This block generates a trip signal when there is an over-current event in the DC or AC side of the converter after a specified interval of time.
Mask and Parameters
| Name | Description | Unit |
|---|---|---|
| Sample Time | Computational time step | s |
| AC Current Threshold Value (kA) | Minimum AC current value to activate the trip signal | kA |
| DC Current Threshold Value (kA) | Minimum DC current value to activate the trip signal | kA |
| Action Time Delay (s) | When DC or AC threshold is surpassed, the trip signal is set high after this time | s |
