A grid simulator is a power supply that imitates an alternating current (AC) power grid for product and standard testing. 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.
How does a Grid Simulator Work?
The device under test (DUT) draws AC power from the grid simulator, which analyzes how the device responds to various grid conditions. A 4-quadrant simulator can sink and source current from the DUT, replicating the voltage and frequency changes that are common with actual grid use.
Many models are now regenerative and conserve energy during all simulations. Instead of dissipating the AC power, a regenerative design 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 provides AC power and emulate a power grid, but there are still some details to consider for the ideal rental.
Grid Characteristics
For the most comprehensive test results, the device must offer a vast range of output ratings and be able to produce various currents, frequencies, voltages, and phases for both AC and DC power. Before renting, confirm it is suitable to the test requirements.
Test Standards
Products like wind turbines, electric vehicles, power inverters, and battery chargers need to meet specific test standards before they are ready for use, and the standard for each type of device differs. Grid simulators not only test for proper use with a power grid but whether a product meets those specific standards. Before renting, ensure the simulator can test for the following standards that may be needed for your DUT:
