A regenerative (active) load system replaces a conventional resistive/reactive load bank used to test equipment such as alternators, motors, transformers, battery chargers, DG sets and rectifiers.
Overview
A regenerative (active) load system replaces a conventional resistive/reactive load bank used to test equipment such as alternators, motors, transformers, battery chargers, DG sets and rectifiers. Instead of dissipating the full test power as heat in resistor or salt-water banks, ACE's IGBT-based system is grid-tied ('grid-locked') and feeds the test power back into the user's own 3-phase grid for reuse — so the source only has to supply the system's loss (efficiency-loss) power rather than the full load power. Buyers choose it to drastically cut the energy wasted during full-load testing, avoid the heat and footprint of dump-load banks, and obtain a controllable, dynamic electronic load with low injected current harmonics.
Specifications
| Topology | IGBT-based active front-end, grid-tied / grid-locked regeneration |
|---|---|
| Function | regenerates test power back into user's 3-phase grid |
| Source draw | only the system's active loss power, not full load power |
| Current harmonics | THDi < 10% |
| Power rating | built to test-target rating (class: tens of kW to MW range) |
| Grid connection | three-phase, 415 V class (50/60 Hz) |
| Load type emulated | active (real) power load, dynamically controllable |
| Control | dynamic / programmable load profile |
| Applicable standards | grid-interface / harmonic limits per IEEE-519 / IEC 61000 class |
Applications
- Full-load testing of alternators and generators
- Motor load / endurance testing
- Testing power transformers, rectifier units and battery chargers
- DG-set load testing without resistive dump load
- Energy-saving replacement for resistive / salt-water load banks
