Got Permanent Magnet Generator Questions?

M says:

The solar storms that cause concern in operating the power grid is due to the long transmission lines traversing ground with different impedance along the route of the line. Thus the geomagnetic ground currents induced in the earth which result from a solar storm, move from the earth onto the power grid. These currents are very low frequency between 0 and 4 cycles per second. These currents flow through the power companies transformers and may force them into magnetic saturation and cause voltage distortion and harmonics to show up on the grid.

If the geomagnetic ground currents flow through the power company’s generators, a similar set of problems will occur. If you are talking about a home generator that is isolated from the grid, then no this type of generator will not be affected simply because it does not span a long enough portion of the earth to be affected. As for batteries, it is not likely that any battery system would typically be hooked up in a configuration spanning a great enough distance to see these ground currents either. It would depend on how and what they were hooked up to.

I hope this helps,
