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

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.
