Abstract

The invention discloses a method for determining smallest sampling sample capacity on the basis of the radio interference value sample data. The method comprises steps that the actually-measured radio interference value sample data is utilized to determine annual smallest radio interference value sampling sample capacity, monthly smallest radio interference value sampling sample capacity and everyday smallest radio interference value sampling sample capacity respectively; radio interference values are sampled according to the annual smallest sampling sample capacity, and the acquired radio interference values are averaged to acquire an average whole year radio interference value; radio interference values are sampled according to the monthly smallest sampling sample capacity, and the acquired radio interference values are averaged to acquire an average whole month radio interference value; radio interference values are sampled according to the everyday smallest sampling sample capacity, and the acquired radio interference values are averaged to acquire an average whole day radio interference value.

Description

technical field [0001] The present invention relates to the field of electromagnetic environment monitoring, and more specifically, to a method and system for determining a minimum sample amount based on sample data of radio interference values. Background technique [0002] The radio interference generated by the corona discharge of high-voltage AC transmission lines is one of the important indicators of electromagnetic environment evaluation. The radio interference level of a line is a complex problem with statistical characteristics. A large amount of measured data at home and abroad in the past shows that the radio interference level of the line under certain conditions has strong random fluctuations and lacks obvious statistical laws. [0003] J.J.LAFOREST and others summarized the research results of Project EHV on radio interference in the past three years, and obtained the histogram and regression analysis of radio interference levels of high-voltage transmission li...
