NH Research 9410-36 Regenerative Grid Simulator

The high-performance AC/DC power source NHR 9410-36 Regenerative Grid Simulator from NH Research is intended for grid-tied device testing, including photovoltaic (PV) inverters. It allows power to flow in both directions and operates in the four quadrants (bi-directional). It supports single, split, or three-phase configurations and has scalable AC and DC output modes with a maximum output of 36kW. With frequency adjustments ranging from 30 to 100 Hz and peak current delivery up to three times its RMS rating, this system is incredibly versatile for testing a wide range of power applications.

With its inbuilt waveform digitization technology and sophisticated instruments for inducing electrical disturbances, the 9410-36 allows for accurate grid condition reproduction. This grid simulator reduces heat loss and increases energy efficiency while it is in regenerative mode, channeling the restored power back to the facility mains. This flexible option is ideal for verifying that grid-connected devices satisfy industry compliance requirements.

Because of its HiVAR design, the NHR 9410-36 has the unique potential to produce more reactive power than conventional systems. Because of this feature, it can continue to operate at maximum power output even in the presence of reactive power or harmonic distortions throughout a wide voltage range. The NHR 9410-36 effectively manages variations in power factor, expanding its testing capability to a wider range of goods than traditional kVA-rated systems, which frequently require oversizing to handle real-world conditions.

The 9410-36 features a waveform editor and macros that let users build unique voltage profiles and anomalies for electrical disturbance modeling. This satisfies both present and future regulatory needs by guaranteeing accurate testing for transient situations such phase shifts, voltage anomalies, and sub-cycle occurrences.
