Example Embodiment

[0080] Example:

[0081] The frequent occurrence of power distribution line failures in Xx County, Xx City, has a certain impact on the production and life of the people. xx County Power Company in xx City conducts comprehensive prevention and control of 10kV distribution line faults in accordance with the "Comprehensive Prevention and Control Method for Rural Network Distribution Line Faults".

[0082] The first step is to analyze the cause of the failure and determine the failure rule. According to the fault records of 10kV distribution lines in this area, the causes of line faults in this area are analyzed, and the distribution law of distribution line faults in this area is determined.

[0083] The reasons for the failure of the 10kV line in the distribution network in X County are as follows figure 1 As shown in the figure, the main reasons for the failure in county x are aging equipment and strong wind. The time domain distribution law of 10kV line faults in x count...

Abstract

The invention relates to a comprehensive prevention and control method for rural power grid distribution line fault. The method comprises the following steps: step 1, analyzing line fault causes, and determining distribution rules of the rural power grid distribution line fault; step 2, managing the shortcomings of the rural power grid distribution lines according to line fault geographical distribution rules; and step 3, upgrading and improving the rural power grid distribution lines according to the line fault geographical distribution rules. The comprehensive prevention and control method, by combining power network planning and related conclusions of power grid development diagnosis, designs a whole set of comprehensive prevention and control method for the distribution line fault of the rural power grid on the basis of analyzing rural power grid distribution line fault causes and investment capacity, for guiding the operation and maintenance of the rural power grid distribution line, effectively preventing distribution line faults and feasibly ensuring reliable operation of the rural power grid distribution line.

Description

technical field [0001] The invention relates to the field of operation and maintenance of power distribution lines in rural power grids, in particular to a defect control method and fault prevention measures for power distribution lines in rural power grids—a method for comprehensive prevention and control of power distribution line faults in rural power grids. Background technique [0002] The power supply scope of State Grid Hebei Electric Power Company covers six cities including Shijiazhuang, Handan, Baoding, Xingtai, Cangzhou and Hengshui. It has 1,156 township (town) power supply stations under its jurisdiction and undertakes the power supply task of 31,733 administrative villages in southern Hebei with a population of 49.86 million. . At present, there are frequent faults in the distribution lines of the rural power grid, and the grassroots operation management personnel and production technicians have a heavy workload for emergency repairs, especially in bad weather....
