Abstract

A system and method for synchronizing a remote generator to a bus, whether or not power from the bus is available at the generator. The system includes: a first clock at a host site; a host timing processor for determining the time of a synchronizing event; a communication channel for transmitting the time to a remote site; a second clock at a remote site synchronized to the first clock; and a remote timing processor for receiving the time of a synchronizing event, comparing the time of the event to the time of a similar event at the generator, and adjusting the speed of the generator to synchronize the generator to the bus.

Claims

1. A system for synchronizing an electrical generator to a remote bus comprising:

a first timing processor having a first clock, said first timing processor configured to provide time codes corresponding to a fixed point in the waveform of the electricity available on the bus;

a second timing processor having a second clock operating in synchronization with said first clock, said second timing processor configured to receive time codes from said first timing processor and to adjust the output of the electrical generator to synchronize the output with the electricity available on the bus; and

a communication channel between said first timing processor and said second timing processor for the transmission and reception of said time code.

2. The system for synchronizing a generator to a remote bus of claim 1 wherein said first clock and said second clock indicate GPS time.

3. The system for synchronizing a generator to a remote bus of claim 1 wherein said communication channel is the internet.

4. The system for synchronizing a generator to a bus of claim 1 wherein said communication channel is a telephone line.

5. A method for synchronizing a generator to a bus including the steps of:

(a) synchronizing a first clock at a generator with a second clock at a host site;

(b) obtaining the time corresponding to a first fixed point in the waveform of the electricity on the bus from said second clock;

(e) transmitting said time to the generator;

(d) calculating a time when a second fixed point should occur in the waveform of the electricity produced by the generator;

(e) adjusting the speed of the generator such that said second fixed point will occur at the time calculated in step (d).

6. The method for synchronizing a generator to a bus of claim 5 including the further step of:

(f) repeating steps (a)-(e) in a continuous manner.
