Research And Application On Theoretical Line Loss Analysis Method In Distribution Network

The electricity is an important part of the national economy, and is the important power of the social economy development. Reduce the energy losses is an important index of building a first-class of power supply enterprises, but also an important means of a power supply enterprises to improve the economic benefit. Reduce the energy losses is proceeded by the management of energy losses, according to the theoretic calculation results of the line loss, carries on the line loss analysis, find out the power of line loss caused by the reasons of high, by lowering the line loss, the technical measures and management measures, transforming power grid structure, optimize voltage and reactive power management, reasonable arrangement of main transformer the operation mode, accomplish the purpose of reducing loss.This paper based on YanLing grid, adopt tide method, electricity resistance method respectively in 2010 in October of high voltage distribution network, medium voltage distribution network, analyzes the theoretical loss calculation YanLing grid existence and the weak link, and puts forward the measures to decrease the line loss, this paper introduces YanLing grid decrease the line loss of technical measures and management measures.
