NH Research launches regenerative grid simulator for testing high-power applications

March 06, 2024

NH Research Inc. (NHR), a provider of power test solutions, has introduced the 9510 Regenerative Grid Simulator. This next-generation AC test solution is designed for testing and verification of high-power grid-tied applications in compliance with regulatory testing standards. The 9510 Regenerative Grid Simulator includes a built-in power amplifier mode for Power Hardware in the Loop (PHIL) applications, offering additional testing and simulation capabilities suitable for research labs. The new 9500 platform complements the NHR 9300 DC test platform, simplifying total electrification testing.

The increasing global focus on sustainability is driving the electrification of vehicles, charging infrastructure, new energy deployments, and grid modernization. The growing demands on the grid and emerging opportunities for distributed energy resources such as solar, wind, and energy storage necessitate modern test solutions that can accurately simulate the grid.

The 9510 Regenerative Grid Simulator offers power levels ranging from 50kW, 75kW, or 100kW modules with a programmable frequency between 30 and 120 Hz. The power is modular and scalable, available in 100kW modules up to 1.2MW. The output can be AC, DC, or AC+DC, and the AC can be single, split, or 3-Phase. The 9510 is a highly modular, flexible, and compact regenerative grid simulator and power amplifier for PHIL applications, with an optional 4-quadrant AC load capability. It is ideal for testing EVs, micro-grid, PV inverters, V2G, and energy storage applications.

Key benefits of the NHR’s 9510 Regenerative Grid Simulator include:

– Scalable power from 100kw modules up to 1.2MW for future increased power demands. The same unit can act as the master or parallel auxiliary unit.– A wide true power operating envelope that covers a broad selection of grid-tied products with a single product. (Voltage: 150V to 350V with full power)– Power Amplifier mode for PHIL with low latency at 50μs for emulation of real-world conditions– High-accuracy current measurement for improved performance and optimized testing.– Built-in galvanic isolation, eliminating the need for an external transformer and simplifying test set-up.– High power density with a small footprint for significant energy, cost, and space savings– Optional 4 Quadrant AC Load capability for flexibility to source and load with a single device
