2 1. Intoduction Since the emegence of gid-connected wind geneation in 1980, with the development of blade aeodynamic, compute technology [1], contol technology, geneato technology and new mateial, the development of wind powe geneation technology i vey apid. The unit capacity ha developed fom the initial eveal kilowatt-cla to megawatt-cla which ente the wind fam ecently. The development of powe contol mode i fom fixed pitch tall contol to full paddle blade vaiable-pitch and vaiable peed contol [-4]. The opeating eliability ha inceaed fom 50% in ealy 1980 to moe than 98%. And the wind powe geneato in the wind fam can ealize centalized contol and emote contol. The development pace of wind fam i moe wide, moving inland fom the ea. Developed countie have made emakable achievement in the development and utilization of wind enegy. foming a wind mill induty on a vat cale. In Octobe 001, the global wind powe geneation intalled capacity ha beaked 0 thouand MW [5-7]. The new capacity eached 5000MW. Expet pedict that the global wind tubine intalled capacity will continue to inceae at an annual ate of moe than 5% fom 00. By 010, the wold wind tubine intalled capacity will beak- 100GW [8-10]. Wind powe geneation technology develop towad the diection of inceaing ingle-machine capacity, alleviating the unit volume and impoving the efficiency [11-1]. Taking ingle machine capacity a an example, in the ealy 1980, ingle-machine capacity of commecialized wind tubine mainly i 55k W. Fom mid-1980 to ealy1990, it i mainly 100~450k W. In the middle of and late 1990, it i mainly 500K W~1MW [13-15]. At peent, the lage-cale and medium-ized unit connected to the gid ha become the main fom of wind powe utilization. Fo educing the cot pe kilowatt, aving the utilization aea of wind fam, acceleating the contuction peed of wind fam, impoving the economic benefit of wind powe, many wind powe manufactue ae committed to impoving ingle-machine capacity, poducing the commecial unit whoe capacity i geate than 1MW [16-18]. The fixed pitch contant peed wind tubine which ente the wind fam in the mid-1980 mainly olve the poblem of ynchonization of wind powe et and the afety and eliability of opeation. The ue of oft cut-in technology, aeodynamic baking technology, yaw and automatic untwiting technology ae the mot baic poblem of wind geneating et in gid connected opeation need to olve [18-0]. The oft cut-in technology adopt the oft cut-in method baed on bidiectional thyito to ynchonize and cloe the aynchonou geneato technology. The aeodynamic bake technology efe to 1.5~.5m pat in the tip of the blade, which i deigned to the teeable the leaf opex poile. When wind tubine need to take off the netwok and top [1-3], the leaf opex poile can otate 90 degee to fom the pilling flap accoding to the contol intuction action, which caue the wind wheel peed to dop apidly. Automatic untwiting technology efe to that when the engine oom ha been adjuted to 70 degee in tandby tate, o ha been adjuted to 1080 degee in the unning tate [4], The geneato cable intoduced to the towe fom the cabin ae in the tate of winding engine, then the contolle will epot the fault, and the wind tubine will be hutdown and automatically execute unwapping. Afte untwiting, the fault ignal i eliminated and the contolle i eet automatically [5-6]. Becaue the powe output i limited by it pefomance of the blade, the pitch angle of blade ha been fixed duing intallation. The geneato peed i limited by the gid fequency. Theefoe, in the allowable ange of the wind peed, the contol ytem of fixed pitch wind tubine in the unning poce doen t make any contol fo the change of output enegy caued by wind peed. Thi geatly implifie the contol technology and the coeponding evodive technology. So that the fixed pitch wind tubine can be commecialized in a hot time. In the ealy day, the contant peed contant pitch wind tubine ae made in Denmak [7]. Thi contol concept i called Danih concept windmill. In 1990, the eliability of wind tubine i not a poblem. The vaying oa ditance wind tubine began to ente the wind fam. The vaying oa ditance technology efe to that the blade can otate aound the axi. The contant peed wind tubine with vaiable pitch can be ued to contol otate peed on tatup.the powe can be contolled on gid-connection. The tating ability and powe output chaacteitic of the wind tubine ae impoved ignificantly. Becaue the effect of vaying oa ditance contant peed wind tubine unde the ated wind peed i not ideal. In the mid and late 1990, A vaiety of vaiable peed wind tubine baed on powe electonic technology began to ente the wind fam. Accoding to the capacity contol way of the blade, the vaiable peed wind tubine include two type: the vaiable peed fixed pitch tall contol concept unit and the vaiable peed vaying oa ditance contol concept unit. the development of vaiable peed vaying oa ditance unit i ipe [8]. Many MW cla commecial opeation unit ue thi contol mode, but it equie a cotly and complicated popelle pitch angle egulatoy ytem. The vaiable peed fixed pitch tall contol unit i till in the expeimental tage. The obviou advantage of thi model leave out the popelle pitch angle egulatoy ytem. The tall contol mode depend on the ditinctive aifoil tuctue of blade. The molding technology i difficult. In ecent yea, with the inceaing of equiement lagecale and elevancy in wind powe geneation technology, the cloud computing technology i intoduced to the elevant pactical application. The wind tubine ha gadually become the pilla of lage powe gid in powe geneation. At the ame time, people have moe and moe equiement on the wind powe geneato gid connected ytem with enegy aving 433 BOLETIM TECNICO DA PETROBRAS

