Understanding TCSC Control Strategies
A TCSC regulates transmission line reactance by adjusting thyristor switching angles. The effectiveness of this process depends on the control mechanism used to manage power flow dynamically.
1. Open-Loop Control (Fixed Compensation Method)
✔ Uses predefined compensation settings to regulate impedance.
✔ Suitable for steady-state power systems but lacks real-time adaptability.
2. Closed-Loop Control (Dynamic Adjustment Method)
✔ Continuously monitors system voltage, frequency, and load variations.
✔ Uses feedback mechanisms to optimize impedance dynamically.
✔ Prevents power system oscillations, enhancing grid reliability.
3. Adaptive Control with AI & Machine Learning
✔ Uses predictive analytics to anticipate power fluctuations.
✔ Adjusts impedance based on historical data and real-time conditions.
✔ Enhances fault tolerance, response time, and system efficiency.
