Accurate Grid Simulation for Grid Compliance Testing
The GSZ Regenerative Grid Simulator supports both low and high voltage ranges for AC or DC. Test accurately with seamless transition of voltage ranges. The constant power voltage range for both higher current at lower voltage and higher voltages at lower currents eliminates the need to switch between voltage ranges. This prevents potential disruptions in output power.
- The Industry’s Widest Operating Envelope
- More Current at Lower Voltage
- AC / DC Dual Voltage Ranges
- Seamless Transition of Power
For real-time Power Hardware in the Loop (HIL)grid simulation applications, the GSZ offers a high speed set of analog inputs and outputs with fast output response. This analog interface provides high speed input for controlling frequency, voltage or current and waveshape. Voltage and Current output capture signals are returned to the Real Time Simulation System.
- Amplifier for PHIL applications
- Latency of less than 50µs
- High Speed Analog Inputs
The Regenerative Grid Simulator – GSZ Series has a built-in waveform digitizer and scope with fast transient capabilities at 200µs time resolution supporting LIST, PULSE and STEP modes. Waveform generation includes ten Standard, Sine, Square, Triangle, Clipped and Harmonics AND inter-harmonics generation.
- AC, DC configurations
- Simultaneously test AC and DC, Source or Load on separate phases
- Full galvanic isolation from facility AC input to output and between output phases/channels also protects the user and the UUT.
Simultaneous AC and DC operation of modes per phase(or channel), and the automatic switching of output modes provides test engineers with a unique capability and the highest degree of flexibility. AC, DC output configurations are available in single, split, three phase and multi-channels with optional isolated neutrals in AC and DC.
- AC, DC multi-channel configurations
- Simultaneously test AC and DC, Source or Load on separate phases
- Full galvanic isolation from facility AC input to output and between output phases/channels also protects the user and the UUT.
