This paper presents the study of impact harmonic distortion generated by thyristors controlled series capacitor (TCSC) in Algerian electric power system. By applying Fourier transform terminal voltage and switching function, TCSC model is used as a admittance matrix, frequency domain, then integrated into balanced load flow algorithm based on Newton-Raphson method. The has been carried out with...

Series compensation of transmission lines increase the risk Sub-Synchronous Resonance (SSR) problems. Use Thyristor Controlled Compensators (TCSC) in place Fixed Capacitors (FSC) has benefited terms damping SSR. SSR Damping with TCSC can be achieved supplementary controls or through its inherent capability. discrete time models for small signal stability analysis is well established. This paper...

this paper focuses on multi-objective designing of multi-machine thyristor controlled series compensator (tcsc) using strength pareto evolutionary algorithm (spea). the tcsc parameters designing problem is converted to an optimization problem with the multi-objective function including the desired damping factor and the desired damping ratio of the power system modes, which is solved by a spea ...

This study applies a neural-network-based optimal TCSC controller for damping oscillations. Optimal neural network controller is related to model-reference adaptive control, the network controller is developed based on the recursive “pseudo-linear regression”. Problem statement: The optimal NN controller is designed to damp out the low frequency local and inter-area oscillations of the large po...

This paper presents a study of the performance of numerical distance relay for a 400 kV electrical transmission line compensated by series Flexible AC Transmission System (FACTS) i.e. Thyristor Controlled Series Capacitor (TCSC) is connected in the middle of the transmission line and can be used in voltage mode control or reactive power injection mode, and damping of power system oscillations i...

In this paper, tuning of power system stabilizer (PSS) and thyristor controlled series capacitor (TCSC) is studied. The analysis of mode controllability is used to select the effective location for TCSC. The performances of TCSC equipped with a proportional-integral-derivative controller (P-I-D controller) and proportional-integral-derivative power system stabilizer (P-I-D PSS) are investigated...

With the development of individual wearable electronics, requirements self-energy harvest devices from human skin or motion have increased. A thermal device that receives energy naturally existed in is more attractive than a mechanical harvester needs walking. Herein, thermal-chargeable supercapacitor (TCSC) proposed, which can convert into electrical and then store only by occurring temperatur...

thyristor-controlled series compensator (tcsc) is one of the electric power lines series compensators. tcsc increases transmission system capacity and improves system dynamic and voltage stability. several controllers have been proposed, but most of them generally improve one of tcsc capabilities. in this paper a tcsc robust controller is designed based on nonlinear quantitative feedback theory...

In this paper, a novel approach to analyse, extract and validate the key characteristics of the fault transient phenomena on a thyristor controlled series capacitor (TCSC) compensated transmission line is introduced. This method relies on utilising discrete wavelet transform (DWT) to decompose the traditional busbar voltages and line currents obtained from a single terminal into a series of tim...

In this paper a novel method for finding the fault zone on a Thyristor Controlled Series Capacitor (TCSC) incorporated transmission line is presented. The method makes use of the Support Vector Machine (SVM), used in the classification mode to distinguish between the zones, before or after the TCSC. The use of Discrete Wavelet Transform is made to prepare the features which would be given as th...
