SYSTEM AND METHOD EMPLOYING A HIERARCHICAL LOAD FEATURE DATABASE TO IDENTIFY ELECTRIC LOAD TYPES OF DIFFERENT ELECTRIC LOADS
First Claim
1. A method of identifying electric load types of a plurality of different electric loads, said method comprising:
- providing a hierarchical load feature database comprising a plurality of layers;
including with each of a plurality of said layers a corresponding load feature set, the corresponding load feature set of at least one of said layers being different from the corresponding load feature set of at least another one of said layers;
including with one of said layers a plurality of different electric load types;
sensing a voltage signal and a current signal for each of said different electric loads;
determining at least four different load features from said sensed voltage signal and said sensed current signal for a corresponding one of said different electric loads; and
identifying by a processor one of said different electric load types by relating the different load features to the hierarchical load feature database.

Abstract
A method identifies electric load types of a plurality of different electric loads. The method includes providing a hierarchical load feature database having a plurality of layers; including with each of a plurality of the layers a corresponding load feature set, the corresponding load feature set of at least one of the layers being different from the corresponding load feature set of at least another one of the layers; including with one of the layers a plurality of different electric load types; sensing a voltage signal and a current signal for each of the different electric loads; determining at least four different load features from the sensed voltage signal and the sensed current signal for a corresponding one of the different electric loads; and identifying by a processor one of the different electric load types by relating the different load features to the hierarchical load feature database.

19. A system comprising:
-
a hierarchical load feature database comprising a plurality of layers, one of said layers including a plurality of different electric load types; a plurality of sensors structured to sense a voltage signal and a current signal for each of a plurality of different electric loads; and a processor structured to; determine at least four different load features from said sensed voltage signal and said sensed current signal for a corresponding one of said different electric loads, and identify one of said different electric load types by relating the different load features to the hierarchical load feature database, wherein each of a plurality of said layers includes a corresponding load feature set, and wherein the corresponding load feature set of at least one of said layers is different from the corresponding load feature set of at least another one of said layers. - View Dependent Claims (20)
