In the HYPERSIM toolbar, click ScopeView.
For this tutorial, open a prepared template.
Click the folder icon with a T in the upper right corner, and browse to the directory: C:\Users\USERNAME\Documents\HYPERSIM and select the xml template file HVAC_500kV_6Bus.xml.
The acquisition parameters are saved along with the template, so there is no need to apply changes for this tutorial.
However, here are the basics for acquisition parameters:
You can bring up the Acquisition Parameters by pressing the designated button on the toolbar.
| Start Time | Time at which the acquisition starts after pressing the Play button, in seconds. |
|---|---|
| Time Length | Duration of the acquisition, in seconds. |
| Sampling Rate | Number of samples per second used to represent a signal. This number must be an integer multiple of the step size. Otherwise, a linear interpolation of the data points is processed by the acquisition spooler before sending the data to ScopeView (i.e. before the graphs appear). |
Maximum_sampling_rate=1/(Step_size)
| # Acquisition | Number of consecutive acquisitions to process. This mode is used specifically with events programmed to change over multiple acquisitions, such as incremental, Gaussian or uniform Gaussian (in the breaker model). |
|---|---|
| Sync | If checked, as soon as you press Play, the acquisition spooler waits for the voltage (at the bus to which the POW is attached) to cross a specific level (by default, 0) on a specific phase (by default, A), with a specific slope (by default, positive). |
Only then will the acquisition start, as well as the timing for the various events programmed.
| Trigger | If checked, the various events programmed occur. |
|---|---|
| Cont | If checked, acquisitions are performed continuously. |
After setting the appropriate acquisition parameters, start an acquisition. The results should appear in the scope window.
- A fault occurs on Bus WED7 on phase A at 0.028 second. The protection system isolates the line by opening line breakers at 0.1 second.
- The fault is cleared and the line is brought back to service at 0.2 seconds.
- Fault currents as well as bus voltages and breaker currents (for both sides of the line) can be monitored in ScopeView.
