Generator modelling

In eCalc™, the term generator refers to equipment producing electrical power from fuel. Hence, the turbine part (fuel combustion to produce mechanical energy) is included in the term.

An installation usually have one or more generators to fill the electrical power demand. In eCalc™, the separate generators are combined into a common generator set (genset).

note

In the future, eCalc™ will most likely offer modelling of single generators that could be combined in systems.

ELECTRICITY2FUEL

Electricity to fuel is a table specifying the relationship between electrical load and fuel consumption for an entire generator set. This means that if you have several generators, this table needs to include a "jump" every time a new generator is started. An example of this is shown below.

Under FACILITY_INPUTS, this electricity to fuel table is specified using the keyword ELECTRICITY2FUEL

Facility input format

FACILITY_INPUTS:
  - NAME: <generator name>
    FILE: <file path to .csv file>
    TYPE: ELECTRICITY2FUEL

Example table

The table for this curve would look like:

POWER, FUEL
#[MW], [Sm3/day]
0.00,  0.0
0.10,  84000.0
5.00,  84000.0
42.0,  220000.0
42.01, 280000.0
45.0,  300000.0
50.0,  330000.0
60.0,  350000.0
