我已经在 OpenModelica 的 ThermoPower 库中工作了一段时间，现在尝试通过首先对 Brayton 和 Rankine Power Cycles 进行建模来构建组合的 Power Cycle。
每次我尝试使用泵时，我总是收到如下错误：
[1] 10:31:00 Translation Error
[ThermoPower.Examples: 2523:70-2523:81]: Variable q_nom not found in scope ThermoPower.Examples.RankineCycle.Models.
[2] 10:31:00 Translation Error
[ThermoPower.Examples: 2531:21-2531:69]: Cyclically dependent constants or parameters found in scope : {q_nom}, {head_nom} (ignore with -d=ignoreCycles).
选择的任何泵都将始终为我的模型声明这些错误。我尝试了许多不同类型的解决方案，但都没有成功。
我尝试使用矢量格式声明泵组件参数的值，即：
q_nom = {1,1,1}。尝试模拟时会弹出相同的错误。我尝试直接单击错误只是为了重定向到 ThermoPower.PowerPlants。在这里，我指向一行代码：
函数 flowCharacteristic = ThermoPower.Functions.PumpCharacteristics.quadraticFlow (q_nom= q_nom, head_nom=head_nom);
在这里，我尝试手动输入 q_nom 和 head_nom 的值，但没有成功。我还尝试在模型顶部复制上面的代码行，试图“重新声明”函数flowCharacteristic。这只会导致错误地重新声明不可声明的类。
我尝试了其他解决方案，但没有成功。
如果您对如何解决此问题有任何建议，请随时在下面留下您的意见！
更新：
这是我已经研究了一段时间的模型的代码。
