A method for identifying falsification of energy-saving data of energy-saving equipment in power distribution system

Abstract

The invention discloses a method for identifying forgery of energy-saving data of energy-saving equipment in a power distribution system. The method of the present invention includes: collecting the energy-saving data uploaded by the energy-saving equipment of the power distribution system, verifying whether the corresponding relationship of the electrical quantity data is correct, and performing centralized and standardized processing on all voltage and current data; The normal distribution and curve fitting of the current RMS data are extracted as the data eigenvalues, and the time difference between the voltage and current extreme values ​​of the voltage and current waveforms that have been centralized and standardized is extracted as the eigenvalues; the obtained data eigenvalues ​​are expressed as a vector The form is stored as a historical feature value. When a new feature value is generated, the historical feature value is compared with the new feature value to verify the authenticity of the energy saving data. The technical scheme of the invention can effectively realize the anti-counterfeiting identification of energy-saving data, and improve the security of energy-saving verification.

Description

technical field [0001] The invention relates to the technical field of data metering of power distribution and utilization systems, in particular to a method for identifying forgery of energy-saving data of energy-saving equipment in power distribution and utilization systems. Background technique [0002] The rapid development of digitalization and informatization has brought unprecedented convenience to the data collection and analysis of power distribution system. However, virtual data is easily tampered with by humans, and identifying the authenticity of data has become a bottleneck in the development of power distribution system informatization. In the energy-saving field of power distribution system, a large amount of electrical quantity data is required to calculate the energy-saving energy of the system. The general method in the industry to ensure the authenticity of collected data is: use certified meters to collect data and encrypt the collected data. The two leve...
