Vehicle Electrical Safety Testing Equipment Feedback Power Grid Simulator RS485

Electric Vehicle Feedback Power Grid Simulator

SNEBP series regenerative grid simulators are used in new energy industries such as charging piles, energy storage inverters, photovoltaic inverters, wind energy converters and other products for grid connection performance testing. The input end of the product adopts digital PWM rectification technology, and the output end adopts independent digital high-frequency inverter technology. It has full energy feedback to the grid, high input power factor, low grid pollution, high output waveform quality, fast dynamic response, and three-phase independent Adjustment and other advantages.

Main Features

1. With multiple output modes, powerful functions:

     (1)Three-phase standard mode: standard three-phase voltage output;

     (2)Three-phase unbalanced mode: the three-phase voltage is independently set, and the three-phase phase angle is adjustable from 0.0° to 359.9°;

     (3)Parallel single-phase mode: three-phase parallel connection into high-power single-phase output;

2. The three-phase mode output adopts three-phase decoupling design, with comprehensive power grid abnormal simulation functions: grid distortion, grid fluctuation, three-phase unbalance, etc., and 2-40 harmonics can be superimposed in the harmonic mode;

3. Equipped with four-quadrant operation function, realizing 100% energy feedback to the grid;

4. It meets the low (zero) voltage ride through test requirements specified by the NB/T32004-2013 standard, and the low (zero) voltage ride through performance is reliable, and it will not resonate with the load at low voltage.
