This paper describes a new relaying algorithm for the protection of transmission lines with a Thyristor Controlled Series Compensator (TCSC). The algorithm is based on the pattern of traveling waves generated during a fault event. Several tools like modal analysis, the discrete wavelet transform and a probabilistic neural network trained to work with the energy contained in the wavelet transform coefficients...
This investigation presents the implementation and simulation of a Simulink-based controlled permanent magnet synchronous generator (PMSG) wind turbine in the dq0 reference frame. The model consists of a current control subsystem, a PMSG model, a mechanical subsystem, a pitch angle controller and a wind turbine model. The current control subsystem makes use of PI controllers governing the wind turbine...
This work analyzes the capabilities of ride-through-fault (RTF) of a double-fed induction machine (DFIG), -based wind farm connected to a VSC-, in case of a fault in the DC side of the VSC. The modelling of the DFIG wind turbine takes into account key aspects that intervene in succeeding the fault ride-through such as the power capacity of its electronic converter and its control scheme. As result...
This paper presents a steady state performance analysis carried out to evaluate the operation and behavior of a two VSC-based level-full scale frequency converter working as a HVDC link. The digital model has been implemented and evaluated using PSCAD/EMTDCcopy. The emphasis of this work has been put on evaluating the transferred active and reactive power from the rectifying station to the inverting...
This paper presents a steady state performance analysis carried out to study the behavior of a two VSC-based operating as a single-input single output HVDC link. The digital model of the HVDC link has been implemented and evaluated using PSCAD/EMTDC. The emphasis of this research work has been focused on evaluating the transference of active power from the rectifying station to the inverting station...
The focus of this paper is to report key aspects of the laboratory-level performance on a three-phase, scaled-down thyristor controlled series capacitor, TCSC, prototype. All-important issues concerned to the design and construction of the prototype are included in this work. The testing of the TCSC prototype is restricted to steady-state conditions. Several experimental cases are presented
