Linked (synchronous) generators. Which is a string of paralleled AC generators, need to have individual unit load sharing control devices. A generator lagging in speed will be "dragged" up to 60 Hz by the other generating devices. VARS calculation is needed so windmill farms are computer controlled. Voltage, amperage and Hz alarm and shutdown.
The Pacific Intertie System operting on 500,000 DIRECT CURRENT volts is a three thousand two hundred MEGAwatt transmission line: It's architecture is fascinating.
The point being, the same principle used in th tiniest inverter generator is the same as a DC intertie line. Keep reading :)
The grounding system ("chassis negative") consists of 1,067 cast iron anodes buried in a two-foot trench of petroleum coke, which behaves as an electrode, arranged in a ring of 3,255 m (2.02 mi) circumference at Rice Flats (near Rice, Oregon), which is 10.6 km (6.6 mi) SSE of Celilo. It is connected to the converter station by two aerial 644 mm2 ACSR (aluminum conductor, steel reinforced) conductors, which end at a "dead-end" tower.
Fascinating: Yes/No
