Problems solved by technology

Although the current power grid icing degree prediction method has taken the influence of ENSO into consideration, it mainly conducts indiscriminate statistics on the data of a period of time, ignoring the particularity of the ENSO period. Therefore, when analyzing the general characteristics of the icing response in the ENSO period There are still cases where the pertinence is not obvious enough

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0036]The idea of ​​the embodiment of the present invention is: a method for analyzing the response degree of icing during the ENSO period, considering the general characteristics of the icing of transmission lines in each province during the ENSO period and the impact of the intensity of ENSO events on the icing of transmission lines, and establishing a method based on the icing during the ENSO period. Calculation method of ice anomaly and correlation between icing and ENSO intensity, and analysis conclusion of icing response program during ENSO period.

[0037] Such as figure 1 As shown, the analysis method of the embodiment of the present invention includes the following steps.

[0038] (1) Data acquisition. Obtain time-corresponding icing data and ENSO index data, and obtain icing data of each province in the past 20 years, including the maximum numb...

Abstract

The invention discloses an ENSO time icing response degree analyzing method. The method comprises the steps of 1, data acquisition; 2.1, ENSO index data partitioning; 2.2, icing data partitioning; 3, average value calculation; 4.1 maximum icing day number anomaly calculation; 4.2, maximum icing thickness anomaly calculation; 5.1, maximum icing day number and ENSO intensity relevancy calculation; 5.2, maximum icing thickness and ENSO intensity relevancy calculation; 6.1, ENSO time anomaly response condition; 6.2, ENSO time relevancy response condition. The method has the advantages that ENSO time power transmission line icing general characteristics and ENSO event response condition can be learnt comprehensively, operability is high, and power transmission line icing control can be conducted in a more targeted mode.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a method for calculating and analyzing ice-covering response degree in ENSO period. Background technique [0002] With the advancement of the Energy Internet and the construction of cross-regional power grids, the influence of many environmental factors on transmission line corridors has attracted more and more attention. Icing seriously threatens the safe and stable operation of transmission lines. The ice disaster in southern China in 2008 caused more than 1,300 towers of power transmission lines to collapse, property losses exceeded 12 billion yuan, and the Beijing-Guangzhou electrified railway was shut down, posing a serious threat to social stability and people's production and life. The "11.7" ice disaster in Liaoning in 2015 caused 380,000 users to experience power outages, more than 300 trips, and a cumulative power loss of 640,000 kWh. Theref...
