1.1 Brief Introduction
ITECH IT7900 series represents a new generation of programmable, full power
source and sink 4-Quadrant grid simulators and also can perform as a 4-
Quadrant power amplifier, providing the flexibility to test widest range of grid-tied
devices, including PCS, energy storage systems, micro grids, BOBC (V2X) and
power-related hardware in the loop emulation (PHiL).
The IT7900 series is equipped with a professional anti-islanding test mode,
allowing the user to set R, L, C and active and reactive power parameters to
simulate non-linear loads on the grid and achieve anti- islanding testing
requirement. The IT7900 series supports energy recovery function that provides
100% current absorption and feeds back into local grid through the device,
saving electricity bills and heat dissipation costs.
ITECH IT7900 Regenerative Grid Simulator adopts high power density design
of 15kVA in 3U enclosure and provides wide voltage ranges up to 350V L-N and
500VL-N. Easily expandable by Master-slave parallel configuration for higher
power up to 960kVA. Comprehensive options of operating modes can meet
users' requirements for single-phase, three-phase, reversed-phase and multi-
channel testing requirements. Extended AC voltage range to 700V L-N enabled
by reversed mode. The powerful arbitrary waveform editing function can
simulate a variety of grid disturbance waveforms, which is an ideal solution for
testing and R&D laboratories.
