ATEC offers regenerative grid simulators at affordable rental rates from trusted manufacturers like NH Research and Chroma to test for industry standards on 4-quadrant power grids.
What is a Regenerative Grid Simulator?
A regenerative grid simulator is a power supply that imitates an Alternating Current (AC) power grid for product and standard testing.
The Device Under Test (DUT) draws AC power from the grid simulator, analyzing how the device responds to various grid conditions. A 4-quadrant grid simulator can sink and source current from the DUT, replicating the voltage and frequency changes that are common with a power grid.
Now regenerative, many models of the test equipment now conserve energy during all simulations. Instead of dissipating the AC power, a regenerative grid simulator returns most or all of the energy to the testing facility. Recycling power allows users to run even more simulations and test products for even more standards.
Choosing the Right Regenerative Grid Simulator
Each model may provide AC power and emulate a power grid, but there are still some details to consider for the ideal grid simulator rental.
For the most comprehensive test results, a grid simulator must offer a vast range of output ratings. The devices can produce various currents, frequencies, voltages, and phases for both AC and DC power. Users should confirm a grid simulation rental has the correct specifications for any testing needs.
Products like wind turbines, electric vehicles, power inverters, and battery chargers need to meet specific test standards before they are ready for use. Grid simulators not only test for proper use with a power grid but whether a product meets those standards. Before renting, ensure the grid simulator can test for the following standards that may be needed for your DUT:
- IEC 61000-4-11
- IEC 61000-3-2
- IEC 61000-3-3
- IEC 61000-3-5
- IEC 61000-3-11
- IEC 61000-3-12
- IEC 62116
- IEEE 1547
- UL 1741
