NEW & IMPROVED! Regenerative Grid Simulator – Model 9410, from NH Research, Inc.

For the Testing of EV Chargers, V2G, Grid-Tied Inverters, & Critical Power Systems.

Regenerative Grid Simulator Harmonics and Waveform - NH Research, Inc.NH Research, Inc. (NHR) has released new advanced output control features, improved manual control interface, and comprehensive drivers for the popular Model 9410 Regenerative Grid Simulator. These new control features provide intuitive controls for simulating any abnormal AC-grid condition including: voltage harmonics, sags and swells, sub-cycle, full-cycle, and
multi-cycle disturbances. It has never been easier for R&D to validate product designs or for manufacturing teams to ensure functional and regulatory compliance with EN 61000-x, IEEE 1547, UL 1741, CA Rule-21, LVRT, and similar emerging testing standards. Improvements have also been made to permit intuitive access to these new features through the full-featured manual control panels as well as through the fully-documented LabVIEW Compliant & IVI-C / IVI-COM compliant drivers.

The Model 9410 Regenerative Grid Simulator is a full featured, 4-quadrant, regenerative, rack-mountable, 12-kW grid simulator in only 15 ¾” (9U). Standard models include three (3) fully programmable channels allowing for any combination of DC as well as 1Φ, 2Φ, 3Φ AC outputs making it right-sized for testing Level 1 and Level 2 EV Chargers, EVSE systems, as well as V2G. When higher power is required. The modular design permits expansion in 12-kW increments meeting the needs for grid-tied solar inverters, ESS systems, exporting critical power systems (UPS), and similar AC grid-connected devices.

NHR will be exhibiting the Model 9410 Regenerative Grid Simulator along with NHR’s 9200 Series DC Regenerative Test System (which is ideal for testing battery, simulating the DC-links, and emulating batteries) at The Battery Show (Novi, MI) from Sept. 13th-15th, 2016 in booth 1525.

The 3 Key Benefits of Battery Emulation Testing

Battery Emulator Testing vs. Real Battery Testing

Battery Test Systems - NH Research, Inc.There are 3 key benefits to testing battery characteristics by battery emulator or battery simulator testing, rather than using a real battery. Emulating a battery dramatically reduces testing time, provides highly repeatable test results, and creates a safer test environment. This results in preparation time, operator errors, and result variations due to battery temperature or aging, being eliminated.

Battery Emulation Reduces Testing Time

Testing a real battery often requires operator preparation for each step. Batteries must first be charged, or discharged, then allowed to rest, and finally tested. The significant battery preparation time can be avoided by using an emulated battery. Emulation can reduce total test times by more than 70%.

Battery Emulation Provides Repeatable Test Results

Over time, batteries provide inconsistent test results, wear out, and need to be replaced. Battery age, internal temperature, and cycling are all contributing factors to the limited battery life-span. Manual battery operation, including rest time facilitation, can also cause inaccurate test results. Battery emulation provides consistent and repeatable test results, unlike those from real battery testing, during which battery changes and operator errors cause variations in test results.

Battery Emulation Improves Safety

Although batteries are generally safe when operated within normal operating ranges, they are high energy devices that may pose serious risks upon battery or unit under test (UUT) failure. Such risks include exposure to dangerous gases, fires, explosions, or corrosive chemicals. These concerns have led to safety policies stating that tests must be conducted and monitored during working hours. Furthermore, testing extreme cases of over-discharged or over-charged batteries can pose unpredictable risks and safety hazards.

Battery emulation creates a safe testing environment without any of the concerns that arise when real batteries are used. Also, emulation safely verifies UUT behavior when a battery is outside a normal operating condition.

While testing with real batteries is possible, it can seem quite impractical. Using battery emulator or battery simulator testing produces test results faster, provides a consistent test, and can safely test power electronic devices that typically require a real battery. Contact NH Research, Inc. to further discuss how removing real batteries from existing test fixtures will improve both safety and repeatability in testing.

NEW! Regenerative Grid Simulator – Model 9410, from NH Research, Inc.

For the Testing of Grid-Tied Inverters, Vehicle to Grid (V2G), & Other AC Power Products.

regenerative grid simulator model 9410NH Research, Inc. (NHR) has released its new Model 9410 Regenerative Grid Simulator. This test instrument packs a full featured, 4-quadrant, regenerative, rack-mountable, 12-kW grid simulator in only 15 ¾” (9U). Standard models include three (3) fully programmable channels allowing for any combination of DC as well as 1?, 2?, 3? AC outputs. The modular design of this grid simulator permits power to be expanded in 12-kW increments, allowing improved sizing for testing micro-grids, grid-tied solar inverters, on-line critical power systems (UPS), grid-aware chargers, and similar AC grid-connected devices. The 9410 simplifies IEEE 1547, UL 1741, CA Rule-21, and LVRT compliance testing by providing the highest level of integration and programming versatility in the smallest package.

The new Model 9410 Regenerative Grid Simulator adds programmable AC to our regenerative bi-directional product line which includes the popular 9200 Series for DC testing and battery emulation. With the addition of this grid simulator, NHR is now able to offer combinations of AC and DC products specifically designed to simple testing of distributed energy resource (DER) and distributed generation (DG) products by simulating the AC area EPS as well as the DC battery or DC-Link capacitor.
