Research on Impedance Characteristics of Thyristor Controlled Series Capacitor

2010 Asia-Pacific Power and Energy Engineering Conference, 2010
The desired impedance of Thyristor Controlled Series Capacitor (TCSC) is usually obtained by adjusting the firing angle and it is of great importance to make clear the relationship between the two quantities. The relationship between firing angle and conduction angle is proposed in this paper considering the influence of the thyristor conduction ...

SSR analysis with dynamic phasor model of thyristor-controlled series capacitor

IEEE Transactions on Power Systems, 1999
In their previous work, the authors have studied the phasor dynamics of thyristor-controlled series capacitors (TCSCs), and derived associated models for studying power swing oscillations in power systems. This paper presents the use of a dynamic phasor model of the TCSC in studies of subsynchronous resonance (SSR).

Application of TID controller in AGC with Thyristor Controlled Series Capacitor

2015 International Conference on Electrical, Electronics, Signals, Communication and Optimization (EESCO), 2015
The variation in load on a power system is unpredictable because it causes drifts in frequency and voltage apart from their nominal values thus resulting in loss of generation due to the tripping of lines and even blackouts. So an approach has been undertaken for investigating the load frequency control problem in a power system consisting of two non ...

Tuning of thyristor-controlled series capacitors by eigenvalue sensitivity analysis

Proceedings of 36th Midwest Symposium on Circuits and Systems, 2002
In this paper, a systematic method for the tuning of multiple power system controllers using eigenvalue sensitivity and linear programming is presented. The main feature of this method is the symbolic formulation of the eigenvalue increment and its universal applicability to FACTS controllers. The proposed method is applied to a single machine infinite-

GA based optimisation of thyristor controlled series capacitor

2007 42nd International Universities Power Engineering Conference, 2007
This paper presents a genetic algorithm (GA) to seek optimal placement of a FACTS device - thyristor controlled series compensator (TCSC). The optimization is done on two parameters, optimal location and optimal value of compensation. The total transfer capability (TTC) is applied as a measure of power system performance.

Voltage sag mitigation by means of thyristor controlled series capacitors

8th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.98EX227), 2002
This paper describes the mechanism by which the thyristor controlled series capacitor (TCSC) is able to mitigate voltage sags. It also investigates and illustrates the use of TCSCs for mitigating voltage sags in both a radial power system and an interconnected one.

A thyristor controlled series capacitor design for research laboratory application

1999 IEEE Africon. 5th Africon Conference in Africa (Cat. No.99CH36342), 2003
This paper discusses the theory of operation of the thyristor controlled series capacitor (TCSC), and describes the design of a prototype, laboratory-scale TCSC to meet a specific range of capacitive reactance values suited to a research laboratory application. Simulated and measured results of the designed TCSC are presented to verify the soundness of

An application of thyristor controlled series capacitor to single-pole reclosing

Engineering Solutions for the Next Millennium. 1999 IEEE Canadian Conference on Electrical and Computer Engineering (Cat. No.99TH8411), 2003
This paper presents an adaptive short-time compensation and reclosing technique for improving power system stability and reducing turbine-generator shaft torsional torques. The fundamental concept of the proposed technique is to interrupt single line-to-ground faults on double-circuit transmission lines using single-pole switching.

A new modeling and control scheme for thyristor-controlled series capacitor

Journal of Control Theory and Applications, 2009
In order to design an optimal controller for the thyristor controlled series capacitor (TCSC), a novel TCSC control model is developed. In the model, the delay angle of thyristor valves is the input, and the inductor current is chosen as the output. Theoretical analysis and simulation studies show that TCSC is a non-linear system and its parameters ...
