黑河引水系统可供水量动态仿真研究

Dynamic simulation on available water supply in Heihe river waterworks

可供水量的计算有多个前提条件,传统概念下的可供水量一般是在某一固定条件下计算出来的,对计算条件的变化考虑不足,致使计算的可供水量与实际情况存在较大差异,难以满足动态变化的应用需求。本文在现有可供水量计算的基础上,考虑不同来水、不同灌溉需水、不同生态需水、不同引水及其相互组合的情况,提出并建立了可供水量动态计算模式,并以黑河引水系统为例,采用知识图、组件等技术,研发了黑河引水系统可供水量动态仿真系统。实例应用结果表明:仿真系统能够对不同计算条件下的黑河引水系统可供水量进行动态计算,从而更好地满足不同应用需求下的可供水量计算与决策需求。动态计算模式及仿真系统可操作性好、适应性强,方便应用推广。

The calculation of available der the traditional concept is generally water supply has a number of preconditions. The water supply uncalculated under a certain condition, the change of calculation conditions is insufficiently considered. As a result, there is a big difference between the calculation of water supply and the actual situation, it is difficult to meet the requirements of the application of the dynamic changes. This paper built a dynamic calculation mode to overcome the problems. The mode combined some situations such as different dispatching water, irrigation demand, ecological demand, water diversion flow and so on. Taking Heihe water diversion system as an example, the paper developed the dynamic simulation system of water supply of Heihe water diversion system by using the technology of knowledge map and components. Application results show that the simulation system can carry on dynamic calculation for water supply under the different calculation conditions of Heihe River water diversion system, so as to better meet the water volume calculation and decision - making needs under different application requirements. The dynamic calculation mode and simulation system has good operation, strong adaptability and convenient application.
