金昌热电厂空冷气象条件分析

Analysis on Meteorological Conditions of the Air Cooling System for Thermal Power Plants of Jinchang

空冷气象对比观测是空冷电厂勘测设计过程中提供客观反映空冷环境气象条件所必须的技术手段和方法。通过2008年4月1日至2009年3月31日金昌热电厂建设初期在厂址处建立的临时气象观测站资料,和临近气象站——金昌站的观测资料对比分析,通过相关的数学模型重建电厂厂址处近10 a的气象资料,进行分析研究得出电力设计最终所需的各种气象参数和指标。

During the survey and design process of the air - cooling power plant, the comparison of meteorological factors of air - cool- ing was necessary to reflect objectively the meteorological conditions of air - cooling environment. Based on air temperature, wind speed and wind direction in different height at the temporary weather station located in thermal power plant of Jinchang from April 1,2008 to March 31, 2009 and the nearby Jinchang weather station from 1999 to 2009, the contrast analysis of meteorological data was carried out, firstly. Then, the correlations of meteorological factors between the power plant site and Jinchang weather station were studied, and the meteorological data of power plant site at nearly 10 years were reconstructed by regression models. And on this basis, the final meteorological parameters and indicators required by power plant were obtained.
