300MW机组循环水泵的在线优化运行 Abstract Thispaperdiscussestheoptimizationofonlineoperationfor300MWpowerunitcirculatingwaterpump.Theimportanceofoptimizingtheoperationofcirculatingwaterpumps,themainfactorsaffectingtheoperationandthecorrespondingoptimizationmeasuresareanalyzed.Theoptimizationmeasuresmainlyincludeadjustingtheoperatingconditions,improvingtheequipmentmaintenancelevel,implementingreal-timemonitoringandcontrol,andusingadvancedtechnologies.Throughtheoptimizationofonlineoperation,thelifespanofthecirculatingwaterpumpcanbeextended,theenergyconsumptioncanbereduced,andtheeconomicbenefitsoftheunitcanbeimproved. Introduction Asanimportantpartofthepowergenerationsystem,thecirculatingwaterpumpisresponsiblefordeliveringwaterfromthecoolingtowertothecondensertocoolthehigh-temperaturesteamgeneratedintheboiler.Thenormaloperationofcirculatingwaterpumpsiscriticaltoensurethestablepowergenerationoftheunit.Therefore,optimizingtheoperationofcirculatingwaterpumpshasimportantpracticalsignificancetoimprovetheeconomicbenefitsofpowerplants. TheImportanceofOptimizingtheOperationofCirculatingWaterPumps Thenormaloperationofcirculatingwaterpumpsisdirectlyrelatedtothestabilityofunitoperation,economicbenefits,andenvironmentalprotection.Theinefficientoperationofthecirculatingwaterpumpwillincreasetheenergyconsumption,reducetheoperatingefficiency,andultimatelyaffecttheeconomicbenefitsoftheunit.Moreover,thecirculatingwaterpumpisanimportantwatersourceforthepowerplant,andanyissueswiththepumpcanhaveasignificantimpactonthewateruseandtheenvironmentintheplant. FactorsAffectingtheOperationofCirculatingWaterPumps Theoperationofcirculatingwaterpumpsisaffectedbymanyfactors,suchasthedesignofthepump,theoperatingconditions,themaintenanceleveloftheequipment,andthecontrolmode.Thecommoncausesofinefficientoperationincludetheagingoftheequipment,theunbalancedwatersupplyanddrainage,theimproperadjustmentofthesystem,andthelackofreal-timemonitoring.
