Distribution network operation fault solving method

Abstract

The invention provides a distribution network operation fault solving method. The method comprises the following steps: step (1), strengthening the lightning protection performance; step (2), improving the structure of a distribution network; step (3), improving the adaptability of the distribution network; and step (4), diagnosing non-sound information faults. The distribution network operation fault solving method provided by the invention can reduce the fault loss, reduce the fault probability, and save the maintenance cost, thereby reducing the inconvenience and loss caused by the faults.

Description

technical field [0001] The invention relates to the field of distribution network operation, in particular to a method for solving distribution network operation faults. Background technique [0002] The distribution network is a very important component of the power system. With the development of the country's economy, social electricity consumption continues to increase, and the scale of the distribution network continues to increase. The society's requirements for the stability of power supply are also getting higher and higher. However, the distribution network directly operates in the natural environment, and is affected by various factors, and various faults are unavoidable. How to eliminate faults and restore power supply in the first place has become the most concerned issue for researchers. [0003] Distribution network operation faults mainly include three types: faults caused by distribution operating environment, faults caused by distribution network structural ...

Problems solved by technology

[0004] Faults caused by the power distribution operating environment, including unexpected power outages, unreasonable line distribution, and pollution flashover; unreasonable distribution network structure, including unreasonable distribution of distribution transformer equipment, unreasonable switching and transmission equipment, and problems with relay protection settings; The line loss is too large, mainly due to the high consumption of the distribution network itself

[0005] The power system is gradually developing in the direction of intelligence. The scale of the power system is getting larger and larger, but the number of operation and management personnel is getting smaller and smaller. The degree of automation of the power system is getting higher and higher. Although the operation stability of the smart grid is getting higher and higher, However, the elimination of distribution network faults still depends on the operation and maintenance of equipment based on manpower. It is of great significance to study the solutions to faults in distribution network operation to reduce the loss of faults and the probability of faults.
