Power Monitoring and Analysis System for Identifying and Tracking Individual Electrical Devices

The invention is a method for measuring and processing a plurality of electrical parameters of a common alternating current (AC) service that supplies multiple different electrical devices such that the power use rate and total power used by each of multiple devices is determined. Sensors provide high resolution signals corresponding to the current and voltage of the AC power supplied to the service panel typical of those used in residential construction. Analog-to-digital conversion and processing circuits determine multiple electrical parameters with high resolution at a sampling rate sufficient to determine the electrical parameters for approximately each AC cycle. The electrical parameters are stored as a large data set in a memory with sufficient capacity to store several months of electrical parameters representing each AC cycle. The data set is processed to extract complete on-off cycles of the devices. The on-off cycles are represented by instance structures. The characteristics of the instance structures are used to determine device structures. Each device structure characterizes one of the multiple devices. The contributions associated with the extracted instance structures are subtracted from the data set, making is possible to extract additional instance structures from the residual information in the data set. Information from the device structures are used to help extract instances structures that are partially obscured by overlapping instance structures. The newly extracted instances structures are subtracted from the data set and processing continues until no more instance structures can be extracted. Information from the extracted instance structures and device structures are further grouped and processed to provide useful information reports to a consumer. As the electrical parameters are determined and added to the data set, they can be incrementally processed so that near real time information can be provided to the consumer. The cost of operating each device and other information enables the consumer to make informed decision regarding energy use and conservation.

Automated hierarchy classification in utility monitoring systems

An auto-learned hierarchy algorithm that learns the hierarchical layout of a power monitoring system. Historical power data from each meter is received and placed into a data table. The main is assumed to be at the top of the hierarchy and is designated as the reference. A check matrix is developed indicating whether a possible connection exists between each meter pair combination. A correlation coefficient matrix (CCM) is calculated based on the data table, and entries in which no connection is possible are zeroed. The column for the reference meter from the CCM is copied to a correlation reference array (CRA), and the meter having the highest correlation with the reference meter in the CRA is marked as connected to the reference meter in a connection table. That meter's power is subtracted from the data table and the procedure is repeated until all meters have been analyzed.
