What kind of signal does the contr-current source need in a Phasor-Simulation?

Hi,

I'm working with SimPowerSystems.

I have a linear circuit with a controlled current source. I'm using the phasor simulation.

The basic idea of my controlled current source is that it produces a current that is calculated from a an active and reactive power. I split the act. and react. powers in equivalent real and imaginary current parts. THen they are converted with the "Real-Imag to Complex" Block to the complex data typ. This signal feeds the controlled current source.

*Now the Help Doc for the contr-current Source says the input signal of the source needs to be a complex phasor if phasor simulation is activated.

However, the source doesn't accept the complex double data type...*

The error message says: powergui/EquivalentModel1/Sources/Mux expects a signal of numeric type real. However, it is driven by a signal of numeric type complex.

....HELP!! I have no idea reight now!

Below you can see the error Message Matlab generates:

??? Error using ==> Regelkreis_erweitert_Init_and_Control at 102 --> Complex signal mismatch. Input port 2 of 'Regelkreis_Sothel_erweitert/Trafo Kabel Netz1/powergui/EquivalentModel1/Sources/Mux' expects a signal of numeric type real.

Hi stephan

i am gettting same error. could you plz let me knw the solution without updating software. is there any technical issue contain with model?

[efrain]

I have the same problem, I´m using Matlab 2013a..some solution? Thanks.
