Small Network Model with Multiple Test Sequencing

A large number of tests can be pre-programmed and run several times using Python scripts. The Automated Fault Sequencer synchronizes on the positive zero crossing of Phase-A voltage as measured from BUS1 (generator side). After zero crossing, the fault is started at t = fault_starttimes, a parameter set via the Python script. The fault lasts for t = fault_duration, which is also a variable set via Python script. Then, the waveforms are acquired from synchronization to time t = acquisition_time. Waveform data is then saved in MATLAB .MAT format for future analysis. This can then be used to conduct statistical studies such as Monte Carlo-style power system studies.

 

A custom Interface was built using the RT-LAB TestDrive GUI. TestDrive has an interface based on LabVIEW software from National Instruments and can also be scripted using Python. TestDrive uses the LabVIEW runtime engine, enables users to build on-the-fly LabVIEW displays and control panels by virtually wiring real-time simulation signals to graphical displays. TestDrive also has built-in display triggering capability that enables the display of complex waveforms in real-time and the synchronization of those waveforms to specific events like a fault or control signal step.
