In the main menu bar select “Calculate” and press icon and select “Harmonics”. Keyboard button “F6” can be also used.
Results will appear on the one-line diagram, the user can analyze harmonics spectrum charts by putting the mouse cursor on any of the network elements. Also, observe harmonics results by pressing “Harmonics load flow summary” ( Figure 2.1 Main EA – PSM window ).
Summary table of harmonics load flow results is depicted in Figure 8.5 . Here the user can observe voltage harmonics at each bus and current harmonics at each branch. By pressing icon results will be displayed graphically as depicted in ( Figure 8.6 ).
The red color in the harmonics results data indicated that total harmonics distortion value is over the limit. Yellow color indicates that separate harmonics are exceeding the limit. Harmonic limits are derived from IEEE standard.
Note: Harmonic spectrum charts of each grid element can be observed by hovering the mouse cursor on it and results will be shown directly on the one-line network diagram.
Voltage harmonic limits are provided in EA-PSM according to IEC 61000-3-6. Current harmonic limits are calculated based on Isc/In ratio and are given according to IEEE 519.
EA-PSM allows calculating transformer power losses caused by harmonic load flows. Additional data of low and high winding resistance should be specified in the transformer parameters table. Transformer harmonic losses results are shown in the graph below. Data like active power losses in the transformer windings and eddy current losses are automatically calculated. Also, transformer temperature increase of oil and windings due to these losses are calculated.
