21.9. Performing DC power flow calculations

 
To perform the DC power flow calculations, the user should use the “Calculate” drop down menu and choose the option “DC power flow”. The calculation results (voltages, current, voltage drops) will be displayed near the corresponding scheme elements.
 
 
           In this particular example, the source middle point is grounded, therefore, both source poles have 5,965V and -5,965, as the middle point is 0V.
           Here are some notable cases that can occur when analyzing the system:
 
The current of a grounded load is very high (10 kA and more)
It means that the system probably has more than 1 grounding element. Check batteries, inverters and loads if they are not grounded.
