Research On Fast Processing Strategy Of Distribution Line Fault Based On Improved Dichotomy

With the introduction of the national strategic policy "13th Five-Year Development Plan" and "Made in China 2025",China’s industrial industry is constantly transforming,and the production model of people-oriented is constantly transforming into an automated,intelligent industrial robot.This means using The demand for electric energy by electric customers is constantly increasing,and the requirements for power quality and reliability are constantly increasing.For the power supply company,the increasing number of electricity customers in the distribution network will increase the related equipment of the distribution network,and its structure and operation mode will become more diverse.When the complex distribution network line fails,the operation and maintenance personnel will find it more difficult to find and repair the fault point.In order to ensure the rapid positioning,search and isolation of distribution network faults,as soon as possible to restore power to non-faulty power customers,improve power supply reliability,and maintain the interests of power customers,operation and maintenance personnel urgently need to find a solution to this critical problemAccording to the structure of the distribution network,the condition of the equipment and the distribution of users,when the line fails,according to the operation and maintenance of the line,the work flow formulated by the,dichotomy"is used to test the power transmission of the faulty line.The line fault point is located to quickly restore power to the non-faulty section.In addition,after the transformation of the distribution network,some switches are equipped with intelligent fault location devices.Combined with the positioning feedback information,the paper proposes a fault location method based on the improved "difference method",and realizes the algorithm by using MATLAB software.Accurately locate faults,improve the fault finding and repair efficiency of the distribution network,and greatly improve the reliability of the power supply of the lineTaking a distribution network line as an example,this paper verifies the feasibility of the fast fault location method based on the improved "difference method",which makes the dispatcher play the role of "commander" in the process of distribution network fault handling.By using the fault rapid positioning method based on the improved "dichotomy",the rationality of the fault handling of the distribution network is ensured,and the power failure time of the distribution network is reduced.For the equipment maintenance department,the application of this method reduces the repair time and avoids that the operation and maintenance personnel spend a lot of time searching for the fault point after the fault occurs,ensuring that they have enough time and energy to invest in the equipment repair and re-operation.Improve the overall fault handling efficiency.
