How do I multiplex 3 phase power system signals onto a single signal or generate a varying frequency voltage source

So I am trying to test a HVDC model's response to a frequency deviation. I designed a quick model to output a balanced three phase voltage whose frequency profile I could control (see image attached). The trouble is that I get the voltage as three separate signals, but I need them as a single line. I've tried both generic muxes and physical signal converters, but they don't connect (wrong signal type). Essentially what I want to do is the reverse of a phase splitter block but I can't find a block that will do this.
Please reply if you have a solution to this problem or if you know of a different way to vary the frequency of a three phase voltage source.

Hello Ciaran,
the specialized power systems (specialized technology/simpowersystems) blocks do not support single line wiring. You would have to switch to using simscape blocks if you want a three phase line represented as a single phase line. However, you have implemented the variable frequency voltage source correctly. Using the integrator to drive sin waves is the correct solution.
Regards,
Joel
