The IT7900 series is a programmable, four-quadrant grid simulator. It is also a four-quadrant power amplifier, which can be used to test various grid-connected equipment. For example, PCS, energy storage system, microgrid, BOBC (V2X), PHiL, etc. With the islanding mode (RLC settable), a single unit of IT7900 can realize the anti-islanding protection test.

The power density of IT7900 series is very high, 15kVA in 3U. After parallel connection, the power can be extended to 960kVA.

Regenerative 4-Quadrant AC Grid Simulator

The IT7900 series represent the newest generation of programmable, full four-quadrant grid simulators with full 100% of current rating in both source and sink mode, and provides energy recovery capability. The power generated by the DUT during the test can be easily fed back to the AC grid, rather than being dissipated as heat,which protects the environment and lowers the cost of operation. It can be applied to the applications in testing grid-tied products that inject energy into the grid, such as the frequency changes, voltage transients and DC injection of grid-tied/off-grid inverters testing.

Full 4-Quadrant Power Amplifier

The IT7900 series regenerative grid simulator can be used as a power amplifier to complete power hardware in the loop (PHIL) applications for microgrids, energy storage and new energy vehicles. The digital I/O or a standard suite of analog signal can be input via an external analog interface (optional) and then amplified without distortion to a real power waveshape with an external analog response time of less than 200us.

Professional Anti-islanding Test Mode

To meet the certification test of anti-islanding effect for grid-tied products, the IT7900 series provide a professional anit-islanding test mode. Users can adjust RLC parameters or configure the parameters of active power and reactive power to achieve the effect of simulating purely resistive or nonlinear grid loads, and further verify the anti-islanding protection response time of grid-tied DUTs under different equivalent impedances, three-phase load balancing and non-balancing conditions. The solution helps engineers to simplify the test circuit and cost savings of additional equipment such as oscilloscopes and power meters.
