1. If a DC generator delivers 180W to a load, what is the minimum mechanical power (in watts) needed to drive the generator (assume 80% efficiency)? 2. A 5KW generator has full load efficiency of 90.5 %. Determine the total losses. 3. Discuss the regulation of the compound generator ,its advantages and disadvantages . 4. Explain briefly why the voltage does not drop with increasing load for the compound generator. 5. Explain the different methods of speed control of DC series motors?

Step 1
To find the minimum mechanical power needed to drive the generator, we need to take into account the efficiency of the generator. If the generator delivers 180W to the load, then the input power to the generator must be: Input power = Output power / Show more…

A standby Diesel generator set will have the following loads: Inductive load drawing 50 kVA at 0.8 power factor. Lighting load drawing 20 kVA at 1.0 power factor. At what power factor will the generator operate? 2. Two 3-phase 4160V, 60 Hz alternators are operated in parallel. The total load of the system is 1050 kW at 75% lagging power factor. If alternator A is carrying 700 kW at 80% lagging power factor, determine the kVAR of alternator B.
