How to Create a Step Load in Simulink for Frequency Observation?

[commelion]

Hi

Would anyone be able to give me some guidance on creating a step load in Simulink, I need this type of loading to observe frequency (slew rate) when a diesel engine with voltage control drives a asynchronous motor. I have most of the circuit built and am using Sim power systems mat lab v12 2009.

Thanks

I attach a layout of my progress thus far
