1 概述西枝江上的白盆珠水库是东江流域内,以防洪为主,结合发电的综合利用大型水库,需要合理高效调蓄水量。水库调度就是不断处理和解决来水与用水,各用水部门之间的矛盾,使每一立方水发挥最大的作用。而洪水预报是直接用来进行发电防洪调度的依据,可以增加电站的经济效益及防洪社会效益。因此作好洪水预报是搞好水库调度的基本工作之一。长期以来,白盆珠水库的洪水预报都是采用人工手算来进行预报,从水情收报到作出调洪成果一般需要30min左右,而用编制好的电算软件,由计算机演算则可以大大减少预报作业时间,及时进行多方案的洪水调节,同时还可以运用电脑进行日报表和月报表的编制工作。提高日常工作效率。笔者参加了软件的编制工作,现就洪水预报部份作一些说明。
1 Introduction The Baipenzhu reservoir on the Xijiang River is dominated by flood control in the Dongjiang River Basin. Combined with the large-scale integrated utilization of power generation, it is necessary to adjust the water storage volume rationally and efficiently. Reservoir scheduling is to constantly deal with and solve water and water, the contradiction between the various water departments, so that each cubic water play the greatest role. Flood forecasting is the basis directly used for power generation flood control scheduling, which can increase the economic benefits of flood control and social benefits of flood control. Therefore, flood forecasting is one of the basic tasks to do well in reservoir dispatching. For a long time, the flood forecast of Baipenzhu Reservoir has been forecasted by manual calculation. It takes about 30min to report the flood from the hydrological regime to the flood control. However, with computerized software, it can be greatly reduced Forecast work time, timely flood control of multiple programs, but also can use computers for daily and monthly statements of preparation. Improve daily work efficiency. I participated in the preparation of the software, the flood forecast is now part of some instructions.
