Power Station |
 |
|
Connected Load : The sum of the continuous power ratings of the load-consuming apparatus connected to a
generating system.
|
Maximum Demand : The greatest demand of load on the power station during a period is known as maximum demand.
Maximum demand meter is used to measure the maximum demand in power stations. It indicates maximum loading current over
a period.
|
Demand Factor : The ratio of the maximum demand on the power station to the total connected load.
|
Average Load : The average of loads taking place on the power station in a given period.
|
Load Factor : The ratio of average load of a power plant compared to the maximum demand during a given period.
|
Diversity Factor : The ratio of the sum of individual maximum demands compared to the maximum demand on power
station.
|
Plant Use Factor : The ratio of kWh generated to the product of plant capacity and the number of hours for which
the plant remains in operation.
|
Load Curve : The graph that plots load on the power station with reference to time.
|
Load Duration Curve : The graph that is obtained when the load elements of a load are arranged in order of
descending magnitudes. It shows the capacity utilization requirements for each increment of load.
It illustrates the relationship between generating capacity requirements and capacity utilization.
|
Dump Power : It is generated by a source which is in excess of the needs of the electric system and which
cannot be stored or conserved.
|
Firm Power : The power that is always available even under emergency conditions.
|
Prime Power : The maximum potential power that is constantly available for transformation into electric power.
|
Cold Reserve : The reserve generating capacity available for service but not in operation.
|
Hot Reserve : The reserve generating capacity available in operation but not in service.
|
Base Load : The unvarying load occurs almost the whole day on power station. In other words,
The minimum amount of power that a utility or distribution company must make available to its customers.
|
Peak Load : The maximum load or the maximum average load over a designated interval of time.
|
Tariff : The rate at which electrical energy is supplied to a customer.
