Transfer Power from Customer to the Grid
Transfer Power from Customer to the Grid
(OP)
hi,
In our power Distribution System, the power transfer from central station to step-up transformer to substation and for our home use it transfer to a step-down transformer then supplied to our homes
The if one of the customer want to opposite the direction of power
to be from his home (his special generaor,solar cells, hydro car,..)
here is the question :
How can The Customer do That(supply the Grid) without affect the main power ??

This puts the generator a small fraction of a cycle ahead of the grid and power is supplied back to the grid. An inverter must advance its wave form slightly ahead of the grid in order to transfer power to the grid.
Your utility will have rules for the protection required before they will grant permission to export power.

ahmelsayed, as Bill saied, your utility have rules for work with DG-distributed generation.
any step-down transformer work as step-up transformer, w/o problem.
You must think about decoupling/anty-islanding automation/protection.
RE: Transfer Power from Customer to the Grid
but from the above replies i got some points I'll search about and back.
If can suggest more points in this topic to search about ??

1. Frequency
2. Voltage
3. Power Factor
Controlling these parameters we control power flow in power system.
Usually in distribution system, power reversal is rare (only under extremely low load conditions and) therefore the distributed generation synchronize to grid will help reduce the real power flow from the main grid or substation towards load centre.

Power transfer depends on slight changes in phase angle. Voltage and power factor go sideways. They affect reactive power which is at right angles to real power and has little effect on power transfer. (Except for reactive power transfer.)
