With regard to centralized flow regulation , regulating by changing the power has been people ' s common sense and technical current , it mainly includes change the speed of pump and fan , changing their running number and the combine of the two 对于系统流量的集中调节,采用改变动力的方式已成为人们的共识和技术潮流。改变动力的调节主要有改变泵/风机的转速、改变泵/风机联合运行的台数以及二者的结合。
We accomplished the modeling , calculating and simulating , whose modeling are majored in some equations , calculating by using some algorithms . chapter 4 will research on the marine turbine generator simulating system . on account of the fact that marine turbine generator is simple in real ships , we make such generating system simpler 由于船舶废气透平发电机一般在大型油轮中使用，且船舶多种发电机联合运行的船舶电站仿真器是一种培训型仿真器，主要是操作功能的体现，因此，对船舶废气造平发电机的数学模型仿真作了一些简单化处理。
The main results of this paper are as follows : ( 1 ) the operation chart for individual and associated operation of new and old units , is plotted by using series of multiyears flows and the associated charts is advised to direct the reservoir operation . ( 2 ) on the basis of analysis on the characteristics of hydro - information observation system and flood forecasting system , some key problems in flood operation such as dispatching period of time , decision - making method and so on are studied . ( 3 ) the study and development of flood - dispatching simulation model 论文取得的研究成果如下： ( 1 )采用长系列径流资料，绘制了新老机组单独运行和联合运行调度图，通过对比分析，建议采用联合运行调度图来指导水库运行； ( 2 )在对石泉水库水情测报系统和洪水预报系统的特点进行分析的基础上，研究了洪水调度中的几个关键问题，如调度时段、决策方法等； ( 3 )洪水调度仿真模型研究与开发。
As per optimal operation pattern function with annuals cycle , each decision of annual cycle and corresponding operating factors in the light of observed value of random variable , regression analysis at each time - interval is carried out and then regression equation will be as the operation function to guide cooperating operation for group hydropower station 依据优化调度模型函数，以年为周期，将各年周期的决策值及其相关的运行要素作为随机变量的观测值，逐时段做回归分析，并将其回归方程作为指导水电站群联合运行的调度函数。
