如何用 SMPM 和逆变器修复 "Model is not globally balanced"
How to fix "Model is not globally balanced" with SMPM and inverter
基于示例 Modelica.Electrical.Machines.Examples.SynchronousInductionMachines.SMPM_VoltageSource，我正在尝试使用来自 Modelica.Electrical.PowerConverters.DCAC.MultiPhase2Level 的逆变器为 SMPM 供电。
不幸的是我得到了错误
Simulation model is not globally balanced, having 337 variables and
335 equations
但我不知道哪两个方程式丢失了。
更让我困惑的是，如果我删除 signalPWM、inverter 和 constantVoltage 来源，模型是平衡的。

A synchronous induction machine with permanent magnets accelerates a quadratic speed dependent load from standstill.
The rms values of d- and q-current in rotor fixed coordinate system are controlled by the voltageController,
and the output voltages fed to the machine. The result shows that the torque is influenced by the q-current,
whereas the stator voltage is influenced by the d-current.</p>

有人知道如何解决这个问题，这样我就可以制作这个模型了吗运行？
非常感谢任何帮助！
您使用 m=3 个实例对组件 componentsignalPWM 进行了向量化。但只有第一个实例连接了输入。
更改连接
connect(voltageController.y[1], signalPWM[1].dutyCycle)
到
connect(voltageController.y, signalPWM.dutyCycle)
将 voltageController 的三个输出连接到三个 signalPWM 块的输入。

<p>
A synchronous induction machine with permanent magnets accelerates a quadratic speed dependent load from standstill.
The rms values of d- and q-current in rotor fixed coordinate system are controlled by the voltageController,
and the output voltages fed to the machine. The result shows that the torque is influenced by the q-current,
whereas the stator voltage is influenced by the d-current.</p>

Default machine parameters of model <a href=\"modelica://Modelica.Electrical.Machines.BasicMachines.SynchronousInductionMachines.SM_PermanentMagnet\">SM_PermanentMagnet</a> are used.

有人知道如何解决这个问题，这样我就可以制作这个模型了吗运行？
非常感谢任何帮助！
您使用 m=3 个实例对组件 componentsignalPWM 进行了向量化。但只有第一个实例连接了输入。
更改连接
connect(voltageController.y[1], signalPWM[1].dutyCycle)
到
connect(voltageController.y, signalPWM.dutyCycle)
将 voltageController 的三个输出连接到三个 signalPWM 块的输入。
