![Page 18: DTS Experiences at Minnesota Power](https://reader036.vdocument.in/reader036/viewer/2022062407/56812ceb550346895d91ae7a/html5/thumbnails/18.jpg)
Problems up front…
• System crashed during Simulation Preparation
• Controlling a non-modeled point crashed DTS
• Reloading snapshots failed
• Could not restart a simulation from a Simulation Data Collection Snapshot
![Page 19: DTS Experiences at Minnesota Power](https://reader036.vdocument.in/reader036/viewer/2022062407/56812ceb550346895d91ae7a/html5/thumbnails/19.jpg)
Tips…• Get DTS Experience before first FAT• DTS is only as good as the Model• Create a DTS Station/Points
– Points can be used for execution of blocks of predefined events immediately through conditional events
– Points can be used as flags and/or pseudo timers with conditional events
![Page 20: DTS Experiences at Minnesota Power](https://reader036.vdocument.in/reader036/viewer/2022062407/56812ceb550346895d91ae7a/html5/thumbnails/20.jpg)
Tips…• Be creative
– Sequential Control– Custom Applications
• Do not reinvent the wheel– Scenarios vs. Power System Functionality
• Script the Scenarios (Library of Scenarios)– Setup, execution and expected results
• Trainer implemented vs scheduled Scenarios
