NHR Presents at Intersolar 2020: Managing the Impacts of Electrification on the Grid

Power Lines Field

NH Research Inc., (NHR) a leading provider of power testing instruments and systems for the automotive, renewable energy, energy storage, and critical-power markets, will be presenting at Intersolar North America 2020.

Martin Weiss, Product Director at NH Research, will present in a talk entitled, “Bi-directional Test Solutions to Manage the Impacts of Electrification on the Grid”. In this session, he’ll share test solutions used by the industry to evaluate electric loading profiles and use cases for EVs, micro-grid, V2G and energy storage applications. This presentation will also review key factors in selecting the right test solution and industry use cases.

NHR Presentation Track: Managing the Electricity Load on the Grid: The Role & Impact of Vehicle Charging
Event: Intersolar North America, 2020
Dates: Feb 4th from 3pm to 4:15pm
Location: San Diego Convention Center, Room 9

Presentation Description:

Bi-directional Test Solutions to Manage the Impacts of Electrification on the Grid

EV DC Fast Charging deployments are accelerating. The ability to simulate these loading profiles is critical for: validating sophisticated load management systems and assessing the impact on the grid. Regenerative bi-directional sources, grid simulators and battery emulators are the engineer’s tool for testing new power management systems, solar (PV), energy storage systems, EVs and DC fast chargers. These bi-directional capabilities are especially ideal for utility companies to test and understand the impacts of e-mobility and grid-tied devices (DG and V2G) on the grid. Simulating the bidirectional power flows to and from the grid substantially speeds up testing time and reduces energy costs.

Key Presentation Takeaways:

• Identify power test approaches for strategic load management & utility grid testing
• Learn about next gen technologies for simulating real-world conditions & load profiles
• Industry use cases

NHR’s flexible test solutions include: 9200 & 9300 bi-directional DC power, 9410 regenerative grid simulator, 9410 AC Source and 9430 4-Quadrant AC loads.

NEW! Model 9420 AC Power Source with HiVAR Technology

NH Research, Inc. is Redefining how AC Power Source Products are Selected

AC Power Source Model 9420 - NH Research, Inc.NH Research, Inc. continues its technology leadership in test & measurement by introducing the 9420 AC Power Source with HiVARTM Technology. The source is compact, modular and field expandable which is ideal for designing into automated test equipment (ATE) systems. An advanced built-in measurement system further simplifies ATE system design by providing the essential functions of a digital multi-meter, current transducer, power analyzer, and oscilloscope. This combination of HiVAR technology, expandable power and built-in measurements make the 9420 an ideal AC source by providing the power and measurement needed for ATE systems as well those commonly needed in general laboratory use.

HiVAR technology extends the usable true power (kW) and eliminates the VA de-rating penalty when reactive power is present. It accomplishes this by providing continuous operation up to the maximum voltage, current and true power (kW). Systems with HiVAR break the VA-only rating tradition in two ways: First, the source is able to transition between high voltage and high current regions along the true power curve without requiring either a range change or requiring the output to be switched off to change ranges. In addition to seamless transitions, continuous true power operation actually extends the usable true power especially when compared with fixed high-voltage / high-current range sources. Second and often overlooked, reactive power (VARS) increases the apparent power (VA) required in test. In the case of VA-only rated systems, this same reactive power negates a portion of a power rating resulting in a lower true power capability thereby requiring a larger source to be initially specified. HiVAR technology extends the apparent power capability, eliminates the VA de-rating penalty and provides a more intuitive selection of AC power sources.

The advanced built-in measurement system is based on a 125kSample/sec digitizer which is able to take advantage of separate voltage and current ranges, further improving measurement accuracy. These range selections are independent allowing any combination of high & low ranges to be selected for voltage and current, occur seamlessly and do not require the output to be turned off. The Model 9420 additionally includes a low current measurement range making it possible to measure standby and low-power operating modes. For more detailed analysis, the high-resolution waveform is available for download and further analysis making any conceivable power measurement possible.
