1. A power management architecture for monitoring power quality events in a power distribution system, said architecture comprising:
- a first data source coupled with at least a portion of said power distribution system, the power distribution system being characterized by at least one power quality parameter, wherein said first data source is operative to determine at least one value of said at least one power quality parameter;
a second data source coupled with said first data source, wherein said second data source is operative to evaluate said at least one power quality parameter value and determine at least one power quality event property, said at least one power quality event property being derived at least indirectly from said at least one power quality parameter value and identifying at least one of the power quality events;
a third data source operative to provide at least one non-power quality property, wherein said at least one non-power quality property is not measured, sampled, or derived from said power distribution system; and
a power quality analysis module coupled with said first data source, said second data source, and said third data source, said power quality analysis module comprising a processor operative to compute power quality information based on said at least one power quality parameter value, said at least one power quality event property, and said at least one non-power quality property.

Abstract
A power quality analysis system includes a combination of at least one of a power quality parameter value, power quality event properties, non-power quality properties, and time properties. The parameter value and other properties is used to create power quality information that is descriptive of power quality events. The power quality information is easily configured and organized based on the desired options in order to make it more understandable and usable.

38. A method for generating power quality information to measure power quality events comprising:
-
measuring at least one power quality parameter value of at least a portion of a power distribution system; receiving at least one non-power quality property and at least one power quality event property, wherein said at least one power quality event property comprises an identification of at least one of the power quality events, further wherein said non-power quality property is not measured, sampled, or derived from said power distribution system; evaluating, with a processor, said at least one power quality parameter value, said at least one of said non-power quality property, and said at least one power quality event property to produce said power quality information; and providing said power quality information. - View Dependent Claims (39, 40, 41, 42)
