Regenerative Grid Simulator

1. Multi-Phase Output

The system supports single-phase, split-phase, and three-phase output modes. In single-phase mode, it provides higher current output, while split-phase and three-phase modes support lower current output and enable simulations such as three-phase imbalance and phase loss.

In split-phase mode, up to three DUTs can be tested simultaneously, improving equipment utilization while saving space and costs.

Split-Phase Multi-Channel Output 

Three-Phase Output 

2. Multi-Mode Output

The system supports four output modes: AC, DC, AC+DC, and DC+AC. It can provide a pure sine wave in AC mode and DC output in DC mode. AC+DC and DC+AC modes enable DC bias superimposed on AC output or ripple superimposed on DC output, meeting diverse power testing requirements.

• DC Output 
• AC+DC Output 
• DC+AC Output 

3. Harmonic Injection

The system provides realistic grid harmonic simulation. By simply setting the relevant parameters, it can simulate harmonics up to the 50th order, with harmonic content of up to 40%. This supports EMC immunity testing in accordance with standards such as IEC 61000-4-13 and GB/T 17626.13.

4. Programmable Function

With arbitrary waveform generation and LIST/WAVE programming functions, the system can simulate various grid conditions through simple step settings, including voltage dips, voltage ramps, voltage fluctuations, and power frequency variations. This helps verify the DUT's grid adaptability and LVRT/HVRT performance.

• HVRT 
• LIST Step 
• WAVE Ramp 

5. Measurement Function

Based on a high-precision sampling system and advanced DSP technology, the system provides real-time measurement of voltage, current, active/reactive power, and power factor for each phase. It can also display harmonic data up to the 50th order in both numerical and graphical formats, enabling convenient analysis of real-time operating conditions without requiring additional power analysis equipment.
