INTEPRO Three Phase Utility Grid Simulator Features Energy-Saving Regenerative Power Source

Tustin, CA — Intepro Systems, a market leader in power component and power system automated test equipment (ATE), announces the introduction of the PAS-F Series of programmable three-phase utility grid simulators. The PAS-F combines utility grid simulation and regenerative bi-directional AC source that is capable of both sourcing and sinking the full current load from the device under test (DUT). With power levels ranging from 45kVA to 1.6MVA, the series is capable of testing the largest of dispersed energy inverters.

When testing dispersed energy products such as PV inverters, energy storage systems and wind turbines, the traditional test set up requires a load bank in parallel with the DUT and AC source. The PAS-F does not require the parallel load. Instead full DUT current is sunk into the AC source and 92% of the power is regenerated back to the utility grid, saving energy and reducing system cooling requirements.

The PAS-F offers fully adjustable output voltages (up to 305 V line-to-neutral, 528 V line-to-line) and frequency (40-70 Hz). It features embedded low-voltage-ride-through (LVRT) test windows to allow for simple programming of compliance routines including the new 10% LVRT requirements. The DSP based controller allows for independent phase angle, voltage and phase imbalance control to meet requirements such as IEEE1547 where multi-phase inverters must be tested on an individual basis and all phases simultaneously. The PAS-F can also be used as a reference AC source for use in UL1741, IEEE1547, BDEW (German) and CEI0-16 (China) compliance testing.
