TCSC for Protection of Transmission Line

2010 3rd International Conference on Emerging Trends in Engineering and Technology, 2010
A 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.

Enhancement of TCSC characteristics

2017 International Conference on Intelligent Computing, Instrumentation and Control Technologies (ICICICT), 2017
Trending problem in today's scenario is heavy loaded lines. Power flow in the transmission line can be controlled by using FACTS devices which varies the line reactance and voltage. Series compensating devices such as Thyristor controlled series compensator (TCSC) and Thyristor controlled reactor (TCR) are used to control the line reactance. In general,

Impact of TCSC on the protection of transmission lines

2006 IEEE Power Engineering Society General Meeting, 2006
This paper presents a comprehensive analysis of the impact of TCSC on the protection of transmission lines. The TCSC is considered as a dynamical device and its transient process is modeled in order to have the response to disturbances based on its own control strategy. It is shown that not only the TCSC affects the protection of its line, but also the

Performance of a TCSC for congestion relief

2005 IEEE Russia Power Tech, 2005
This paper presents a method to determine the performance of relieving congestions using a thyristor controlled series capacitor (TCSC) in a transmission network by comparing locational marginal prices (LMP). The method allows to study different parameter variations - e.g. varying demand or size of the TCSC.

Power oscillation compensation by TCSC

2015 International Conference on Advanced Computing and Communication Systems, 2015
A 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.

Performance of installed TCSC projects

India International Conference on Power Electronics 2010 (IICPE2010), 2011
This paper presents brief investigations on performance of Installed Thyristor Controlled Series Compensator (TCSC) projects world around. The main and basic objective of TCSC's in power system is to enhance power flow and improve system stability. The deployment of TCSC in transmission line also improves SSR mitigation, Power Oscillation Damping (POD)

TCSC control for longitudinal network

IEEE/PES Transmission and Distribution Conference and Exhibition, 2003
This paper proposes a new TCSC control scheme for integrated power systems realizing many number of TCSC in complex power systems. The proposed method is based on pseudo inverse, DC power flow, and linear quadratic control (LQR) methodology. DC power flow equation is usually used to make a relationship between power flows and phase angles but this is ...

Analytical Modeling of TCSC Dynamics

IEEE Transactions on Power Delivery, 2005
This 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 ...

Description of the Internal State of TCSC

Power and Energy Systems, 2011
ABSTRACT The description of the internal state of thyristor controlled series capacitor (TCSC) is presented in the paper. The model developed for this description is based on the firing angle of the thyristor. Simulations showed that the model is capable of identifying the internal state of TCSC.

Transient stability control of TCSC

2009 4th IEEE Conference on Industrial Electronics and Applications, 2009
This 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 ...
