One of the requirements is the ride-through fault capability (RTFC), i.e., the system capability to sustain operation during voltage sags. In this sense, the present paper intends to investigate the behavior of a full-converter wind generator with a permanent magnet synchronous machine during symmetrical and asymmetrical voltage sags. Two solutions to improve the low voltage ride-through capability (LVRT) of this technology are analyzed: discharging resistors (brake chopper) and resonant controllers (RCs). The design and limitations of these solutions and the others proposed in the literature are discussed. Experimental results in a 34 kW test bench, which represents a scaled prototype of a real 2 MW wind conversion system, are presented.<\/jats:p>","DOI":"10.3390\/en9010059","type":"journal-article","created":{"date-parts":[[2016,1,20]],"date-time":"2016-01-20T11:19:41Z","timestamp":1453288781000},"page":"59","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Low Voltage Ride-Through Capability Solutions for Permanent Magnet Synchronous Wind Generators"],"prefix":"10.3390","volume":"9","author":[{"given":"Victor","family":"Mendes","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais 31270-010, Brazil"}]},{"given":"Frederico","family":"Matos","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical Engineering, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais 31270-901, Brazil"},{"name":"Department of Electrical Engineering, Federal University of Itajub\u00e1, Itabira, Minas Gerais 35903-087, Brazil"}]},{"given":"Silas","family":"Liu","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical Engineering, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais 31270-901, Brazil"}]},{"given":"Allan","family":"Cupertino","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical Engineering, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais 31270-901, Brazil"},{"name":"Department of Materials Engineering, Federal Center for Technological Education of Minas Gerais, Belo Horizonte, Minas Gerais 30421-169, Brazil"}]},{"given":"Heverton","family":"Pereira","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical Engineering, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais 31270-901, Brazil"},{"name":"Department of Electrical Engineering, Federal University of Vi\u00e7osa, Vi\u00e7osa, Minas Gerais 36570-900, Brazil"}]},{"given":"Clodualdo","family":"De Sousa","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Federal University of Itajub\u00e1, Itabira, Minas Gerais 35903-087, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2016,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"308","DOI":"10.1049\/iet-rpg.2008.0070","article-title":"A review of grid code technical requirements for wind farms","volume":"3","author":"Tsili","year":"2009","journal-title":"IET Renew.
