when I run this model i got an error
The following two blocks cannot be connected in series: Block 1: 'A_stator: Asynchronous Machine SI Units' Block 2: 'transfo_1_winding_2: 25 kV// 575 V 6*1.75MVA' The first block, modeled as a current source, cannot be connected in series with the inductive element of the second block. Add a high-value resistance in parallel with one of the two block. You can also specify high-value resistive snubbers if the blocks have a snubber device.You can avoid the use of the snubber by selecting the 'Continuous' simulation type in the Solver tab of the Powergui and deselecting the 'Disable ideal switching' option in the Preferences tab of Powergui block.
any one have soultion for this ??

Hi Ahmad,
In Simulink, the asynchronous machine block is implemented as a current source. Thus, in order to connect it with an inductive element such as a Three-Phase AC Source or a transformer you need to connect a “Three-phase RLC Load” in parallel with either of these two blocks.
This will allow you to establish a physical connection between the two in your Simulink Model.
Please refer to the following Snapshot to get a deeper understanding of the workaround.
