Examine the diesel power generating station having a maximum generating capacity is 3 MVA@ 0.8 p.f' and maximum demand in MW. Ignore transmission losses. Daily load requirement in percentage of maximum demand is given in following Table: 1-f 2-3 Time in hours Load in % of maximum load Time in hours Load in % of maximum load 12- am 64 60 58 noon- 1-2 2-3 1 pm 99 100 3-4 4-5 # F 56 56 3-4 4-5 100 97 96 5-6 6-7 7-8- v 2 58 64 76 5-6 6-7 7-8 96 93 92 8-9 9-10 87 95 8-9 9-10 92 93 10-11 e.
