Nameplate Total power

The individual loads may be known to have diversity from their nameplate values. If this is the case then the diversity should be included in the estimation of the consumed power. The total load is estimated by adding together the continuous loads, a nominal proportion of the intermittent loads e.g. 30 to 50%, and a small proportion of the standby loads e.g. zero to 10%. The summation shonld be carried out in two parts, the first part for the active power and the second part for the reactive power. This is necessary because not all the loads in a group have the same power factor. Once these two totals are estimated the total volt-amperes can be found and then the cnrrent. 

It may not be necessary to put all the high-voltage consumers in the priority table. The most economical approach is to select enough consumers such that their total nameplate power, when multiphed by a factor (K), is equal to the rated output of one generator when it is operating at its highest ambient temperature in its dirty state . In Table 16.3 this would apply to the group of items numbered approximately 16 to 23, such that the motor control centres are not included. The factor K will therefore need to take account of ... 

The Power Plant There are 17 main tuAmes m Hoover Power plant. The original tuAmes were all replaced through an upgrading program between 1986 and 1993. WiA a rated capacity of 2,991,000 hp, and two station-service units rated at 3500 hp eaA, for a plant total of 2,998,000 hp, Ae plant has a nameplate capacity of 2,074,000 kW. This includes Ae two station-service units, whiA are rated at 2400 kW eaA. 

The net capacity factor of a power plant is the ratio of the actual output of a power plant over a period of time (usually during a year) and its potential output if it had operated at full nameplate capacity the entire time. To calculate the capacity factor, the total amount of energy a plant produced during a period of time should be divided by the amount of energy the plant would have produced at full capacity. Capacity factors vary significantly depending on the type of a plant.
