AI Technical Summary

Problems solved by technology

To date, the only viable technique for integrating data is complex, expensive, labor-intensive, and time-consuming for the user
These techniques also allow for limited data integration and require additional hardware (such as GPS hardware), data cables, and supplemental surveillance equipment attachments

Embodiment Construction

[0031] Referring now to FIG. 1 , an automated data integration monitoring system 100 is shown generally. A utility system 102 having multiple monitoring devices M provides data from each monitoring device M in communication with an automated data alignment system 104 and an automated hierarchical classification system 106 . The data is automatically calibrated in the automated data alignment system 104 according to the present invention, and calibrated data is produced so that it represents the data as it is actually seen by multiple monitoring devices M in the power monitoring system 102 at the same time. Hierarchy classification system 106 automatically understands the hierarchy of monitoring devices that exist in utility system 102 and their relationship to each other.

[0032]Once the data from each monitoring device M is calibrated and the location of each monitoring device is known, the data is said to be in the context 108 . Contextual data 108 may be used by software ...

Abstract

Algorithms that automatically align data from multiple monitoring devices to the same zero crossing at the same point in time. Frequency change data per cycle is received from each monitoring device, and a cross-correlation algorithm is performed to determine a correlation coefficient between the reference monitoring device and another monitoring device. The data of another monitoring device is shifted by one cycle, and another correlation coefficient is calculated by a cross-correlation algorithm. The data of the two monitoring devices are aligned at the point where the maximum correlation coefficient is calculated or at the point where the correlation coefficient exceeds a threshold value. It is also possible to synchronize the clocks of the monitoring devices at the same alignment point.

Description

technical field [0001] The present invention relates generally to utility monitoring systems, and more particularly to automated precise alignment of data, automated determination of power monitoring system hierarchies, and automated integration of data in utility monitoring systems. Background technique [0002] Since the creation of electrical distribution systems in the late 19th century, there has been a need to monitor their operational and electrical characteristics. Being able to collect, analyze and respond to information about the power system can improve safety, minimize equipment wear and tear, reduce obsolescence and ultimately save time and money. To this end, monitoring equipment has been developed to measure and report such information. With the advent of the electronic age, the quality and quantity of data from surveillance equipment has greatly improved, and communication networks and software have been developed to collect, display, and store information. ...
