A 210 MVA, 50 Hz, turbo-alternator operates at no load at 3000 rpm. A load 75 MW is suddenly applied to the machine and the steam valves to the turbine com- mence to open after 1 second due to time lag in the governor system. Assuming inertia constant H = 5 kW-sec/kVA, calculate the frequency to which gener- ated voltage drops, before the steam flow commences to increase to meet the new load.
