Sketching 'load curve' and 'load duration curve', explain their purposes. Define also 'demand factor' and 'plant-use-factor'.
The loads for certain industries are tabulated below for 24 hours. During load duration and load curve, find power required for 40% of the time of the day. If the capacity of the power plant is 35 MW, find the capacity factor of the power plant:

If the load is supplied by two power plants, one is acting as a base load plant having capacity of 25 MW and other as peak load plant having capacity of 10 MW, find load factor, capacity factor and use factor for both power plants.
