A MATLAB powe flow pogam wi a deailed model of ingle quiel cage induction machine i ued to quantitatively demontate inheent typical weak chaacteitic of e ditibution ytem at make undeiable e ue of lage wind tubine baed on induction geneato. Reult of ee tudie ae hown hee. Index Tem Ditibution feede, eactive powe flow, eactive powe uppot, and wind enegy conveion ytem baed on induction geneato I. INTRODUCTION S eult of inceaing envionmental concen, e A impact of conventional electicity geneation on e envionment i being minimized and effot ae made to geneate electicity fom enewable ouce []. The main advantage of electicity geneation fom enewable ouce ae e abence of hamful emiion and e infinite availability of e pime move at i conveted into electicity [], []. One way of geneating electicity fom enewable ouce i to ue wind tubine at convet e enegy contained in flowing ai into electicity [3]. In ecent yea wind enegy ha become an impotant pat of electical geneation in many countie and it impotance i continuing to inceae [4], [5]. Up to i moment, e amount of wind powe integated into lage-cale electic powe ytem only cove a mall pat of e total powe ytem load [6]. The et of e powe ytem load i fo e laget pat coveed by conventional emal, nuclea, and hydopowe plant. But tendency to inceae e amount of electicity geneated fom wind can be obeved. Theefoe, e penetation of wind tubine in electical powe ytem will inceae and ey may begin to influence oveall powe ytem behavio. In paticula, e new paadigm of ditibuted geneation i F. González-Longatt, E. Gavoki and M. Boliva ae wi Depatment of Electical Engineeing, Univeidad Nacional Expeimental Politécnica de la Fueza Amada, Maacay, Aagua, Venezuela ( fglongatt@ieee.og, juane586@yahoo.com avillaana@yahoo.com cpeazam@cantv.net. F. Gonzalez-Longatt i PhD tudent, Univeidad Cental de Venezuela, Caaca, Venezuela ( flongatt@elecic.ing.ucv.ve. giving ie to inteconnection of mall poduction unit wi e public utility MV o LV netwok [5]. Due to economical and ome technical eaon quiel cage induction machine eult attactive to be ued i wind tubine cheme. It conit of a conventional, diectly gid coupled quiel cage induction geneato. The lip, and hence e oto peed of a quiel cage induction geneato vaie wi e amount of powe geneated. Thee oto peed vaiation ae, howeve, vey mall, appoximately to pe cent. Theefoe, i wind tubine type i nomally efeed to a a contant peed o fixed peed tubine [7]. The wind tubine ytem uing taditional quiel cage induction machine i attactive to be connected on ditibution ytem, but a geat numbe of geneation unit peent ome technical challenge to utilitie. In i pape e teady tate effect of high penetation level of wind tubine uing quiel ingle cae induction geneato. II. MODELING It i well known at ditibution netwok ae typically adial and paive, wee deigned fo one diection powe flow. The inteconnection of wind tubine geneato inject powe in diffeent point of e netwok, whee only conumption have been peviouly planned. Theefoe e peence of i geneation unit in MV ditibution netwok can caue eveal poblem, namely: Voltage egulation difficultie at e HV/MV ubtation. Shot-cicuit level inceae; The need fo potective device coodination; Tanient voltage dip eulting fom induction geneato inteconnection. Thee fact ae peenting technical challenge to e utilitie. In ode to evaluate e impact of wind tubine on ditibution netwok, imulation mut be developed to ovecome e technical opeation poblem and enue a afe and eliable opeation. Thi pape i focalized on detemine e effect of high penetation level of wind tubine wi induction geneato on voltage egulation and powe loe; in ode to evaluate e impact on ee vaiable teady tate imulation mut be doing; load flow analyi. When a wind tubine o wind fam wi ingle cage induction machine geneation i to be include in a load flow

Single Squiel Cage Induction Geneato-Wind Tubine A way to imulate a wind tubine i to aume a geneated active powe and a given powe facto, wi witch e conumed eactive powe i calculated.

The active powe i calculated fom e wind peed fo i fit iteation of e powe flow analyi, and fom en it value i emain a a contant. The eactive powe depend on e active powe and e bu voltage. In i cae, we ae decided calculating e eactive powe a a function of e voltage.
