The connection of large amounts of wind power generation poses new challenges for the dynamic voltage stability analysis of an electric power system, which has to be studied. In this paper, the traditional Doubly-Fed Induction Generator model is employed. Based on this model, a crowbar and chopper circuit is set up to protect the turbine during the short-circuit period. The EUROSTAG software package was used for the simulation studies of the system, and numerical results were obtained. Conclusions are drawn that provide a better understanding of the influence of crowbar and chopper protection on Doubly-Fed Induction Generators (DFIG), during low voltage ride through, in a system with wind power generation.<\/jats:p>","DOI":"10.3390\/en11040885","type":"journal-article","created":{"date-parts":[[2018,4,10]],"date-time":"2018-04-10T13:06:08Z","timestamp":1523365568000},"page":"885","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Influence of Crowbar and Chopper Protection on DFIG during Low Voltage Ride Through"],"prefix":"10.3390","volume":"11","author":[{"given":"Rita","family":"Monteiro Pereira","sequence":"first","affiliation":[{"name":"IPC\/ Instituto Superior Engenharia de Coimbra (ISEC), Instituto Superior Engenharia de Coimbra, 3030-199 Coimbra, Portugal"}]},{"given":"Adelino","family":"Pereira","sequence":"additional","affiliation":[{"name":"IPC\/ Instituto Superior Engenharia de Coimbra (ISEC), Instituto Superior Engenharia de Coimbra, 3030-199 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8462-1215","authenticated-orcid":false,"given":"Carlos","family":"Ferreira","sequence":"additional","affiliation":[{"name":"IPC\/ Instituto Superior Engenharia de Coimbra (ISEC), Instituto Superior Engenharia de Coimbra, 3030-199 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1065-2371","authenticated-orcid":false,"given":"Fernando","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Faculdade de Engenharia da Universidade do Porto, 4200-465 Porto, Portugal"},{"name":"The Institute for Systems and Computer Engineering, Technology and Science (INESC TEC), 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Widanagama Arachchige, L.N., Rajapakse, A.D., and Muthumuni, D.
