EMP Simulation Example
PowerWorld Simulator version 20 includes the ability to analyze the E3 effects of a high-altitude electromagnetic pulse (HEMP) attack on the power system. Algorithms are based on public Oak Ridge National Laboratory research.
To perform a sample analysis:
- Download this file. Extract the contents and open TX2000.pwb with PowerWorld Simulator (version 20 or higher).
- Open the GIC… dialog from the Add Ons ribbon.
- Select the “Time Varying Series Voltage Inputs” Calculation Mode.
- Check the “Use EMP as Input” box.
- Go to the “Field/Voltage Input” page and then the “EMP” tab.
- Change the parameters if desired, or leave the defaults.
- Click “Calculate EMP Input Time Series”. (A time-series of transmission line GIC DC Input Voltages are inserted.)
- Analyze these in steady-state by changing the Current Time and Calculating GIC Values. (More details on the use of PowerWorld Simulator GIC are available in on-line help and in the GIC training slides.)
- Note the “E3A blast” effect peaks around t=5.4s and the “E3B heave” around t=60s.
- Analyze in Transient Stability:
