Grid Simulation & Microgrid
A Fully Functional Grid Simulator
The BRITE Energy Labs have a complete and functioning 25kW microgrid that includes a grid tied inverter, battery storage, PV interface, AC load bank, and monitoring instruments. All components are connected using a plug-and-play architecture that allows your microgrid component (inverter, circuit breaker, controller,etc.) to be quickly connected in an appropriate place in the circuit. This allows your device to be evaluated in a real-world microgrid setting.
Our NHR 9410 Regenerative Grid Simulator is a unique four-quadrant bi-directional AC/DC source that simulates the utility voltage and regenerates power sourced by grid-tied inverters. The 9410 is used as a grid simulator, or emulator for testing PV inverters and other grid-tied products for compliance to IEEE 1547, UL 1741, and global industry standards. A wide-range of AC conditions can be emulated including phase imbalance (in voltage and/or phase angle relationship), voltage sag, frequency changes and harmonic injection.
The 9410 is flexible in both output form and power level. Output can be AC or DC and the AC can be single, split or 3-phase. Frequency is programmable between 30 and 100 Hz, power levels up to 25kW. It is able to replicate power line disturbances through a combination of user-definable waveforms and Macros. User-defined waveforms permit generation of non-sinusoidal voltages including asymmetrical inflections, transient anomalies, voltage harmonics, or any other irregularity which can be drawn as a single-cycle. The grid simulator can emulate sub-cycle transients, phase jumps and multi-cycle line conditions as required.
