DC Load Flow and Short-Circuit modules provide analysis capabilities
for engineers to design and maintain DC power systems. DC Load Flow calculates bus voltage profiles and branch
power flows for user-specified conditions. It compares the calculated operating values against capabilities
such as bus voltage limits, cable ampacities, and source output limits. DC Short-Circuit evaluates system conditions
under a fault and assesses protective device ratings. |
