摘　　要：在我国煤炭资源丰富但水资源匮乏的山西省北部,冬天寒冷且持续很长时间,主要以西北风为主,白天时间短暂且天气干燥。直接空冷技术凭借其较小的占地面积和节约水资源的优势,成功替代了水冷系统来冷却发电设备,有效地降低了设备的工作温度。但空冷技术主要靠空冷风机吹出冷风为凝汽器降温,存在效率低下、维护成本高等缺点。通过搭建凝汽器放热和传热模型,实时计算空冷换热单元的总传热系数,并以特定的业务逻辑部署前后端监控软件,以实现数据的传输、处理与展示。通过海量数据分析得出空冷岛脏污状况与换热单元传热系数、凝汽器背压之间的关联关系,准确判断空冷岛需要清洗的时间,达到节约成本、提升效率的目的。In the northern part of Shanxi Province,which is rich in coal resources but scarce in water resources in China,the winter is cold and lasts for a long time,mainly dominated by northwest winds.The daytime is short and the weather is dry.The direct air cooling technology has successfully replaced the water cooling system to cool the power generation equipment by virtue of its small footprint and the advantage of saving water resources,which effectively reduces the working temperature of the equipment.However,the air cooling technology mainly relies on the air cooling fan to blow out the cold air to cool the condenser,which has the disadvantages of relatively low efficiency,high maintenance cost.By building a condenser heat release and heat transfer model,the total heat transfer coefficient of the air-cooled heat exchange unit is calculated in real time,and the front-end and back-end monitoring software is deployed with specific business logic to realize data transmission,processing and display.Through the analysis of massive data,the correlation between the dirty condition of the air-cooled island and the heat transfer coefficient of the heat exchange unit and the back pressure of the condenser is obtained,so as to accurately determine when it is required to clean the air-cooled island,so as to achieve the purpose of saving cost and improving efficiency.
