Question

06. Define Maximum Demand, Demand Factor, Load Curve, Load Factor, Plant Capacity Factor, Diversity Factor

Answer 1

) Maximum Demand: Maximum amount of electrical energy required by a Consumer during a given periodo 1 The consumers demand cannot eneed its maximum demand for any interval of time. It also decides the type of feeder and fuse. Demand factor : It is defined as the ratio of maximum demand to sum of connected loads. It is always less than t Demand Maximum Demand a factor =- B connected load Load Curre : It is graphical plot of Variation of Laad connected versus time. This plot can be for 24 hrs, weekly or annually depending on the consumer. It is helpful in determining

the peak load time and average load (or load factor) of the consumer and is helpful for determining the time of beak loads and light loads for power system stability. Load Factor: It is defined as the ratio of average load to peak load. It is always less thess orequl to t. Load - Averge load < t factor Peck load Plant Capacity: Also known as rated plant Capacity is the maximum electrical energy or lood, a plant can handle without instability. It is the capacity of production of plant refered to energy provided (units) during a given period.

Plant Capacity factor is defined as the ratio of average annud load to rated folant capacity. This factor defines the operations of the plant during a girens period - Average annud load factor rated plant capacity Capacity =- Maximum load & Load factor. - Plant capacity Diversity factor : It is defined as ratio of sum of individul maximum demand to maximum demand of the group. It is greater than t. - Maximum demand of all factor = connected loads (sum) Maximum demand of the group. Dive
