Example 1/The daily demands of three consumers are given below: Time 12 midnight to 8 A.M SAM to 2 PM Consumer 1 No load Consumer 2 200 W No load 1000 W 600 W 2 PM to 4 PM 200 W 4 PM to 10 PM 800 W 10 PM to midnight No load No load 200 W Consumer 3 No load 200 W 1200 W No load 200 W Plot the load curve and find 1. Maximum demand of individual consumer 2. Load factor of individual consumer 3. Diversity factor and 4. Load factor of the station Example 2/ The load duration curve for a typical heavy load being served by a combined hydro-steam system may be approximated by a straight line; maximum and minimum loads being 60,000 kW and 20,000 kW respectively. The hydro power available at the time of minimum regulated flow is just sufficient to take a peak load of 50,000 kWh per day. It is observed that it will be economical to pump water from tail race to the reservoir by utilizing the steam power plant during e off-peak periods and thus running the station at 100% load factor. Determine the maximum capacity of each type of plant. Assume the efficiency of steam conversion to be 60%. [(i) 20,000 kW (ii) 40,000 kW]
