I haven't researched this yet, but wouldn't a true "smart" grid have wiring for communications as well as power?
- thrtythreeforty 4y agoI want to say there's a lot of powerline communication on the grid, but a lot of that infrastructure can't talk through transformers.
- liketochill 4y agoThere is power line carrier signal used between substations and generators on a line but expensive high voltage wave traps are required and you get about 14bits of bandwidth. The applications I’ve done if your bit drops out and health is still good then you have to disconnect. Transmission lines often run fiber too, but used to still use a whole fiber to transmit 8 bits, or serial at 9600 baud
- thrtythreeforty 4y agoHa, that's hilarious. How do you send serial over fiber? Simple on-off keying? Fiber makes a ton of sense. Non conductive and long range. Surely cheap at utility quantities.
- michaelt 4y agoNot usually, no. I mean, my home is already served by cable for the telephone company, cable for the TV company, and a choice of several cellular connections. Most 'smart grid' stuff doesn't try to reinvent the wheel.
