How to use taskbar ?
When Excel starts, InorXL will add its toolbar to the main ribbon and create taskbar to the right edge of Excel window. Taskbar helps you to inspect calculation process and to check possible error and warning messages. Taskbar is dockable window. It may be detached from main workspace and behave like independent window. You can close taskbar, but on the load flow command it will appear again. There are two areas in the taskbar. The first area is calculation results list, second is a log. Areas are di- vided by splitter. You can move splitter to control each area size. If taskbar width is greater than height, areas will be oriented horizontally, otherwise – vertically. At each load flow areas are cleared. When iterative calculations are performed, some technical parameters appeared to the calcula- tion result area. These parameters may be useful to identify and get rid of convergence problems. N Iteration number P Maximum error on active power in MW. This is infinite norm of P vector Bus Bus with maximum active power error Q Maximum error on reactive power in MVar Bus Bus with maximum reactive power error MinV Minimum voltage magnitude in KV Bus Bus with minimum voltage magnitude MaxV Maximum voltage magnitude in KV Bus Bus with maximum voltage magnitude ‖𝐈𝐦𝐛‖ Euclidean norm of composite PQ error vector Errors can help to estimate iteration progress. Sequential decrease of errors shows good con- vergence. Errors may have peaks, related to PV/PQ bus type switching. Voltage magnitudes determine solution quality. When voltage magnitude drops below 0.5 of Unom or raises greater than 2 of Unom, calculation interrupts with error. Calculation module tries to keep voltage magnitudes in acceptable ranges by ordered PV/PQ bus switching. Startup method does not use ‖Imb‖ parameter, thus you may see “N/A” in this column for startup iterations. Startup method iterations are shown in gray text and Newton method are in black text. Log area shows basically messages, warnings and errors. You can click message, and in most sit- uations InorXL will show worksheet and object on which message was generated. Download 1.11 Mb.
