Why can't the dynamic simulation step time be smaller than 0.03s?

Large time constants may result to the instability of numerical simulation. You must select a time constant that can capture stability phenomena in the range of 0.1 - 10 seconds. Please consult PSS/E PAGV2.pdf manual for more information.

Normal time step is 0.01 s for 50 Hz systems and 0.008333 s for 60 Hz systems. You may have a problem with too short time constants in some dynamic models.
