Distribution decision-making method of lightning monitoring device of power distribution network

Abstract

The invention discloses a distribution decision-making method of a lightning monitoring device of a power distribution network. On the basis of a distribution network lightning location system (LLS),a distribution network fault management system and a distribution network GIS system, an integrated cloud-to-ground lightning density analysis map including a distribution network line and an integrated lightning current amplitude analysis map are drawn by considering thunder-and-lightning and cloud-to-ground lightning density distribution, lightning current amplitude data and historical thunder fault rate of a distribution network line comprehensively; a quantitative analysis is carried out on the monitoring device installation priority based on an analytic hierarchy process; and then a distribution network lightning monitoring device distribution plan is determined by combining actual working conditions. According to the invention, the method has the following advantages: a simple and effective lightning monitoring device distribution plan decision-making method is provided by considering various factors comprehensively and using the analytic hierarchy process; the instructional advice is provided for the lightning monitoring work of the distribution network; the method can match most of existing power supply management systems and has the great practical application value; and the effectiveness and economy of the lightning protection work of the distribution network are improved.

Description

technical field [0001] The invention belongs to the lightning protection monitoring technology of a distribution network system, and in particular relates to a decision-making method for distribution network lightning monitoring devices. Background technique [0002] The power industry is an important pillar of the national economy, and as the capillaries of the power system, the distribution network plays a pivotal role in the power system of China. With the rapid construction and development of the power grid and the continuous improvement of the load side's requirements for power supply quality, the construction of a safe, stable, efficient and reliable distribution network has been put on the agenda. [0003] The distribution network system undertakes the task of directly supplying power to users or distributing electric energy to the next-level system. It is characterized by multiple voltage levels, complex network structure, various types of equipment, and a poor safe ...
