Embodiment Construction
[0068] The technical solution in this application will be described in further detail below in conjunction with the accompanying drawings.
[0069] Strictly speaking, harmonics refer to the electricity whose frequency contained in the current is an integer multiple of the fundamental wave. Generally, it refers to the Fourier series decomposition of periodic non-sinusoidal electricity. The amount of electricity produced by an electric current.
[0070] For the transportation line and the equipment on the line, harmonics will increase additional loss, cause heat or even overheating, easily cause safety accidents, affect stability and reliability, and increase unnecessary loss.
[0071] The method for tracing the source of the harmonic current disclosed in the embodiment of the present application traces the source of the harmonic through the monitoring and analysis of the harmonic, which helps to find the source of the harmonic and realize the radical cure of the harmonic. It s...

This application relates to a harmonic current traceability method and a long-distance transmission power operation and maintenance monitoring platform. The method includes obtaining address information and sample information of abnormal alarm information belonging to the same unit time; grouping abnormal alarm information according to the address information ;According to the rank sequence, sort the abnormal alarm information in the same group from high to low; analyze the sample information of any two adjacent abnormal alarm information belonging to the same group in the rank sequence, and judge its Degree of similarity; perform secondary grouping of abnormal alarm information whose similarity degree is greater than the similarity judgment threshold; select the abnormal alarm information with the highest rank sequence in the secondary grouping, and record it as special abnormal alarm information; and take the address information of special abnormal alarm information as An alarm message is issued. This application can trace the source of harmonics, which helps to improve the reliability of power grid operation.
