【摘要】：为了克服水电站施工期洪水预报方案不足,解决施工期洪水预报工作中存在的一些实际问题,针对水电站施工期的河道特性变化,分析了水电站施工期洪水预报的特定需求,提出水电站施工期洪水预报系统的设计思路和研发目标。总体设计方案包括系统开发及运行环境、设计的基本原则、预报模型配制的技术方案、施工期各阶段到运行期预报方案转换的思路等。系统总体上由数据支撑层、应用层、人机交互层构成。重点介绍了该系统开发的预报方案编制与修正、实时洪水预报等主要应用功能。本系统可针对水电站施工的不同阶段快速建立或调整预报方案;实时洪水预报可人机交互进行,支持增加输入预见期内降雨数据的预报,可为早期的防洪决策提供参考依据。该系统已集成到四川锅浪跷水电站施工期水情自动测报系统投入实际应用,从应用情况来看,该系统运行稳定、实用,达到了预期的研发目标,为开展施工期洪水预报工作提供了有效工具。
[Abstract]:In order to overcome the shortage of flood forecasting scheme during construction of hydropower station and to solve some practical problems existing in flood forecasting during construction period, the river channel characteristics of hydropower station during construction period are changed. This paper analyzes the special demand of flood forecast during construction period of hydropower station, and puts forward the design idea and research and development goal of flood forecasting system during construction period of hydropower station. The overall design scheme includes the system development and operation environment, and the basic principles of design. The technical scheme of forecasting model preparation, the train of thought of changing forecast plan from construction period to operation period, etc. The system is generally composed of data support layer and application layer. The structure of human-computer interaction layer. The forecast scheme of the system development is introduced in detail. The main application functions such as real-time flood forecasting and so on. This system can quickly establish or adjust the forecasting scheme for different stages of hydropower station construction. Real time flood forecasting can be carried out by man-machine interaction, which can increase the forecast of rainfall data in the forecast period. The system has been integrated into practical application of automatic water condition measurement and reporting system in the construction period of Guolangxiao Hydropower Station in Sichuan Province. From the application situation, the system is stable and practical. It has achieved the expected research and development goal and provided an effective tool for flood forecasting during construction period.
