Abstract

An electric power system includes multiple components that include a generator, a rectifier and a power management and distribution center. Multiple sensors are configured to provide actual responses relating to each of the components. Multiple simulation models are configured to simulate responses of each of the components, and multiple comparators are configured to compare the actual responses to the simulated responses and provide compared values. A diagnostic module is in communication with the comparators and is configured to determine at least one fault in each of the components.
