Embodiment Construction

[0060] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0061] see figure 1 , based on the identification method of high-incidence areas of distribution network faults based on big data, fuzzy positioning of distribution network faults is carried out, and the power outage loss caused by faults is accurately evaluated; on this basis, distribution network faults are mapped with geographic grids to realize The fault loss value of the geographical grid is quantified cumulatively, and the geographical grid is rendered by the color spot map for prompting, providing accurate and customized auxiliary decision-making support for upgrading, reforming, strengthening special patrols, etc. for dispatching, transportation inspection and other departments.

[0062] In order to use this method effectively, it should b...

Abstract

The invention discloses a distribution network high-fault region identification method. The method comprises the following steps: performing fuzzy identification on distribution network fault positions on the basis of multisource data; based on historical load data and meteorological monitoring data, performing distribution network fault power failure load loss evaluation; performing grid division on a geological view and realizing mapping between faults and geological grids; calculating a fault influence statistical index of each geological grid in a given time period and quantifying fault influences in each grid area; according to each fault influence statistical index, performing coloring so as to generate a fault influence color spot graph; and bringing forward corresponding auxiliary decision-making advice to a high-fault region. According to the invention, power failure loss quantification and fuzzy positioning are performed on vast distribution network faults, the mapping is performed with the geological grids, the fault influences of the geological grids are statistically analyzed, and the fault influence color spot graph is formed, such that refined and customized auxiliary decision-making advance is provided for distribution network scheduling, operation and maintenance.

Description

technical field [0001] The invention relates to a big data-based identification method for high-occurrence areas of distribution network faults, which belongs to the field of distribution network security and reliability analysis. Background technique [0002] In the traditional distribution network fault management work, it is often only for a single fault to be judged, and on this basis, the number of distribution network faults in the regional dimension (province, city, county) and time dimension (year, month, day) is counted. The granularity of these statistical results is relatively coarse, which cannot provide effective auxiliary decision-making for distribution network dispatching and inspection. [0003] The occurrence of a single power grid failure has a certain degree of contingency. However, over a long period of time, the failure rate of the area with a weak distribution network frame or backward operation and maintenance is higher than the average level, and it ...
