Network equipment statistics and calculation method of network loss based on online theoretical network loss calculation

Abstract

The invention belongs to the technical field of analysis and computation of transmission losses of the power grid in the electric system and particularly relates to a method for counting equipment of the power grid and computing transmission losses on the basis of on-line theoretical transmission loss computation. The method includes: building gate circuits or gate transformers at the boundary of a domination area of a power grid company, automatically counting and updating circuits and transformers involved in the on-line theoretical transmission loss computation on the basis of the topological structure of the power grid, and accordingly, computing distribution of theoretical transmission losses and computing policy for reducing losses. By the method, all equipment involved in transmission loss computation can be automatically determined by manually maintaining the gate circuits and the transformers at the boundary of the domination area of the power grid company only. Besides, when the method is compared with the conventional manner of manual maintenance, work load is greatly reduced, the method can adapt to change of the power grid structure automatically, and availability and accuracy of on-line theoretical transmission loss computation and loss reduction policies for the power grid are improved.

Description

technical field

[0001] The invention belongs to the technical field of grid network loss analysis and calculation in electric power systems, and in particular relates to a loss reduction calculation method for automatically determining equipment participating in statistics in online theoretical network loss calculation of power grids. Background technique

[0002] Electric energy is a secondary energy obtained from primary energy conversion, which can be converted into mechanical energy, thermal energy, magnetic energy, etc. With the development of society, electric energy has become the lifeblood of the development of the national economy, and its application has penetrated into various fields of production and life. With the rapid increase of power transmission in the power grid, the active power loss of the power grid (hereinafter referred to as network loss) also increases significantly. Taking 2007 as an example, China's annual power generation was about 3.3 trillion k...
