Generator sizing calculation
Notes 10: Conductor sizing & an example
A calculation that is done very often is to convert a per-unit impedance on one base to a per-unit impedance on another base. A common situation when this calculation is required is when the purchasing a new piece of equipment (e.g., transformer, generator) from a manufacturer (e.g., ABB, GE, Toshiba, etc.), that has to be modeled in a system ...

Manufacturer Sizing Calculations: The manufacturer shall submit a generator sizing calculation to verify the generator will start and maintain the connected loads. In addition, the generator shall be oversized by 25% for consideration of future loads. The following list of equipment and steps are provided for the basis of the calculation: Step ...

Jun 17, 2002 · 21.74 Use the 21 amps for sizing the generator. A voltage drop calculation normally does not need to be done if the generator is close to the distribution panel where the loads receive their power, say 25 feet or less. Conductors for loads must be sized for their ampacity, use NEC 310-16 first, then check for voltage drop.

The generator vessel must be large enough to blunt any pressure oscillations and the sheet generation precise enough to ensure uniform fluid velocity over the entire length of the injection slot. The characteristic element of an LSR is the fluid sheet.

Consider the very simple single phase distribution system of Fig. 1. The per unit impedance between the generator and bus 2 is 0.03125, between bus 2 and bus 3 is 0.10, and between bus 3 and bus 4 is 0.025. The load has a per unit impedance of 3.125. The generator voltage is 1.0 per unit. Compute the normal load current in per-unit.

Unless there are many miles of transmission line, the impedance of the utility will be mainly reactance in the generator. This is all the data needed for the utility. From this data, the short-circuit calculation program can be used to calculate impedance (Z), resistance (R), and reactance (X). This data can also be calculated manually.
