Communication failure handling
First Claim
1. A method comprising:
- identifying a disconnection of a first power source from a generator controller of an engine generator set, wherein the generator controller is connected to an alternator and connected to an engine of the engine generator set;
generating a power failure message indicative of the disconnection of the first power source from the generator controller; and
transmitting the power failure message indicative of the disconnection of the first power source from the generator controller of the engine generator set using a second power source, wherein the second power source is switched to power the generator controller in response to the disconnection of the first power source.

Abstract
An electrical power generator system may include two or more paralleled generators. At least one of the generators includes a first power source and a second power source. A disconnection of a first power source is identified at a generator controller of one of the generators. The generator controller may be configured to access or generate a power failure message indicative of the disconnection of the first power source. The generator controller may be configured to transmit the power failure message using the second power source because the second power source is switched to the generator controller in response to the disconnection of the first power source. The system may enter a communication failure handling mode based on the power failure message.

16. A method comprising:
-
establishing communication between a first engine generator set and a second engine generator set, wherein the first engine generator and the second engine generator set are configured to be connected in parallel to provide power to a common load; receiving, at the first engine generator set, a power failure message indicative of a power failure from a generator controller of the second engine generator set wherein the generator controller is connected to an alternator and connected to an engine; and modifying a failure response algorithm of the first engine generator set in response to the power failure message from the second engine generator set. - View Dependent Claims (17, 18, 19)

20. An apparatus comprising:
-
a generator controller configured to operate an engine generator set wherein the generator controller is connected to an alternator and connected to an engine of the engine generator set; a secondary power source for the generator controller; a memory including a power disconnection message; and a switching unit configured to switch the generator controller from a primary power source to the secondary power source in response to a failure of the primary power source, wherein the generator controller accesses the power disconnection message from the memory in response to being switched to the secondary power source.