3 effect. Theefoe, it ha geat value to tudy and impove the method fo egulating and contolling the wind powe ytem capacity [9-30]. Expet and chola have been committed to the eeach thi tudy. Howeve, due to the geat change of the coelation of the cloud computing, the egulation of convete i difficult to maintain tability. It bing geat difficultie to eaonable egulation. The taditional PID tability contol method in the cloud computing envionment i difficult to maintain the tability of the convete with taking a long time. The enegy aving contol method i moe complicated. Fo olving the above poblem, fit of all thi pape analye the woking poce of peed of hip geneato et detailedly. Fom the genetic algoithm, the taditional PID contol poce i impoved. Though the well-deigned fitne function and genetic opeato, we cay out enegy-aving contol of intelligent contol of peed of hip geneato et unde the cloud computing, making the geneato et unde the maive cloud computing complete contol quickly. The expeimental eult how that thi method ha pefeable contol effect in the cloud computing envionment.. Dynamic Chaacteitic of Wind Tubine and It Influence on Contol Sytem (1) The contol taget of wind tubine Fom the above analyi, wind tubine ytem have tong nonlinea multivaiable with many uncetain facto and ditubance. The baic goal of the wind powe geneation contol ytem i divided into fou level: enue eliable opeation, get maximum enegy, povide good powe quality, polong the gea et life. The contol ytem hould achieve the following pecific function: (1) enue the table opeation of the ytem in the woking wind peed ange. when the wind peed i low, tack the optimal tip peed atio to achieve maximum wind powe captue. (3) when the wind peed i high, the wind enegy captue i limited, keep ated output powe of the wind tubine. (4) educe toque peak change caued by gut, educe the mechanical te of the wind wheel and the fluctuation of output powe. (5) educe tanient epone of powe geaing chain. (6) le contol cot. The amplitude of input ignal hould be limited, fo example, the adjutable ange of popelle pitch angle and vaying oa ditance ate. (7) eject the fequency may caue the mechanical eonance. (8) adjut the output powe of unit, contol tability of gid voltage and fequency Dynamic chaacteitic of wind geneating et (1) High non-lineaity Baez theoy aume that the wind wheel i ideal. It ha no wheel bo, but ha infinite blade. The aiflow pae though the wind wheel without eitance. Suppoing that the ai flow i unifom when it pae though the wept uface of the whole wind wheel. Ai cuent diection i axial. The maximum powe coefficient of Baez theoy i 59.3%. Thee i a big diffeence between the wind tubine blade in actually unning and aumed condition of Baez theoy. The wind wheel i in the wind envionment in which the wind peed and wind diection i tochatic vaiable. Blade ha tip lo and wake loe, hub loe. The dag coefficient inceae and the lift coefficient educe afte the blade tall. Thee facto affect the ditibution of powe facto PC cuve Fequent tochatic witching chaacteitic of vaiable peed wind tubine opeating condition Theoetically, the output powe of wind tubine i infinite. It i a cube function of the wind peed. In fact, due to the limitation of mechanical tength and geneato ating, the output powe i limited. Vaiable peed wind tubine ae limited with two fundamental limitation: powe and baed peed limit. The powe cuve of wind tubine ha geat diffeence with diffeent type and manufactue of wind tubine. Geneally the vaiable-peed unit i compoed of thee opeating cuve. When the wind peed i low, the peed change with wind peed, keeping the optimal tip peed atio to achieve maximum wind enegy captue. The popelle pitch angle i the optimal value. With the wind peed inceae, the peed limit i achieved, theeafte, until the maximum toque. The maximum peed i kept table. (3) The uncetainty of effective wind peed The wind wheel i in a thee dimenional time-vaying wind field envionment. Due to diffeent wind peed ditibution on the whole otating plane of wind wheel, and it i affected by tubulence, towe and uface oughne, the wind peed meaued by uing the anemocope on top of the cabin i inaccuate. Even if the wind peed meaued by the anemomete i accuate, it i only a little wind peed. So the effective wind peed can not be meaued diectly. (4) Many intefeence facto Thee ae many eo ouce and uncetaintie influenced the pefomance of wind tubine. Fo example, the change of Reynold numbe will caue the powe eo with 5%. The ediment and ain on the leave can caue 0% powe change. Othe facto-like the unit aging, atmopheic condition, gid voltage and fe- SEPTEMBER

(5) The nonlinea and co coupling chaacteitic of doubly fed induction geneato The tato winding of the doubly fed induction geneato i diectly connected to the electified wie netting. The oto winding i connected with the powe gid though the AC-DC-AC cicle fequency convete. Accoding to the change of peed, wind powe geneation ytem egulate the fequency of excitation cuent, ealizing the contant fequency output. Changing the amplitude and phae of the excitation cuent make the independent egulation of active powe eactive powe be ealized. In thi plan, the convete only need to upply the lip powe, which geatly educe the demand fo capacity. It i uitable fo the vaiable peed contant fequency wind geneation ytem. 3. Contol Subject Selection of Cloud Computing Technology Wind Tubine Geneato When analyzing the contol chaacteitic of cloud computing wind powe geneation ytem, the opeation model of peed of hip geneato et voltage DFIG in teady tate condition need to be analyzed.
