The PSL Grid Thumper™ is a tool for testing, measuring and characterizing the stability of the electric grid. By drawing large precise timed pulses of resistive and reactive power, Grid Thumper subtly perturbs local steady-state voltage and phase angles so as to reveal unique stability characteristics of the local grid.
- What is the natural frequency where forced oscillations will have the greatest effect?
- What is the damping coefficient (i.e., how long do oscillations “ring”)?
- How “rigid” is the grid ?
- How do distributed energy resources affect grid stability?
The Grid Thumper is interesting in following area
- to test/simulate grid vulnerabilities to sphisticated cyberattack
- testing of Genset/microgrid
- to emulate the load and understanding of its performance when connected to grid
- Measure actual control loops and damping of population inverters and large electric loads
- Commissioning testing of Substation/PV plant/wind turbine
