基于C平台的水力过渡过程计算研究

Research on hydraulic transition process calculation based on platform C

为了准确预测机组过渡过程时的状况,推荐较为合理的导叶关闭时间和规律,以七里塘电站为例,应用基于C程序编制的过渡过程计算程序,结合电站引水系统和机组参数,计算不同工况下的结果,与实际运行时导叶设定的关闭规律和时间对比,结果表明,程序计算结果与实际运行规律很接近,说明该程序应用于计算电站过渡过程是可行的。

In order to accurately predict the condition of the unit during the transition process and recommend a more reasonable closing time and rule of the guide vane,this paper takes the Qili Tang power station which has been in operation as an example to calculate the results under different working conditions by using the transition process calculation program based on C program,combining with the water diversion system and unit parameters of the power station,and then compares the closing rule and time set by the guide vane during actual operation.The results show that the result calculated by the program is very close to the actual operating rule,indicating that the program is feasible to calculate the transition process of the power station,and can also guide the design of other power stations.
