Series compensation on EHV lines is resorted to
- A. Improve the stability
- B. Reduce the fault level
- C. Improve the voltage profile
- D. As a substitute for synchronous phase modifier
Answer: A. Improve the stability
Explanation: Series capacitive compensation cancels part of line inductive reactance X, increasing power transfer capability Pmax = (V1·V2)/Xnet and significantly improving transient and steady-state stability limits.
