Investigation on Full-Converter-Based Wind Power Plant Behavior During Short-Circuits

This paper presents an investigation on the behavior of a full-converter-based wind power plant (FCWPP) during short-circuits. To do so, an actual power network is taken into account, in which a transmission line that connects a FCWPP to a traditional system fed by typical high inertia generation units is studied. The test system was modeled and tested by means of Electromagnetic Transients Programs (EMTP), namely Alternative Transients Program (ATP) and Power System Simulator (PS SIMUL). Single-phase fault scenarios at different positions on the studied line were tested and then, voltage and current characteristics at both terminals were investigated. The obtained results show that the FCWPP control leads voltages and currents to present different patterns from those verified when typical synchronous machines are considered, which can impair monitoring functions or even interfere disturbance analysis studies.
