Distributed/decentrallized power generation vs. Regional power generation

AI Thread Summary
The discussion clarifies the terms "distributed" and "decentralized" power generation, noting that distributed generation typically occurs at medium/low voltage levels within a grid, while decentralized generation involves independent, smaller units. Regional power generation is identified as being connected solely to high voltage lines. The conversation also touches on the emerging trend of small modular nuclear reactors designed for local or remote applications, highlighting their potential advantages in specific contexts. Concerns about the cost and complexity of nuclear waste management are raised, questioning whether a single large nuclear facility is more efficient than multiple smaller ones. Overall, the thread emphasizes the evolving landscape of power generation technologies and their implications for energy distribution.

Hello everyone!
Need help with understanding the terms "distributed/decentralized" vs. "regional power generation".
1. Is there any difference between the terms "distributed" and "decentralized" generation (of electricity)?
I thought "distributed" means generation of electricity on units joint in a grid, whereas "decentralized" means generating power on independed small-sized units.

2. Does the term "Regional power generation" exist at all?

Thank you

It is my understanding that distributed generation is done on medium/low voltage levels. That is on a line (radial) with loads connected along the line (before and after the generator(s)). This can cause problems with voltage magnitude and protection of lines, among many other problems.

Regional power generation refers to generation connected (only) to high voltage lines/grid.

But there may be other definitions that is correct.
 
Thank you.
I do not know if I'm asking in the correct thread, but my question mostly relates to nuclear generation. There is such a tendency now that small-sized modular units are designed over the world and they are intended to operate either in local grids or individually (e.g. in off-shore oil rigs, or in remote regions whereto fuel is hard to deliver and nuclear generation becomes competitive).

Please, opinions are welcome!
 
My statement does not differentiate on what type of fuel used in generator.

I'm not familiar with small nuclear units, except at ships/sub. Although they are not "small" they either.

But if the transfer capacity of a tie-line between areas limits the loading in one remote area, then installing a generator unit without upgrading the line might be a effective measure (w.r.t. cost, environment e.g.).

But isn't nuclear waste handling and security very expensive? Thus 1 large station is more effective than 10 small?

Do you have a reference? Especially for offshore nuclear generation?
 
"Small" is just a term. It's used for reactors below 300 MW.

Can't say much about off-shore generation. Just know that such possibilities are being studied.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'What happens if shielded cable has short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
