龙滩水力发电厂水情自动测报系统标准性分析

Standard Analysis of Automatic Water Regime Measuring and Reporting System of Longtan Hydropower Plant

为准确评估龙滩水力发电厂水情自动测报系统雨量站的数据可靠性,充分发挥水情自动测报系统在发电生产的调度指挥作用,以国家基本气象站为标准,运用数理统计方法对比分析红水河流域龙滩水力发电厂水情自动测报系统11个典型雨量站的雨日特征。结果表明,龙滩水力发电厂水情自动测报系统雨量站对日雨量的监测与国家基本气象站点存在相关性和差异性,差异较大的站点则不能参考气象部门雨量预报,应当对该类差异较大的站点进行重新选址或进一步探究二者关联,才能更准确的以气象部门雨量预报为依据进行水库调度。

In order to accurately evaluate the data reliability from the rain station of the automatic water situation measurement and reporting system of Longtan hydropower plant, giving full play- to the dispatching and command function of the automatic water situation measurement and reporting system in the power generation production. This paper is based on the national basic weather stations and compared and analyzed the rain-day characteristics from their 11 typical precipitation station in Longtan hydropower project of the Hongshui river basin. The results show that there are correlation and difference between the rain station of Longtan hydropower plant and the national basic meteorological stations. That means sites with significant difterences could not refer to the meteorological department forecast of rainfall, and these sites shall be to location or to further explore the two associations, which can be more accurate to rainfall forecast meteorological department as the basis for reservoir dispatching.
