The steady state stability limit of a power system can be increased by
The steady state stability limit of a power system can be increased by
Show Hint
Lower reactance in transmission lines enhances steady-state stability.
Updated On: May 23, 2025
- Decreasing the excitation of a generator
- Increasing the reactance
- Reducing the reactance
- Using shunt reactors
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The steady state stability limit is directly related to power transfer capability. By reducing the reactance \( X \) of the system, the maximum power transfer increases:
\[
P_{\text{max}} = \frac{EV}{X} \sin\delta
\]
Thus, reducing \( X \) improves the stability margin.
