In this paper, voltage sag due to power system faults such as three-phase-to-ground, single-phase-to-ground, phase-to-phase and two-phase-to-ground are created in transmission line model for generation of different types of voltage sag. This paper describes a methodology for voltage sag generation using Matlab/Simulink. It includes fault simulations for generation of different types of voltage sag...
Dramatic increase in electric energy demand results the power system network to span in a large scale, consequently increasing the possibility of power disturbances, which may lead towards major blackouts. Therefore the power system stability is of prime importance and mainly influencing factors such as rotor angle stability, frequency stability and voltage stability. This paper discusses the overall...
The resonance fault current limiter (RFCL), which avoids the disadvantages of the series reactor, is feasible for EHV and UHV grid. To contribute to project application of the RFCL, and study its running characteristic and impact on relay protection, the dynamic simulation lab of State Grid simulation center carries out the research on simulation technique for RFCL. The principle and technical properties...
