Python与PSS/E
我试图使用python程序更改PSS/E中的总线负载。因此，我尝试用python编写一个脚本，可以在PSS/E中的两条总线之间将负载更改为不同的值。 我发现了这篇关于如何从PSSE运行Python命令的博文。不过，我认为你的问题与ASP.NET无关Python与PSS/E,python,psse,Python,Psse,我试图使用python程序更改PSS/E中的总线负载。因此，我尝试用python编写一个脚本，可以在PSS/E中的两条总线之间将负载更改为不同的值。 我发现了这篇关于如何从PSSE运行Python命令的博文。不过，我认为你的问题与ASP.NET无关 我发现了这篇关于如何从PSSE运行Python命令的博文。不过，我认为你的问题与ASP.NET无关 您可以使用名为“LOAD_CHNG_4”的API例程（在API.pdf文档中搜索此路由）。此例程属于负载数据规范函数集。它可用于修改工况中现有荷载的

ierr = psspy.load_chang(bus_number, load_id, intgar,realar)
