• A voltage sag/swell in the utility waveform is
seen by the customer without a Custom
Power Device in the substation
• Sags and swells can have severe affects on
the Customer Load
• Implementing the Customer Power Devices
into the substations will correct the waveform

Bus
• Power electronic converter
injects appropriate voltage
• Acts as a buffer, used for
injecting or absorbing
• Can Compensate a 50% three
phase voltage dip for up to 50
cycles
• Cover a power range from
3MVA up to 50 MVA

ATP Fortran Modeling Techniques
• Basic Fortran can be used to model
custom power devices in ATP
• Fortran modeling structure includes:
Data Points, Variables, Initializing, and
Executing.
•
Integrating the code into ATP’s defined
structure by compiling a basic situation
for the Custom Power Device.
SPRING PLANS
• Complete, integrate, and test
ATP models
• Evaluate with different load
configurations
• Make recommendations based
on simulations and results
attained
• Write final report
• Graduate
