NH Research 9510-200 Regenerative Grid Simulator

Built to meet international regulatory standards, the NH Research 9510-200 Regenerative Grid Simulator is a high-performance tool for evaluating and validating high-power grid-tied solutions. With configurable voltage modes such as constant voltage (CV), constant current (CC), constant power (CP), and Power Hardware in the Loop (PHIL), it provides four-quadrant operation. The simulator has versatile output configurations, allowing 3-phase AC, 1-phase AC, or DC outputs, with a maximum power rating of 200kW/472kVA. It has current ranges of up to 1350A in 1-phase mode and 450A per phase. The simulator provides accurate simulations with a voltage precision of ±0.1% F.S. and operates throughout frequencies from 30Hz to 120Hz with exact voltage ranges from 10 to 350VRMS L-N. When in DC mode, the NHR 9510-200 can operate at constant voltage, current, and power, which makes it appropriate for DC system testing. It is perfect for high-power testing applications because of its 200kW maximum power and 1200A maximum current range in single-channel mode.

The primary objective of the NHR 9510-200 is to directly simulate power line disturbances, such as low-voltage ride-through (LVRT) events, in order to make testing for grid-tied systems easier. To provide test sequences for sub-cycle and multi-cycle disturbances, users can design unique waveforms and macros, giving them exact control over the test parameters. The sophisticated digital measuring system offers automatic event tracking and reporting on critical cycle points, which streamlines regulatory testing for UL1741 and IEEE1547.1.

For PHIL applications, where real-time simulation systems must communicate with hardware that is being tested, the NHR 9510-200 is perfect because it can be externally controlled via low-latency, per-phase analog inputs. Superior research applications can benefit from the smooth integration of real-time systems made possible by the integrated power amplifier mode, which also improves PHIL testing capabilities.
