:(a) A power station has to supply load as follows:

Times(hrs)	0-6	6-12	12-14	14-18	18-24
Load (MW)	30	90	60	100	50

1. Draw the load curve.
2. Draw the load-duration curve.
3. Give a scheme of suitable generating units to supply the level.
4. Calculate load factor, capacity of the plant and plant capacity factor.
