A. High.B. Low.C. Remain same.D. Depend upon plant type.Answer: B. Low.
Explanation: Load Factor:- The load factor is the ratio of the average load power to the maximum demand in a specific period of time.
- It can also be defined as the ratio of the total energy used over a specific period of time (KWh) to the total possible energy available within that period (i.e., Maximum demand over that period)
- Load factor value is between 0 and 1.
- The high value of the load factor means the load is using electrical energy more efficiently.
- Hence, the high load factor gives more savings of electrical energy, which means the cost of power generation will be lower.
Diversity factor:- It is defined as the ratio of the sum of the maximum demand of individual loads of the system to the maximum demand of the system itself.
- The diversity factor is always greater than 1.
- By increasing the individual peak loads, the diversity factor will be increased.
- The load is using electrical energy more efficiently and the system efficiency also increases.
- So, the cost of power generation also decreased because of increasing power generation.
- Hence, the Load factor and the Diversity factor values should be high to lower the cost of power generation.
Important Points- The load factor may be the daily load factor, monthly or annually if the period considered is a day or month, or year.
- The load factor is always less than 1 because the average load is smaller than the maximum demand.
- It plays a key role in determining the overall cost per unit generated.
- The higher the load factor of the power station, the lesser will be the cost per unit generated, is because a higher load factor means lesser maximum demand.
- The station capacity is so selected that it must meet the maximum demand.
- Now, lower maximum demand means a lower capacity of the plant which reduces the cost of the plant.
- The greater the diversity factor, the lesser is the cost of generation of power. Because greater diversity factor means lesser maximum demand. Now, lower maximum demand means a lower capacity of the plant which reduces the cost of the plant.
