Does anybody know how the automatic load regulator (or load control) systems work? Their function in life is to limit and control the output power of the traction generator/alternator to prevent overloading or stalling the diesel engine. They also impose voltage or current limits on the traction output. I have done a bit of a search on the internet and got some basic descriptions of their basic function, but have nothing about how they do their job.
In the 'good old days' of the 1950s to 1980s they seemed to be a combination of mechanical and/or pneumatic/hydraulic, with various levers, cylinders, actuators etc and, today they all "controlled by computer".
It matters not the implementation, whether mechanical or computerised, the function is the same. What do they do and how do they do it?
Can anybody refer me to any links, of copies of things from their private collection, that describe their operation? Don't bother posting any links that just say "Done by computer" or similar, they have little value.
In general they seem to adjust the electrical output to equal (but not to exceed) the mechanical input, but how do they handle things like moving a light engine in the yard when, even on idle, there is much more power available than is needed just to move the engine? Is the prime throttle the driver moves the diesel engine throttle, or does he request a certain power output, and the system increases diesel engine speed (adjusting the traction parameters) to suit?
Any input appreciated.
