Input Waveform
Output To
Customer
A voltage sag/swell in the utility waveform is seen by the customer without a Custom Power Device in the substationSags and swells can have severe affects on the Customer LoadImplementing the Customer Power Devices into the substations will correct the waveform
DynamicVoltage Restorer
Power electronic converter injects appropriate voltageActs as a buffer, used for injecting or absorbingCan Compensate a 50% three phase voltage dip for up to 50 cyclesCover a power range from 3MVA up to 50 MVA

Modeling a Substation in ATPDraw
4 Substations To Be Modeled
1 Bus Fed - 2 Transformer 1 Best Feed - 2 Transformer 1 Typical Line Fed - 2 Transformer 1 Typical Line Fed - 2 Transformers Operating in Parallel
Problems That Arose
ATPDraw Does Not Contain Circuit Breaker Models ATPDraw Does Not Contain Automatic Throwover Switches ATPDraw Does Not Contain Custom Power Devices

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 ATPs defined structure by compiling a basic situation for the Custom Power Device.
SPRING PLANS
Complete, integrate, and test ATP modelsEvaluate with different load configurationsMake recommendations based on simulations and results attainedWrite final report Graduate
