A. High.B. Low.C. Remain same.D. None of the above.Answer: A. High.
Explanation: Cost of power generation increases with decrease in power factor. As that actually reduces the generated active power which reduces the maximum load capacity of the plant.
Important Notes: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.
