Grid Thumper: a new way to test the stability of microgrids, back-up power systems, and distribution grids

When subjected to stand-alone certifications, individual pieces of grid equipment (generators, inverters, UPS, transfer switches, etc.) almost always operates correctly. When they’re connected together as a system, exactly how their control loops will interact is unknown.

Grid Thumper rigorously tests complete, connected systems, including active distribution grids, detecting harmful instabilities that would otherwise be invisible. It uses patent-pending technology

to briefly connect large, time-synchronized resistive and reactive loads – up to a megawatt, often for a tiny fraction of a second – then ultra-precise PSL PQube 3 and microPMU sensors record the grid’s system response.

Grid operators, data centers, hospitals, military bases, sports and entertainment venues, can all gain peace of mind that their critical power systems will perform as expected when needed most.

 

GRID STABILITY CHARACTERISTICS REVEALED

• What is the damping coefficient (i.e., how long do oscillations “ring”)?

• How far on the grid do oscillations travel?

• How resilient are back-up generators and  UPSs?
