Summary: | Device generating electrical disturbances in the grid connected to a system for generating electrical energy, such as a wind turbine or a solar plant, in order to test the response of generators to disturbances in the grid, disturbances being understood as voltage dips, voltage surges, phase jumps and frequency changes, which comprises a three-phase transformer or three single-phase transformers having variable taps connected in series between the collector system and the generator, said transformer being responsible for producing voltage surges, voltage dips and phase jumps by means of the switching of a bypass branch with an impedance with the branch that contains the transformer, there likewise being a battery of capacitors arranged in parallel for producing voltage surges with the aid of series impedance and/or resistance. In addition, there is a reducer transformer arranged in parallel, which is connected to a rectifier, and the latter is connected to resistances for testing the response to frequency variations.
Equipo generador de perturbaciones eléctricas en la red conectada a un sistema de generación de energía eléctrica, como por ejemplo un aerogenerador o planta solar, para ensayar la respuesta de los generadores ante perturbaciones en la red, entendiendo perturbaciones como huecos de tensión, sobretensiones, saltos de fase y cambios de frecuencia, que comprende un transformador trifásico o tres monofásicos de tomas variables conectados en serie entre el sistema colector y el generador, encargándose este transformador de realizar sobretensiones, huecos de tensión y saltos de fase, mediante la conmutación de una rama de bypass con una impedancia con la rama que contiene el transformador, disponiendo asimismo en paralelo de una batería de condensadores para realizar sobretensiones con ayuda de una impedancia y/o resistencia serie. Además dispone en paralelo de un transformador reductor conectado a un rectificador, y éste a unas resistencias para ensayar la respuesta ante variaciones de frecuencia. |
