I've heard otherwise elsewhere: that grid frequency was initially imprecise, was made precise to enable synchronous electric clocks, and then grid interconnection became feasible. https://en.wikipedia.org/wiki/Telechron#Henry_Warren:_the_Synchronous_Motor_and_the_Master_Clock https://en.wikipedia.org/wiki/Telechron#Henry_Warren:_the_Sy... , for instance.
I can't immediately find a cite for the story that some enterprising electric clock company would give clocks to execs at power companies, then let them get annoyed at large errors and demand stable frequency, but that's surely too good to need a cite, eh?
(edit: initially imprecise)
- X-Istence 13y agoGrid interconnection has always been possible, whether it is precise or not, however if one grid was running faster than the other doing such an interconnect would cause the grids to eventually stabilise somewhere in the middle as the faster grid caused the slower grid to speed up and the slower grid caused the faster grid to slow down. The amount of power wasted is insane though. Bringing new turbines online for example means getting the turbine to run in sync with the current clock cycle within a certain percentage otherwise massive damage can be done as the turbine jumps backwards or forwards when connected to the grid.
