Method of measuring power grid line loss

Abstract

The invention relates to a method of measuring power grid line loss. Analysis and calculation are carried out by combining with actual transportation power of various voltage levels of a power grid, and influences of various voltage levels on the whole power grid line loss are acquired. A new measurement index is proposed based on the line loss and other conventional indexes, and by combining with the conventional indexes, the comprehensive evaluation of the power grid line loss condition is provided.

Description

technical field [0001] The invention belongs to the field of power systems. Line loss is an important comprehensive technical and economic index in the power system. The level of line loss can directly affect the economic benefits of electric power enterprises. The invention specifically relates to an index for measuring power network line loss. Background technique [0002] Line loss can be divided into statistical line loss, theoretical line loss, management line loss, economic line loss and rated line loss. Through the calculation of theoretical line loss, it is possible to know the actual active power and reactive power loss of each component equipment in the power grid, calculate the power loss within a period of time, and find out the weak link in the line loss management of the power grid. [0003] Theoretical calculation of line loss refers to the personnel who are engaged in line loss management. According to the structural parameters and operating parameters of the...

Problems solved by technology

However, when calculating related indicators such as the line loss rate of the entire network, the power supply of the entire network cannot be used to measure the economy of the power grid as a whole. Therefore, this patent proposes a new index for measuring line loss, and forms a more complete system in combination with the inherent method.
