Nothing is going to change. The frequency is controlled at the power plants themselves. I work at a power plant, our frequency correction built in to our local control logic operates whenever the generator rpm moves a few RPM from 3600. I see it operate at 3601 on the high side and 3597 on the low.

Right, but with the grids sharing power between the plants on the grid and the rolling demands, what happens when one plant is more than 10 degrees out of phase with others on the grid?

That is good. We got a heavy baseload due to industry here, it’s bad enough already because the local util Alliant is notorious for their spikes. They’ve already cost many a headache for the area plants - millions over the years in downtime, maintenance, peak load surcharges, etc. They don’t need any more foolishness.

Right! I knew there was some impact, but it was rattling round in the back of my mind. The generator and bearings are somewhat sensitive to being too far out of design frequencies. Something called moments of inertia: harmonics.

Well, my career, or perhaps that is my professional inclination, is based on breaking things, so they can be fixed or redone better the next go round. Good designs are those that are robust. And how does one learn to be robust? By learning to survive and thrive (at least somewhat) upon the injection of disturbance!
