Real-time Demonstrations

PMU Pre-compliance test-suite:

A test-infrastructure is proposed that uses low-voltage signals to validate the functionalities of a PMU under test. The test infrastructure is based on National Instruments’ cRIO hardware.
The test-hardware can be easily controlled by a user from the GUI-based software designed in LabVIEW.
A prototype PMU is put under the tests (using our test-suite) and its performance is analyzed and compared with the others available in literature.
Possible adjustments of the test-suit on hardware and software ends are proposed.

Networking experiments on Khorjin based synchrophasor synchornization gateway:

cRIO based HW-SW setup to parse, synchronize, timestamp, and display multiple C37.118 streams.
The PMU streams are corrupted with external networking hardware.
The network is tampered with delay, data-drip and jitter to test its resillience.
Demonstrated in: NASPI Meeting 2019

GFOV investigation in RT for DERs:

Investigates the presence and effect of Ground Fault Overvoltage (GFOV) phenomenon in Grid-Connected PV inverters.
Examines whether conventional neutral grounding, which eliminates this GFOV issue in synchronous generators- are necessary for inverter-based systems.
Tests the effectiveness of SPOV mechanism against GFOV and LROV.

SSGC based resillient networked-control for BESS:

Implementation of a synchrophasor synchronization gateway and control (SSGC) hardware based on cRIO and Khorjin library.
SSGC houses the secondary control functionalities for BESS which runs in a microgrid simulated in Typhoon HIL 604.
The network for the PMU placed at BESS is attacked with external hardware.
Network delay, data-drops and jitters were injected in the network to test the robustness of the control-network.
An LPF was incorporated to get rid of all high frequency components of the control signal, to protect the Li-ion battery.
