:采用海水开式循环的电厂循环水系统容易受到水质的影响,尤其是海水水藻的污染。水藻不仅影响凝汽器的换热效率,还可能堵塞循环水系统甚至损坏系统中的相关设备。文中介绍了某电厂水藻堵塞循环水旋转滤网后采用的若干解决方法,如增加保护逻辑,增设拦污浮筒,增加二次滤网连续冲洗程序,积极联系地方水利部门等措施。通过这些措施,大大减少了水藻带来的影响,并顺利完成了满负荷试运行。:循环水系统;水藻;应对策略:TK228:B:10090665(2014)02007902,。2660MW,,。1,,,,,,。12660MW,,。,,。D3024×14,(2×3.0m×3.0m)。、、、、,、、、。1,13。22.1,,,,,,,,于强1,彭辉2(1.,210031;2.,211002)收稿日期:2013-10-17;修回日期:2013-12-131/m16.1/(m3·h-1)3744088LKXA141MMMMABAB~~2/(m·s-1)0.8/mm6.43×6.43/mm3500XKC35003/mm5/h0~99()/kPa6~12()/min0~10()EDF2200JiangsuElectricalEngineering2014333279,69,,。6,,,,。,,4,22,。2.2DCS,,0.6m,2。1.6m,3。2.3,,。,。2.4,,,。,,,,。3,(2、3),“1.4m,”。,,DCS“/”,,,。,,“,”,DCS“/”。,1.7m,。,。,,,,,2。,,。,,168h,4。4(1),,;,。(2),,,。:1.J.,1987(4):255256.2,.J.,2002(3):5963.2300250200150100500024681022:0002:0006:0010:0014:0018:0022:00I/AL/m5B5B3300250200150100500024681013:5714:0314:0914:1514:2114:2714:33I/AL/m5B5B4300250200150100500024681022:0002:0006:0010:0014:0018:0022:00I/AL/m5B5B(下转第84页)80,。,、,,,。:1.J.,2011,35(6):16.2.1000kVD.:,2012.3,,,.1000kVJ.,2009(S1):7374.4.1000kVD.:,2012.5,.J.,2007,27(36):16.6,,,.1000kVJ.,2009(33):7072.7,.1000kVJ.,2006,30(15):16.8,,,.J.,2008,28(34):1219.9,,,.J.,2009,33(10):5558.:(1985),,,,;(1982),,,,;(1988),,,,;(1979),,,,。AReviewonOperationandMaintenanceofUHVACTransmissionLineGAOSon1,LIUYang1,LUYongling1,CUIYandong2(1.JiangsuElectricPowerCompanyElectricPowerResearchInstitute,Nanjing,211103,China;2.JiangsuElectricPowerMaintenanceBranchCompany,Nanjing211102,China)Abstract:TheoperationandmaintenanceofUHVACtransmissionlineinChinaisreviewedinthispaper.BasedonthepracticalexperienceofChina'sfirst1000kVACUHVtransmissionline,theoperationcharacteristicsofUHVtransmissionlinearesummarized.Theresearchonandapplicationofanti-accidentmeasuresandkeytechnologyforUHVtransmissionlinesarealsointroduced.Thedataprovidedinthispapercanbetakenasareferenceforfurtherstudyofoperationandmaintenancetechnology,soastoguaranteeUHVpowergrid'ssafety.Keywords:ACUHV;transmissionline;operationandmaintenance;presentapplicationsituation;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;(上接第80页)AnalysisonAlgae-blockageinOpenCirculatingWaterSystemsofPowerUnitsandSolutionMeasuresYUQiang1,PENGHui2(1.GuodianElectricalPowerResearchInstitute,Nanjing210031,China;2.JiangsuFrontierElectricalPowerTechnologyCo.Ltd.,Nanjing211102,China)Abstract:Powerplantcirculatingwatersystemsadoptingseawatercoolingcanbeeasilyaffectedbythequalityofwater,especiallythealgaeintheseawater.Algaenotonlyinfluencestheefficiencyofcondenser'sheattransfer,butalsocanblockorevenbreaktheassociatedgearofthecirculatingwatersystems.Thispaperintroducessomemethodsaimingtosolvetheblockingofrotaryfilteringnetaffectedbyalgaeinsomepowerplants,suchasincreasingprotectionlogic,installingtrashfloats,addingsecondaryfiltercontinuousflushingprogram,andactivelycontactingthelocalwaterconservancydepartmentsandsoon.Withthesemeasures,theeffectsofthealgaewereeffectivelysuppressed,andtheplantsuccessfullycompletedthefullloadtest.Keywords:circulatingwatersystem;algae;solutionmeasures:(1985),,,,;(1967),,,,。84
