A generating station has a maximum demand of 75MW and a yearly load factor of 45%. Annual Generating costs inclusive of station capital costs are 1200 Dinars/kW demand plus 80 Dinars/kWh transmitted. The annual capital charges for transmission system are 40 million Dinars and for distribution system 30 million Dinars ; the respective diversity factors being 1:3 and 1:4. The efficiency of transmission system is 90% and that of the distribution system inclusive of substation losses is 85%. Find the yearly cost per kW demand and cost per kWh supplied : (1) at the substation (2) at the consumers premises.

Transcribed Image Text:A generating station has a maximum
demand of 75MW and a yearly load
factor of 45%. Annual Generating
costs inclusive of station capital
costs are 1200 Dinars/kW demand
plus 80 Dinars/kWh transmitted. The
annual capital charges for
transmission system are 40 million
Dinars and for distribution system 30
million Dinars ; the respective
diversity factors being 1:3 and 1-4. The
efficiency of transmission system is
90% and that of the distribution
system inclusive of substation losses
is 85%. Find the yearly cost per kW
demand and cost per kWh supplied :
(1) at the substation (2) at the
consumers premises.
