Abstract

10kV distribution network is an important part of power system, and its line loss problem is directly related to the economic operation and energy utilization efficiency of power system. Therefore, it is of great significance to study the simulation calculation of the 10kV distribution network line loss to improve the operation efficiency and economic benefit of the power system. The introduction of distributed power supply has an impact on the line loss of the distribution network, so it is necessary to study the mechanism and law of its influence on the line loss to provide theoretical support for reducing the line loss. Matlab The software is widely used in the simulation calculation of power system. By building a mathematical model, it can easily simulate the operation state of the distribution network and the access situation of distributed power supply, providing an effective tool for line loss calculation.

The topic of this paper is based on the simulation calculation of the line loss of 10kV distribution network, studying the actual development status of the current distribution network, analyzing the impact of the introduction of distributed power supply on the line loss of the distribution network, and building a mathematical model through Matlab software to complete the access of distributed power supply, calculate the network loss, propose problems and effective loss reduction measures.

Based on the simulation calculation of line loss of 10kV distribution network, this paper discusses the actual development status of the current distribution network, and introduces the theoretical calculation basis of line loss of distribution network. By analyzing the impact of the introduction of distributed power supply on the distribution network line loss, we establish a mathematical model based on Matlab, simulate the process of distributed power supply access to the distribution network, and calculate the network loss. In view of the problems found, we propose a series of effective loss reduction measures. The main tasks of this paper include establishing a mathematical model of the 10kV distribution network to provide theoretical support and practical guidance for the line loss reduction.
