Power Flow Analysis

SPGS’s power-flow analysis utilizes a computer model to examine normal steady state and contingency conditions in an electrical system. A power-flow solution provides voltages and equipment loadings under a given set of system conditions. A series of power-flow cases can show the effects of various design alternatives or equipment outages on system operation.

An engineer can use power flow cases to:

Examine benefits of load-tap-changing transformers
Examine benefits of power-factor correction capacitors
Select locations for power-factor correction capacitors
Set taps on fixed-tap transformers
Explore steady state performance of expansion alternatives
Determine ratings for new or upgraded circuits
Determine equipment loading

In addition, a power flow case can provide a snapshot of system voltages during motor starting, impact loading, or other short-term events that affect system voltages.
