Documents and Software Solutions:
IT7900 series represents a new generation of programmable, full four-quadrant grid simulators that can also be used as four quadrant power amplifiers for testing all kinds of grid-connected products. Examples include PCS, energy storage systems, micro-grids, BOBC (V2X) and power related hardware loop simulation (PHiL).
With the energy regenerative function, it provides 100% current absorption and feeds back to the grid through the device, saving power and cooling costs. IT7900 series is a high-voltage series with voltage up to 700 VL-N, even up to 1050 VL-N.
The power can be easily extended to 900 kVA by parallel operation. Also, it has touchscreen, concise UI interface, and powerful arbitrary waveform editing function that can simulate a variety of grid disturbance waveforms. It is good choice for test and R&D labs.
Regenerative 4-Quadrant AC Grid Simulator
The IT7900 series are four-quadrant grid simulators with 100% of current source and sink and 88% energy recovery capability. The power generated by the DUT can be fed back to the grid, rather than being dissipated as heat. Suitable for testing grid-connected products that inject energy into the grid, such as frequency changes, voltage transients and anti-island testing of grid-connected photovoltaic inverters.
Touch screen, built-in oscilloscope function
IT7900 series is equipped with innovative touch screen, simple and intuitive UI interface, and the keyboard knob design allows users to perform operations directly and quickly such as mode setting and waveform editing. The built-in digital oscilloscope function collects time-domain signals of voltage and current, phase relationship and performs waveform trigger functions. The oscilloscope sampling rate is up to 10us, and up to 6 oscilloscope curves can be displayed at the same time. Users can perform instantaneous analysis without an oscilloscope and save them in time.
Built-in waveform types
In addition to the basic sine wave, the IT7900 series offers a variety of built-in AC waveforms such as triangle, sawtooth, square, trapezoidal and clipped. Users can recall through the menu and display the selected waveform on the LCD screen. Combined with the device's sequence programming function, the continuous output of different waveforms can be combined to cope with complex power electronic disturbance tests.
