我正在尝试使用外部包ModPowerSystems来模拟自定义模型，并使用OMPython来做一些自动化。
我的代码是:from OMPython import OMCSessionZMQ
from OMPython import ModelicaSystem
from pathlib import Path
omc = OMCSessionZMQ()
source_path = Path(__file__).resolve()
source_dir = source_path.parent
mod=ModelicaSystem(str(source_dir)+"/simulator/ModPowerSystems/package.mo",
"ModPowerSystems.CustomModule.Examples.BasicGrids.MainModel",
["ModPowerSystems","Modelica","ModPowerSystems.CustomModule.Loads.DependentModel1","ModPowerSystems.CustomModule.Generation.DependentModel2"])
mod.buildModel()
但是当我运行它时，我得到:

我对openmodelica非常陌生，所以我不确定这里缺少什么。有什么建议吗?

不确定这里发生了什么，但是无法实例化PACKAGE"错误消失了。平坦化模型时出现的误差意味着什么?
更新2:最后一个错误是由于使用了"time"@adrian-pop
指出modelica中不允许的命名组件您似乎有一个名为"time"在MainModel中。在第12行?
旧答案如下(问题已更改)。
有几个问题。如果你加载包。整个库将被加载，所以你不需要在库列表中再次给出它。另外，如果你在库列表中给出了库ModPowerSystems，你不应该在列表中给出任何其他内部包ModPowerSystems. x.y。
代码应该是这样的:
mod=ModelicaSystem(str(source_dir)+"/simulator/ModPowerSystems/package.mo",
"ModPowerSystems.CustomModule.Examples.BasicGrids.MainModel",
["Modelica"])
另一个问题是"Error: Cannot instantiate ModPowerSystems.CustomModule.Examples.BasicGrids.MainModel due to class specialization PACKAGE"。这意味着您试图模拟的类:ModPowerSystems.CustomModule.Examples.BasicGrids.MainModel不是一个模型，而是一个不能模拟的包。也许包中有你需要选择的模型。
还有其他问题，比如包中缺少名称。命令库中的文件，但这些只是警告，我们现在忽略它们。
