NHR 9510 HIGH-POWER SYSTEM FOR GRID SIMULATION03

The Industry Leading Solution for Testing and Verificationof High Power Grid-tied Applications
The 9510 Regenerative Grid Simulator is the industry leading solution for testing and verification of high power grid-tied applications incompliance with regulatory testing standards, worldwide. The 9510 has a built-in power amplifier mode for Power Hardware in the Loop(PHIL) applications providing further testing and simulation capability ideal for research labs. Modular and scalable power is available in
100kW modules up to 1.2MW. Programmable frequency is between 30Hz and 120Hz. The output can be AC, DC or AC+DC and the AC canbe single, split or 3-Phase. With this wide range of power, frequency and phase configuration options, the 9510 provides the ultimate flexibility
to test the broadest selection of grid-tied products.

Amplifier Mode for Power Hardware in the Loop (PHIL)
with Low Latency
The 9510 is externally controllable via a low latency, per-phase analog input. This feature amplifies control signals from real-time simulation
systems for power hardware in the loop testing. The dual range output ensures the maximum flexibility and accuracy in PHIL simulations.

Momentary Cessation

The 9510 Grid Simulator is able to directly simulate commonpower line disturbances, such as LVRT test patterns (Fig. 2 and3), through a combination of macros and user-definable wave
shapes. Macros are pre-programmed sequences of settings
which are entered through a user-friendly menu, downloaded tothe grid simulator, and are executed to provide precise control ofthe output(s). This method is used to generate LVRT test patterns,
sub-cycle, and multi-cycle changes to the output covering nearly
every need.

Waveforms
User-definable wave shapes extend this capability by permitting the generation of outputs including transient anomalies, voltage harmonics,
or any other irregularity which can be drawn as a single cycle (Fig. 4 - 6). These wave shapes can be played continuously or switched inthrough the macro programming interface.

The Power of Choice:Flexible Control Options
There are multiple ways to control the 9510 High Voltage
Grid Simulator.


Fully programmable using NI standard tools such as LabVIEWand VeriStand. These include SCPI, OS-independent LabVIEW
VIs for Windows applications.
An integrated Touch-Panel provides a simple manual control
interface and allows basic tests to be run within minutes ofpowering up the tester.
For more complex test programs, a remote soft-panel interface
on the user’s PC or laptop provides additional control features
such as wave-shape editors, waveform captures and test
program step controls using Macros.

Protection and Safety
The 9510 has built-in safety features to prevent serious failures and protect the operator, UUT, and the facility. Internal hardware contactors
isolate the power module from the device under test and the facility power. Protection features cover grid-side (line in), internal (9510), output(UUT) failures, and detection of unintentional Islanding conditions. Interlock and eStop are provided for rapid shutdown.
