A 100 MVA 50 Hz turboalternator operates at no load at 3000 r.p.m. A load of 25 MW is suddenly applied to the machine and the steam valves to the turbine commence to open after 0.6 secs due to the time-lag in the governor system. Assuming inertia constant H of 4.5 kW-sec per kVA of generator capacity, calculate the frequency to which the generated voltage drops before the steam flow commences to increase to meet the new load.

Two 60MVA, alternators operate in parallel. The setting of the governor are such that the rise in speed from full load to no load is 2% in one machine and 3% in the other, the characteristics being straight lines in both cases. If each machine is fully loaded when the total load is 120MW, what will be the load on the first machine (with 2% speed regulation) when the total load is reduced to 80MW?

3. One phase of a 3-phase alternator consist of 12 coils in series. Each coil has an rms voltage of 10V induced in it and the coils are arranged in slots so that there is a successive phase displacement of 10 electrical degrees between the emf in each coil an the next. Find by calculation the rms value of the total phase voltage developed by the winding. If the alternator has six pole and is driven at 100 rpm.
