losses. Conducting a load flow study using multiple scenarios helps ensure that the power system is adequately designed to satisfy your performance criteria. A properly designed system helps contain initial capital investment and future operating costs.

Load flow studies are commonly used to investigate:

  • Component or circuit loading
  • Bus voltage profiles
  • Real and reactive power flow
  • Power system losses
  • Proper transformer tap settings


  • Decrease unexpected downtime
  • Reduce operating and maintenance costs
  • Get more capacity out of existing assets


A load flow study determines how the electrical system will perform during normal and emergency operating conditions, providing the information needed to:

  • Optimize circuit usage
  • Develop practical voltage profiles
  • Minimize kW and kVar losses
  • Develop equipment specification guidelines
  • Identify transformer tap settings
