Plotting of Voltage Contours in P-Q Plane Using Contour Evaluation Program
Keyword(s):
In the current deregulated environment, determining loadability to various security limits is of great importance for the secure operation of a power system. The conventional P-V and Q-V curves are used to determine the voltage stability margin. This paper proposes to find the relationship between P and Q for a constant voltage on a particular bus using a contour evaluation program. The flexibility of this program allows generation of a family of curves which show the amount by which the reactive power loading on a particular bus needs to be modified so as to keep the voltage constant on that bus.
