⚡️ Series Compensation in Power Systems

Series compensators are used in transmission lines to reduce line reactance and improve power transfer capability.

Formula:
Xeffective = XL − XC

🔹 Why used?
✅ Increase power transfer
✅ Improve voltage regulation
✅ Enhance system stability
✅ Reduce transmission losses

🔹 Where used?
• Long transmission lines
• 220kV / 400kV / 765kV systems
• Heavy load power corridors

🔹 Types:
• FSC (Fixed Series Capacitor)
• TCSC (Thyristor Controlled Series Capacitor)

Lower reactance = Better power flow ⚡️
