Method for detecting result credibility of load identification equipment

Abstract

The invention provides a method for detecting the result credibility of load identification equipment, and the method comprises the steps: compiling a corresponding test case for a typical power utilization scene, carrying out wave recording of the power utilization scene for the test case, and recording a load identification parameter of each test case; carrying out weight distribution on each test case; combining various test cases to form a final test scheme; then, according to a case sequence in the test scheme, sequentially restoring the power utilization scene waveform files in the use cases into actual power utilization scenes through a waveform playback instrument, then collecting the identification result of the load identification equipment continuously, and finally analyzing theload identification effect of the load identification equipment in a multi-dimensional mode based on a load identification standard value in the use case library and the actual value given by the load identification equipment; and obtaining a result. A large number of electric appliances do not need to be purchased for a test site, the cost is low, interference of human factors is avoided, errorsof standard values are reduced, the labor cost in the test process is reduced, and a given conclusion is more credible.

Description

technical field [0001] The invention belongs to the field of load identification method detection, in particular to a method for detecting the reliability of load identification equipment results. Background technique [0002] The functions of load identification equipment include data collection, load identification and data upload, and the testing content covers type test testing, general function testing and core identification function testing. The existing detection methods have reference significance for the type test detection and general function detection of non-intrusive terminals, but they cannot be applied to the core function of non-intrusive terminals-load identification capability testing. The currently feasible detection method is to construct a real power consumption scenario to test the load identification capability of the load identification equipment. However, this method has the following obvious deficiencies: First, the power consumption scene is comp...

Problems solved by technology

However, this method has the following obvious deficiencies: First, the power consumption scene is complex and changeable, generally a scene where multiple electrical appliances are superimposed, and the real electrical appliance simulation, the site occupation cost and the cost of funds are relatively high; secondly, the electricity consumption of the electrical appliances As with the measurement of various identification parameters, in the same scene, due to differences in human manipulation, there are also uncertainties, resulting in human error in the identification benchmark value of the test, which cannot be quantified well; again, the control of electrical appliances requires human intervention. To simulate the real electric field, which increases the labor cost in the test process; finally, because the identification benchmark value of the actual power consumption scene cannot be reasonably quantified, the identification result lacks a benchmark value for comparison, and accurate identification accuracy results cannot be given.

Therefore, in short, there is a lack of a reasonable identification ability evaluation system
