空冷发电厂的设计气温 ,目前在有关设计规程、规范中没有规定选择方法 ,设计时只能根据有关书籍和参考资料进行确定。通过对目前采用的各种方法 (如年平均气温法、60 0 0h法、全年发电量最大法、+5℃以上平均气温法等 )的分析、筛选 ,认为采用 +5℃以上气温法 ,用 50 %的累计频率作为空冷发电厂的设计气温是合理的。 Air-cooled power plant design temperature, the current design rules, norms in the selection of methods is not provided, the design can only be based on the relevant books and reference materials to determine. Through the analysis and screening of various methods (such as the annual average temperature method, the 60 0h method, the annual maximum generation method and the average temperature method above + 5 ℃), it is considered that the temperature method above + 5 ℃ is adopted, It is reasonable to use a cumulative frequency of 50% as the design air temperature of the air-cooled power plant.
