A 151-13-35) is a device which converts one form of energy to another.(IEC
Generators often form part of a power plant. However, small independent generators (such as domestic solar panels), especially those generating less than 1 MW, should not be tagged as a power plant. This is known as distributed generation.
The generator itself should be tagged, if visible (such as a wind turbine or solar panel). If the generator is contained within a building (such as with a nuclear reactor or hydroelectric turbine), the generator can be tagged as a node, or the smallest building containing the generator can be tagged.
Commonly Used Tags
|generator:source||Power source of the generator|
|generator:method||Method of power generation|
|generator:type||Type of generator|
|generator:plant||When the generator is part of a power plant, use output when it produces output power of the plant or intermediate when it only feeds other generators.|
|name||Given name of the generator|
|generator:output||Nominal maximum output power (rated power) of the generator|
|frequency||The frequency generated by the generator. This should be used if the generator is known to operate at a different frequency from the national transmission grid, for example to supply traction power to a railway.|
How to map
Add a at the centre of the power generator or preferably create an around the boundary of the generator using aerial photography if available. Tag with power=generator and also a name=* and operator=* if known.
See generator:source=* for a complete list of approved values
Method of generation
The tag generator:method=* is used to describe the technical process or method used to convert the energy source into the energy output.
See generator:method=* for a complete list of approved values.
Type of generator
A new attribute is added, generator:type=*. This attribute is intended to define the type of generator among a single source/method. As a concrete example of what a type is, think about of rendering a map of all nuclear reactors of the same type as those used in Fukushima.
See generator:type=* for a complete list of approved values.
Output power rating
The tag generator:output=* can be used to specify the forms of energy generated, and the rating if known. You can simply use yes as a value if the precise numerical rating is unknown.
Power generators can output multiple forms of energy. For example, a boiler will only output hot water, but a combined heat and power plant will typically output hot water and electricity. Add as many values as are relevant.
If the rating of the output is known, add a numerical value followed by the unit. Otherwise simply add 'yes'.
|generator:output:electricity=*||yes / x W / x kW / x MW / x GW|
|generator:output:heat=*||yes / x W / x kW / x MW / x GW|
|generator:output:hot_water=*||yes / x W / x kW / x MW / x GW|
|generator:output:hot_air=*||yes / x W / x kW / x MW / x GW|
|generator:output:cold_water=*||yes / x W / x kW / x MW / x GW|
|generator:output:cold_air=*||yes / x W / x kW / x MW / x GW|
|generator:output:compressed_air=*||yes / x W / x kW / x MW / x GW|
|generator:output:steam=*||yes / x W / x kW / x MW / x GW|
|generator:output:vacuum=*||yes / x W / x kW / x MW / x GW|
|generator:output:biogas=*||yes / x W / x kW / x MW / x GW|
|generator:output:hydrogen=*||yes / x W / x kW / x MW / x GW|
To tag a 15 MW biomass gasification combined-heat-and-power generator use:
|name||biomass generator usual name (see also ref=*)|
|generator:output:electricity||5 MW or yes if unknown|
|generator:output:hot_water||10 MW or yes if unknown|
Or to tag a solar thermal panel use:
|name||thermal solar panel usual name (see also ref=*)|
|generator:output:hot_water||200 kW or yes if unknown|
Or to tag a wind turbine (a modern electricity-generating wind mill):
|height||height=133 - total height including rotor radius (note: some mappers have tagged the height of the center of the rotor instead)|
|rotor:diameter||rotor:diameter=60 - rotor diameter is 60 meters|
|name||modern wind mill usual name (see also ref=*)|
|generator:output:electricity||3 MW or yes if unknown|
