Chapter: Power System Operation and Control : Reactive Power -Voltage Control
Dynamic Response of Voltage Regulation Control
The response depends upon the roots of the characteristic eqn. 1 + G(S) = o.
DYNAMIC RESPONSE OF VOLTAGE REGULATION CONTROL
Consider
The response depends upon the roots of the
characteristic eqn. 1 + G(S) = o.
As there are three time constants, we may write
the three roots as S1, S2 and S3. A typical root locus plot is shown in Figure
Root locus
From the plot, it can be observed that at gain
higher than Kc the control loop becomes ln stable.
