Replace 'Gas Conventional' converter for 'Gas Turbine' and 'Gas Steam Plant'

[AlexanderWirtz]

For various reasons, merit order and publication of plant data being the most pressing, we need a 'gas turbine' converter. These two technologies are currently still still lumped one. Gas conventional or 'gas_conv' is converter 23: http://beta.et-engine.com/data/latest/nl/converters/23

@cjlaumans feel free to assign who you think is best suited to do this. @wmeyers also gave this issue some thought.

For now give these plants the same plant data, until @cjlaumans has time to do the required research.

For clarity: both these technologies are 'single cycle' technologies a.o.t. the combined cycle technologies of CCGT and IGCC.

@ChaelKruip has created the extra converter. There is now a Gas Turbine and Gas Conv converter. Gas Conv. needs to be renamed Gas Steam

At the moment the two converters have the same properties. I will do the research some time soon.

Actually I found out with some research yesterday that there are 3 types of plant:

• gas turbine
• gas steam or conventional
• gas combi

Gas combi is a combination of a steam engine and a turbine, but with a very different design then a CCGT plant. Most steam turbines have been retrofitted to be combi plants in Holland. This ups the average efficiency to about 45% instead of 40%.

See http://nl.wikipedia.org/wiki/Combi-centrale

Maybe it is good to make this split properly now. Or we can assume gas steam to be both gas combi and gas conventional.

From my research for the Dutch situation I can say that there is about 200 MW installed capacity of Gas Turbines and that these produce a whopping 0,048 TWh (giving it a capacity factor of 0,03). Therefore I think it is actually good that we split them, because it's a very different type of use then other plants.
