Controlled Islanding with Vsc-hvdc Links Acknowledgements
Controlled islanding has been widely discussed in the literature as a novel concept for the power system protection. However, the islanding can result in unbalanced islands where the power mismatch will often cause an instability that can lead either to a subsequent load shedding or generator tripping within the islands. Controlled VSC-HVDC links can mitigate the negative consequences of the co...
متن کاملDynamic Harmonic Modeling and Analysis of VSC-HVDC Systems
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...
متن کاملDamping of Subsynchronous Resonance Using a Vsc-hvdc Link
A possible detrimental effect of onshore series compensation in the GB grid is the appearance of subsynchronous resonance (SSR). In this paper, a control scheme for a VSC-HVDC link capable of damping subsynchronous oscillations is proposed in order to effectively counteract the potential damage caused by SSR in steam turbines. The VSC-HVDC link has been modelled to maintain its primary function...
متن کاملUnderstanding of tuning techniques of converter controllers for VSC-HVDC
A mathematical model of a voltage source converter is presented in the synchronous reference frame for investigating VSC-HVDC for transferring wind power through a long distance. This model is used to analyze voltage and current control loops for the VSC and study their dynamics. Vector control is used for decoupled control of active and reactive power and the transfer functions are derived for...
متن کاملAnalysis and Improving Reliability Indices of VSC-HVDC transmission system tapped by a VSC- station
During the last three decades, reliability analysis of power systems considering transformers, breakers, transmission lines, and generators failure has been widely applied. This analysis has been done especially in the generation and transmission levels and is mainly restricted to high voltage alternating current (HVAC) systems. HVDC transmission systems are becoming increasingly popular when c...
