Power oscillation compensation by TCSC
2015 International Conference on Advanced Computing and Communication Systems, 2015A major grid disturbance occurred in the Northern grid of Indian power grid on 30th July 2012, causing a blackout in northern region. The main cause was the malfunctioning of distance relay due to power swing, weak interregional corridor and multiple outage of lines.

Analytical Modeling of TCSC Dynamics
IEEE Transactions on Power Delivery, 2005This paper presents an analytical, linear, state-space model of a thyristor-controlled series capacitor (TCSC). First, a simplified fundamental frequency model of TCSC is proposed and the model results are verified. Using frequency response of the nonlinear TCSC segment, a simplified nonlinear state-space model is derived, where the frequency of the ...

Transient stability control of TCSC
2009 4th IEEE Conference on Industrial Electronics and Applications, 2009This paper studies the strategy of thyristor controlled series compensation (TCSC) to damp power swing in interconnected systems. In interconnected network, TCSC must operate in response to inter-area main swing model, and its capacitive impedance must switch to the largest when the rotated speed deviation between equivalent centers of inertia is ...

Design of TCSC Based Optimal Wide Area Power System Stabilizer for Low-Frequency Oscillation
2021 IEEE 4th International Conference on Computing, Power and Communication Technologies (GUCON), 2021Low-frequency oscillations (LFOs) are the most concerned modes in power systems. A generic power system stabilizer (PSS) can damp the intra-area LFO modes using local measurements.

AbstractThe effect of thyristor-controlled series capacitor (TCSC) and its controller gain on bifurcations of subsynchronous resonance (SSR) in power system are studied. Single machine infinite bus (SMIB) power system is considered for the numerical investigations. The series compensation of the transmission line is done by either conventional variable

Investigation on TCSC Parameters and Control Structure for SSR Damping in DFIG-Based Wind Farm
International Renewable Energy Congress, 2021The most common method to increase the transmittable power is to insert a fixed series capacitor into a transmission line. But unfortunately, it was noted that the system stability is inversely proportional to the compensation level.

TCSC for Protection of Transmission Line
2010 3rd International Conference on Emerging Trends in Engineering and Technology, 2010A grid of transmission lines operating at high or extra high voltages is required to transmit power from generating stations to load. In addition to transmission lines that carry power from source to load, modern power systems are highly interconnected for economic reasons.

TCDFs based congestion management using TCSC
2012 IEEE Fifth Power India Conference, 2012Transmission system congestion is serious issue for the Independent System Operator (ISO) as it violates the various operating limits of the system. It may also cause increase in the electricity prices. Due to congestion in the transmission network some of the power transactions dispatch may be cancel out.
