OMPython 使用带有外部包的自定义模型

Question

我正在尝试使用外部包 ModPowerSystems 模拟自定义模型，并使用 OMPython 进行一些自动化。

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，我得到了：

我是 openmodelica 的超级新手，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“无法实例化 PACKAGE”错误消失了。扁平化模型时发生的错误是什么意思？

更新 2：

最后一个错误是由于使用了@adrian-pop指出的modelica中不允许的“时间”命名组件

Answer 1

在第 12 行的 MainModel.mo 中似乎有一个名为“time”的组件？

下面的旧答案（问题已更改）。

有几个问题。如果您加载 package.mo 整个库将被加载，因此您无需在库列表中再次提供它。此外，如果您在库列表中提供库 ModPowerSystems，则不应在列表中提供任何其他内部包 ModPowerSystems.X.Y。

代码应如下所示：

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"。这意味着您要模拟的类：ModPowerSystems.CustomModule.Examples.BasicGrids.MainModel 不是模型，是无法模拟的包。也许您需要选择该包中的模型。

还有其他问题，例如库中的 package.order 文件中缺少名称，但这些只是警告，让我们暂时忽略它们。
