The Long distance DC power line substation site are supposed to occupy about 40 acres at each end of the line. Most of that area is covered by one humongous building
to keep the elements off semiconductors. Their main function is to change from Ac to DC voltage and back; a whole lot like grid tie solar and wind inverters.
As an aside; ABB (Allen Bradley family) who up until last year owned the Aurora Inverters (formerly PowerOne and now given to Fimer for some 10's of millions in cash to handle "warranty" claims of previously sold ABB inverters tells a story between the lines. It just so happens that ABB solar inverters are identical in hardware. However they certainly aren't interchangeable for use as either wind or solar because of the computer software commands that cause a solar inverter to require constant current such as from a battery(s) or solar panels; whereas the same inverter hooked to a three phase AC wind turbine generator (or a constant voltage genset or a water turbine AC generator etc.) needs what is known as constant voltage
And as an exercise that is worth a fortune; find a way to simply convert output from any common AC Genset to work with any common grid tie solar inverter and I'd personally give you some 100 dollar bills seeing as how they are the largest denomination now available. There has to be some workable schematic to make a simple 10 KW high impedance circuit and thus controllable current needed for solar inverters WHICH ARE THE ONLY GRID TIE CERTIFIED inverters now available. Small scale wind died about 4 years ago. The reputable name brand Grid Tie manufactures all quit manufacturing the with North American certification. Ask SaskPower who only last year dropped small scale Net Metering wind off the renewables list and inserted Carbon Neutral flare gas in its place.
In summary; from what I know. Keep the smoke withinin electronic components; because all it takes to let it out is one episode of overvoltage or short.
Treat them cool and within design parameters and they last virtually forever..
