1. Give the comparison of hydro-electric power station and nuclear power station on the basis of the following in a tabular form: a. Space required b. running cost c. location of site d. overall efficiency (4 mks) 2. A generating station has the following daily load cycle: Time (hours) 0-4 4-6 6-8 8 - 16 16 - 20 20 22 22 - 24 Load (MW) 30 40 70 50 80 60 50 a. Draw the load curve and the load duration curve (4 mks) b. Find the maximum demand and the units generated (3 mks) c. Find the average load and the load factor (3 mks) 3. State one advantage of grid system. (1 mk)
