Systems and methods for synchronizing distributed generation systems
First Claim
1. A system for managing an electric power generation and delivery system comprising:
- a plurality of generators configured to provide distributed electric power generation to the electric power generation and delivery system; and
a plurality of intelligent electronic devices (IEDs), each IED of the plurality of IEDs being communicatively coupled with at least one generator of the plurality of generators, wherein each IED of the plurality of IEDs is configured to;
determine that a subset of IEDs of the plurality of IEDs and an associated subset of generators of the plurality of generators while generating electric power have been isolated to a same isolated sub-grid of the electric power generation and delivery system, andcontrol the speed of an associated generator of the subset of generators based on a phase reference signal received from at least one other IED of the subset of IEDs and a common time signal associated with the plurality of IEDs.

Abstract
A system for managing and synchronizing the operation of an electric power generation and delivery system that includes a number of generators configured to provide distributed electric power generation is disclosed. In the disclosed system, a number of intelligent electronic devices coupled with at distributed generators may be utilized to synchronize the operation of the generators with the system when the generators become isolated from the system. In some embodiments, the disclosed intelligent electronic devices may control the speed of isolated generators based on synchronization information received from at least one other intelligent electronic device and a common time signal.

10. A method for managing an electric power generation and delivery system comprising:
-
determining, by a first intelligent electronic device (IED) configured to control the speed of a first generator, that the first IED and the first generator while generating electric power have been isolated to an isolated sub-grid of the electric power generation and delivery system, the isolated sub-grid including a subset of IEDs of a plurality of IEDs of the electric power generation and delivery system; receiving, at the first IED, a phase reference signal from a second IED of the subset of IEDs configured to control the speed of a second generator and a common time signal; and controlling, by the first IED, the speed of the first generator based on the phase reference signal and the common time signal. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
