Load factor of a power station is defined as

(average load x maximum demand)172

Load factor of a power station is generally

equal to zero Diversity factor is always

High load factor indicates

total plant capacity is utilised for most of the time

cost of generation per unit power is increased

total plant capacity is utilised for most of the time

total plant capacity is not properly utilised for most of the time

A load curve indicates

average kWh (kW) energy consumption during the period

average power used during the period

average kWh (kW) energy consumption during the period

Annual depreciation as per straight line method, is calculated by

the capital cost minus the salvage value, is divided by the number of years of life

the capital cost divided by number of year of life

the capital cost minus the salvage value, is divided by the number of years of life

increasing a uniform sum of money per annum at stipulated rate of interest

In Hopknison demand rate or two parttariff the demand rate or fixed charges are

dependent upon the maximum demand of the consumer

dependent upon the energy consumed

dependent upon the maximum demand of the consumer

Load curve is useful in deciding the

operating schedule of generating units

Maximum demand on a power plant is

the greatest of all “short time interval averaged” demand during a period

instantaneous maximum value of kVA supplied during a period

Load curve helps in deciding
