Load Flow Display Options

Output Reports

• Load flow calculation results are reported both on the one-line diagram and in the Crystal Reports format.

• The Report Manager can be accessed from the Load Flow toolbar.

• The Report Manager allows selecting formats available for different portions of the report and view it via Crystal Reports.

Results – Display options

• The way which the results appear on the O.L.D. can be modified using Display options.

• For the Short Circuit Analysis mode there are two possible display options based on the method followed for the analysis –IEC or ANSI.

Motor Starting Time-Slider

• Once a motor starting study is completed, the Motor Starting Time-Slider, will appear next to the Configuration & Mode Toolbar.

• The slider ranges from zero to the total simulation time.

• Initially, the reference pointer is at the far left, corresponding to t = 0 seconds.

Harmonic Load Flow Slider

This slider has three

sections. They are:

• Total

• 1 (fundamental

frequency)

• h (a harmonic order

from 2 to 73).

Harmonic Frequency Scan Slider

Harmonic Frequency Scan

Slider displays the magnitude

and phase angle of the bus

driving point impedance for

the selected frequency. Only

those buses, which are

selected in the Harmonic

Study Case Editor for

plotting, are available to

display.
