How does connecting a 10MW solar plant into the grid work?

We Answered:

Its a similar process to that of paralleling generators onto an electric buss (grid)

The incoming generator (solar system in this case) need to initially have a slightly higher voltage and frequency that that of the buss (grid).

The AC sine waves need to be synchronized and in the same phase rotation before closing the circuit breaker between the generator and buss. A synchro scope and light bulbs are used for detecting when the AC is synced. Light bulbs are connected between the buss and incoming gen on the same phase. When the light dims and goes out the two AC sine wave are synced as there is zero voltage difference between them.

THe circuit break is closed just before the power becomes synced so as to account for the time is takes to close the breaker.

The voltage on the incoming generator is adjusted to control the amperage and power to balance the load so that the incoming generator doesn't take more power than it can handle.

The circuit breaker is also fitted with a reverse power relay to open the breaker if the generator should draw power from the grid rather than power the grid



For inverters there are special grid tie inverters which have the necessary controls to allow them to be synchronized onto a buss.
