AI Thread Summary
Power is imported or exported between states through a unified grid system that allows for the transfer of electricity based on supply and demand. When one state has excess power, it can supply neighboring states, while it can draw power from them when it faces shortages. This process operates under the principles of Ohm's Law, which governs electrical flow. Synchronous machines connected in parallel function together, similar to a team of horses working in harness. The interconnected grid facilitates efficient energy distribution across regions.

How power imported or exported using grids between two or more state??

there is a single grid system throughout the country.. if one state has more power it supplies others through a grid., if the same state is deficient of power it gets power from others by SAME GRID., how is this possible?? wats the principle?? :confused:
 
Engineering news on Phys.org


the principle is ohm's law.

you might read the thread on alternators started by Bassalisk.

Synchronous machines connected in parallel are mechanically coupled by the grid, just as a team of horses is coupled by their harness equipment (is tack correct word?) .
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
