Abstract

The invention discloses a test method and system for a digital electric energy meter. Test data of a standard source is used to generate an original data message and a standard metering result; the total frame number and the changed frame number are preset; according to the type of network abnormity, namely continuous abnormity or random abnormity, the original data message is converted into a continuous test data message or a random test data message; and according to the test data message, the digital electric energy meter to be tested generates a to-be-tested metering result, and the to-be-tested metering result is compared with the standard metering result to complete test for the digital electric energy meter. In the test process, the network environment of the digital electric energy meter is simulated, and the performance of the digital electric energy meter is tested more comprehensively and accurately via quantified accurate control for time characteristic of the message, change of time delay, control for frame loss, control for obstruction and change of quality; and influence of different network abnormity conditions on the performance of the digital electric energy meter is analyzed to analyze the processing mechanism of the digital electric energy meter in a quantified manner.

Description

technical field [0001] The invention relates to the technical field of electric equipment testing, in particular to a testing method and system for a digital electric energy meter. Background technique [0002] With a large number of smart substations put into operation, digital energy meters have been widely used. Although, in theory, the digital energy meter has outstanding advantages, which can effectively improve the accuracy of the substation measurement system and reduce the comprehensive error of the electric energy measurement system. [0003] However, many years of operating experience have shown that digital energy meters also have many shortcomings. For example, the accuracy of digital energy meters depends on the stability of network transmission conditions, and the jitter of network transmission can easily cause performance degradation of digital energy meters. Therefore, it is necessary to carry out comprehensive and in-depth research and testing on the measur...
