Electrical Machines Two synchronous generators operating in parallel 200 MW and 400 MW respectively. The drooping characteristics of their governors are 4% and 5% from no load to full load. Consider the governors operating at 50Hz on no load. How will the machine share, if the load is 600 MW? None of these 200 MW and 400MW generator 2 gets over load generator 1 gets over load None of these 200 MW and 400MW generator 2 gets over load generator 1 gets over load ANSWER DOWNLOAD EXAMIANS APP
Electrical Machines Two 3-phase AC generators are such that one has twice the linear dimensions of the other. The field windings of each are excited to give identical sinusoidal air-gap flux density waveform. Both have the same number of stator slots and identical winding patterns. The conductor/slot in a big generator is K times that of the smaller one. The value of K to get equal no load voltage at same frequency is 1/4. 4. 8. 1/2. 1/4. 4. 8. 1/2. ANSWER DOWNLOAD EXAMIANS APP
