Title:
METHOD FOR TESTING TASK EXECUTION CAPABILITY OF ELECTRICAL ENERGY METER, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/215748
Kind Code:
A1
Abstract:
A method for testing a task execution capability of an electrical energy meter, and a device. The method comprises: expanding, according to the types and times of task execution of electrical energy meters under test and in a time domain, task execution data of each of the electrical energy meters, and obtaining time-domain expansion sample data of each of the electrical energy meters under test (101); constructing an original data matrix according to the time-domain expansion sample data of all of the electrical energy meters under test, and determining a covariance matrix corresponding to the original data matrix (102); determining an eigenvalue of the covariance matrix and a corresponding eigenvector matrix (103); selecting, according to the number of principal components, a pre-determined number of eigenvectors from the eigenvector matrix, and forming a truncated eigenvector matrix; determining a principal component matrix according to the truncated eigenvector matrix and the original data matrix (104); and testing, according to the principal component matrix, a task execution capability of each of the electrical energy meters under test (105).
