Load regulation formula.
To define Line regulation in percentage, it is the ratio of change in output voltage to change in input voltage. Line voltage can also explained in percentage per volt (%/V) If line regulation in percentage per volt is 0.10%/V means that the output voltage changes 0.10 percent when the input voltage increases. or decreases by one volt.
It can be seen that the load trough time is between 0:30 and 7:00, peak load occurs at 10:00–22:00 and 20:00–21:30, the daily load rate is only 87%, and these data shows the generator utilisation is low; however, we must take the peak capacity of the power consumption as the standard in the construction of power transmission and distribution.1.9/8/2005 Line Regulation.doc 1/4 Jim Stiles The Univ. of Kansas Dept. of EECS Line Regulation Since the Zener diode in a shunt regulator has some small (but non-zero) dynamic resistance rZ, we find that the load voltage VO will have a small dependence on source voltage VS.
