This paper presents a novel study for SSR mitigating in the wind power systems based on DFIG using GCSC (Gate controlled series capacitor). The GCSC is composed of three pairs of anti-parallel GTO Thyristors (Gate Turnoff) connected in parallel with a fixed capacitor. The GCSC is applied to reduce inrush current in capacitor compensator during the transient operation by executing a proper firin...

In this paper the control strategies of svc are described.SVC is used to stabilize the voltage profile in a grid system.In the designing of SVC there is a combination of three TSC’s and one TCR.The SVC consists of a group of shunt connected capacitor banks and inductors with fast speed of response afforded by thyristor switching. The SVC provides the required amount of reactive power compensati...

Summary Modern power networks are enormously complex and frequently interconnected by weak tie‐lines, which results in a variety of stability issues such as low frequency oscillations (LFOs). LFOs can have negative impact on system tie‐line transmission capacity, resulting catastrophic blackouts if suitable damping control mechanisms not situ. This article demonstrates robust design for inter‐a...

This paper investigates the role of Static Var Compensator (SVC) on stability of voltage in grid system due to the presence of harmonics.. Here the design of SVC is based on the combination of Thyristor switched capacitors (TSC’s) and Thyristor controlled reactor (TCR) . TSC’s are used for switching the capacitor banks on and off while the TCR continuously controls the reactive power by varying...

This paper discusses control design issues for the existing thyristor controlled series compensation (TCSC) device at Slatt substation on the Slatt–Buckley 500-kV transmission line owned by BPA. The controls were developed at Washington State University (WSU) in a project funded by Bonneville Power Administration (BPA). The project has been carried out in close collaboration between the WSU tea...

Non-dominated Sorting in Genetic Algorithms-II (NSGA-II) is a popular non-domination based genetic algorithm for solving multi-objective optimization problems. This paper investigates the application of NSGA-II technique for the design of a Thyristor Controlled Series Compensator (TCSC)-based controller and a power system stabilizer. The design objective is to improve both rotor angle stability...

This paper presents a study on optimal location and sizing of multiple FACTS devices based on Particle Swarm Optimization (PSO) for minimization of transmission losses, and voltage profile improvement, which takes into account the cost of installation. In this study, Static Var Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC) are chosen as the compensating device for the pur...

This paper demonstrates the phase imbalanced series capacitive compensation concept to enhance power system dynamics as it has the potential of damping power swing as well as sub synchronous resonance oscillations. A scheme for a phase imbalanced capacitive compensation is shown. It is a “hybrid” series compensation scheme, where the series capacitive compensation in one phase is created using ...
