A 151-13-35) is a device that converts one form of energy to another.(IEC
For example: mechanical energy or sun light to electricity.
A power=generator is tagged as a , or even multipolygon , on the generator itself, if visible (wind turbine, gas turbine, single solar panel...), or on the smallest building containing it (nuclear reactor, hydroelectric turbine...). Large photovoltaic power plants may group solar panels blocks in a single multipolygon.
Furthermore, generators should be tagged with frequency=* since they can operate at different frequencies than the common one used on national grids. Indeed, some power plants can fed train transmission lines which often live at different frequency.
Please note that generator:output=* gives the nominal maximum available rating for the given generator. It's the easiest information we can get. Effective rating would be hard to compute or to obtain from power plans operators.
|generator:source||Power source of the generator|
|generator:method||Method of power generation|
|generator:type||Type of generator|
|optional 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||Output power and its rating for the given generator|
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 as explained above. Use power=plant to tag the whole facility.
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|
This tag used to be used to map whole power plants, often as an .
A recent approval process introduced power=plant for such features and make power=generator dedicated to power generators, the devices inside power plants.
Many power=generators currently correspond to power plants instead of hosted generators. It is recommended to carefully replace them with power=plant tag according to your knowledge of the environment.
Don't do mass edit as for preserving the quality of data.
For example 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 - center of rotor is 133 meters above ground|
|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|
