ITECH IT7900 Regenerative Grid Simulator
The IT7900 series is a programmable, four-quadrant grid simulator. It can also operate as a four-quadrant power amplifier which can be used to test various grid-connected equipment, such as PCS, energy storage system, microgrid, BOBC (V2X), PHiL, etc. With the islanding mode (RLC settable), a single IT7900 unit can realize the anti-islanding protection test. The IT7900 series offers up to 15 kVA in 3U size, with parallel connection power can be extended to max. 960 kVA.
- Up to 15 kVA in 3U rack space, 16...150 Hz.
- Regenerative grid simulator and full 4-quadrant AC/DC power sources.
- Power amplifier function for PHiL applications.
- Professional anti-islanding test mode, can set and simulate the RLC (resistive-inductive-capacitive), active and reactive power circuit for anti-islanding detection.
- Three working modes CV/current limit/power limit.
- AC, DC, AC+DC or DC+AC output capability.
- Comprehensive working modes selectable: Single-phase, three-phase, reversed phase and multi-channel (2,5 kVA model only single-phase).
- Programmable output impedance, allows simulation of real-world utility grid impedance (on request).
- Compliance tests incl. LVRT/phase jump/frequency variation/harmonic injection.
- Supported regulatory testing include IEC61000-4-11/4-13/4-14/4-28 etc.
- Wide voltage ranges: 350 V L-N and 500 V L-N (on request).
- Master-slave parallel with current sharing technology, up to 960 kVA.
- Intuitive touch screen; built-in single/3-phase AC power meter; scope function.
- Fast response time and high accuracy 0.1% + 0.2%FS.
- Waveforms library : Sine, square, triangle, clipped sine, trapezoidal, self-defined.
- Harmonics and interharmonics waveform synthesizer.
- Power line disturbance simulation testing by LIST programming/sweep/Surge and Sag functions.
- The harmonic measurement function can measure 50th order harmonics of voltage and current (voltage and current harmonic analysis, voltage harmonic simulation).
- Output 0...360° start/stop phase angle can be set.
- Front panel USB port for data and waveform import and export.
- Provides various trigger input/output signals. When amplitude/frequency changes, trigger signals can be generated to synchronously capture the current waveform of DUTs.
- Relay CTRL function, to cut off the connection between instrument and DUT.
- Frequency lock and phase lock function, tracking the external signal frequency and phase, to achieve 6-phase and 12-phase power output.
- Built-in USB, CAN, Ethernet/LAN, digital-I/O interface, optional GPIB, analog, and RS232.
