Automatic diagnosis or repair for a generator controller
First Claim
1. An apparatus comprising:
- a controller;
a plurality of selectively connected inputs to the controller, the plurality of selectively connected inputs including a first input associated with a generator and a second input associated with a bus; and
wherein the controller is configured to receive a first electrical characteristic from the first input assigned to a first connection and a second electrical characteristic from the second input assigned to a second connection;
wherein the controller is configured to generate a switching signal to internally connect the first input to the second connection or internally connect the second input to the first connection in response to a difference between the first electrical characteristic and the second electrical characteristic exceeding a threshold,wherein the controller is configured to compare a current configuration to a past configuration and initiate a validation operation including the switching signal for at least the generator or the bus associated with the current generator configuration.

Abstract
A set of generators are connected in parallel using an electrical bus. One of the generators includes selectively connected inputs including a first input associated with a generator and a second input associated with the bus. A controller is configured to receive a first electrical characteristic from the first input assigned to a first connection and a second electrical characteristic from the second input assigned to a second connection. The controller is configured to generate a switching signal to assign the first input to the second connection or assign the second input to the first connection in response to a difference between the first electrical characteristic and the second electrical characteristic exceeding a threshold.

6. A method comprising:
-
receiving a first electrical characteristic from a generator; receiving a second electrical characteristic from a first component of a power source; performing a first comparison between the first electrical characteristic and the second electrical characteristic; in response to the comparison between the first electrical characteristic and the second electrical characteristic, initiating a validation operation to compare a current configuration to a past configuration to identify an errant connection associated with the first electrical characteristic; and modifying the errant connection associated with the first electrical characteristic and the first component to internally connect to a second component of the power source. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method comprising:
-
receiving status signals from a plurality of generator controllers; analyzing a status signal from one of the plurality of generator controllers; detecting a configuration change from the status signal; and validating connection accuracy of at least one of the plurality of generator controllers in response to the configuration change; wherein an internal connection for at least one of the plurality of generator controllers is modified based on the validating connection accuracy, comparing a current configuration derived from the status signal to a past configuration stored in memory, wherein the configuration change includes a difference between the current configuration and the past configuration. - View Dependent Claims (17, 18)
