Electrical Engineering XYZ MCQs
In order to have lower cost of power generation:
- The load factor and diversity factor should be high
- The load factor and diversity factor should be low
- Load factor should be low, diversity factor should be high
- Load factor should be high, diversity factor should be low
Correct answer: 1. The load factor and diversity factor should be high
Explanation: In order to have lower cost of power generation, the load factor and diversity factor should be high.
- High Load Factor: Higher the load factor of the power station, lesser* will be the cost per unit generated. It is because higher load factor factor means lesser maximum demand. The station capacity is so selected that it must meet the maximum demand. Now, lower maximum demand means lower capacity of the plant which, therefore, reduces the cost of the plant.
- High Diversity Factor: The greater the diversity factor, the lesser‡ is the cost of generation of power. Greater diversity factor means lesser maximum demand. This in turn means that lesser plant capcity is required. Thus, the capital investment on the plant is reduced.
