Answer Posted / kj
Answer one is mostly correct. Two other factors are important. 1) the winding type (e.g. 2/3 or 5/8) as this can affect circulating neutral current. 2) phase angle at time of synchronising must be within limits to prevent high currents to pull DGs into synch.
For answer two - load sharing equipment can allow DGs of different ratings to be used in parallel. Frequency is important not RPM. The number of poles in an alternator can vary requiring a different RPM for the same frequency.
Another important factor iis governor response to load changes
