“A generator just like HP checks on train engines.”
Is that something like a load bank/generator combo? I’ve been around generator repair facilities where a generator is hooked up to a load bank where various loads can be applied to check out the generator. Max loads really make the big diesel engine bark, and usually goes to wide open throttle.
Most locomotives have a “load test” mode that connects the main generator to the dynamic braking grids, thus using them as a large load.
The grid resistors are force cooled with a blower, and can usually absorb upwards of 4500~6000 horsepower depending on the model of locomotive.
They are basically a 3 megawatt hair drier.
A 103,000HP engine however, would need at least a 75 megawatt load bank. That’s an insane amount of power to dissipate. I don’t know, hook it up to a steel mill or something.
I work in an electric motor repair facility and we recently hired someone who worked for a railroad. He told me about the generator test but those are built into the locomotive. They do have some sort of a load bank which I'd love to see in action. We load electric motors hydraulically but we are limited to 500 hp and that generated enormous heat right away. I've been studying this particular diesel for quite a while. Given the known efficiency of diesels and the energy content of the fuel oil, they can get a rough idea of HP simply from fuel burn.
All fascinating stuff that's for sure! I read that this Korean diesel is some 50 percent, I think, more efficient than the gas turbines that are also used.
We have a nuke power plant nearby. About 8 of these diesel engines would equal that nuke.
