Troubleshooting

The SINCAL smart load function can fail silently – this is an issue within SINCAL. In this case, there are no unusually error messages or warnings, and results are displayed on the screen, however the smart load function has not stored any results back to the model. If you step through each time slot, you will notice the values do not change.

If this happens, then the study is using the load values in the load elements, plus any load manipulation factors.

You can check the following things if a model is not working:

  • Do not use the Due to Method option. No results will be stored for smart load.
  • In the Calculate->Methods dialog, you need to make sure the Load Assignment and Tap Zone Detection is not selected.
  • Check that the smart load plugin is running. If you can access the task manager, it will be a process with the name zepben_smart_load_server.exe.
  • Check that the Energy Workbench Server is running, and that it has been correctly named in the smart load plugin configurator tool
  • The health of the Energy Workbench Server can most easily checked by accessing one of the trend displays for load data.
  • Check the MasterResource table in the SINCAL MS Access database.
  • Any entries with a ResValue value of 0 will cause the smart load to fail.
  • Any duplicate entries in the ResValue column will cause the smart load to fail.

The following SQL can be used to find duplicates.

select ResValue, count(*) as NumEntries from MasterResource group by ResValue having count(*) > 1;

The load flow engine can also fail with an “Unknown Error”. In this case, try to isolate the part of the network causing the failure by switching different parts of the network around until the smart load works.
