IT7900P High Performance Regenerative Grid Simulator

IT7900P

Adopting advanced SiC technology, the IT7900P series high-performance Regenerative grid simulator provides an all-in-one test solution that can be used not only as a grid simulator and four-quadrant power amplifier, but also as a four-quadrant  regenerative AC/DC electronic load. The full four-quadrant operation, regenerative ability can feedback power to the grid, meet the needs of environmental protection, but also save a lot of electricity and heat dissipation costs. Compact, modular and efficient structure design allows the IT7900P up to 15kVA in 3U single unit, and its power can be extended to 960kVA after master-slave parallel connection. Colorful touch screen with intuitive GUI allows IT7900P to directly define different waveforms. The rich operation modes can meet the test requirement of single-phase, three-phase, reverse-phase and multi-channel. It provides high flexibility for testing and can be widely used in many fields such as PV, ESS and EV.

Functions and Advantages

 

All in one unit

IT7900P series integrates 3 products, a grid simulator(IT7900), an AC/DC power supply (IT7800) and a regenerative AC/DC load (IT8200).

 

4-Quadrant output

IT7900P series is not only a full four-quadrant power grid simulator, but also a full four-quadrant AC/DC electronic load. It can operate in all four quadrants. The efficient energy regeneration function makes it good for testing the frequency change of grid-connected PV inverters, voltage transients and anti-islanding protection.

High power regeneration efficiency

Whether it is used as a grid simulator or a load, in AC or DC mode, the IT7900P is high efficiently power regenerative. The energy generated by the DUT can be fed back to the local grid instead of dissipating in the form of heat, which is good for energy-saving and environment protection.

 

Professional Anti-islanding Test Mode

To meet the certification test of anti-islanding effect for grid-tied products, the IT7900P 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 RLC load and power meter.

 

Data acquisition and simulation

IT7900P series integrates an advanced data acquisition system based on digital signal processor, and provides measurement and waveform analysis functions of a digital oscilloscope, a power meter and a digital multimeter. Its current measurement accuracy is as high as 0.1%+0.2%FS, and the voltage measurement accuracy is as high as 0.1%+0.1%FS. 6 oscilloscope curves can be displayed at the same time, which not only saves the cost, but also saves the time for wiring connection. The trigger configuration of IT7900P can synchronously capture the voltage waveform of the DUT, and realize the functions of data acquisition and simulation. The user can import the collected abnormal voltage data of the power grid into the IT7900P to reproduce the power grid status, set the repetition times, offset and other parameters of the waveform.

 

Simulate power grid and low voltage ride through (LVRT) testing

Low voltage ride-through refers to the ability of the power generation system to continue to operate without disconnecting from the grid within a certain range of voltage drop when the grid fault or disturbance causes a voltage drop, and even provides a reactive power to help the system recover the voltage. You can edit the test parameters under LVRT condition. With the fast response, it can fully meet the test requirements of LVRT. At the same time, the IT7900P series has the function of arbitrary waveform. With the LIST function, it can edit and simulate various grid disturbance waveforms through the panel or software, such as instantaneous power failure, surge and voltage rise and fall.
