Matlab SimPowerSystem simple generator implementation

I want to implement the simple following configuration with Simulink, http://i.stack.imgur.com/39lhT.jpg

For the generator I used Synchronous Machine SI Fundamental from 开发者_如何学Gothe SimPowerSystem Toolbox. For the load I used Three-Phase Series RLC Branch from the SimPowerSystem Toolbox.

If the inductance is zero, the simulation runs. But if the inductance is non zero, I got the error message :

Error using powersys at 16 The following two blocks cannot be connected in series:

Block 1: 'A: Synchronous Machine SI Fundamental'

Block 2: 'phase_A: Three-Phase Series RLC Branch'

I checked in the SimPowerSystem documentation, there is no reference about this problem. Is it an error of implementation ?

Trying with other load blocks, I got the following message :

The first block, modeled as a current source cannot be connected in series with the inductive element of the second block.

I had a high value resistance in parallel with the Three-Phase Series RLC branch, it solved the problem.
