Abstract

The invention discloses a comprehensive loss reduction and energy-saving calculation analysis method and system for a distribution line and a transformer. The method comprises the steps of distribution line and transformer loss information collection and data verification, line loss modeling, theoretical line loss calculation and loss reduction and energy-saving analysis. The system comprises a service basic module, a power grid model management module, a data center, a theoretical online calculation module, a line loss theoretical calculation analysis module and a loss reduction auxiliary decision module. According to the invention, the distribution network equipment is used to measure the current value and the equipment parameter information of the head end in real time; theoretical lineloss calculation is carried out on the equipment by adopting a root-mean-square current algorithm; by combining the real-time line loss obtained from the metering automation system, a loss model is constructed on the basis of the element loss, loss reduction and energy conservation analysis is carried out, auxiliary decisions can be provided for analog simulation technology loss reduction, marketing line loss analysis, power grid planning and loss reduction and energy conservation service, and the method and system have high practical application value.

Description

technical field [0001] The invention belongs to the technical field of power distribution, and in particular relates to a calculation and analysis method and system for comprehensive loss reduction and energy saving of power distribution lines and transformers. Background technique [0002] With the rapid development of the national economy, people's demand for power resources continues to rise, and the power load and grid capacity increase accordingly. will get higher and higher. [0003] At present, the power grid lines in many areas are not concentrated, and the distribution area is relatively wide, which has a direct impact on the increase of reactive power compensation costs. Furthermore, in the current power grid system, reactive power compensation has not been fully popularized, but at the same time, people are using more and more high-power electrical appliances, which will directly cause a significant increase in the inductive load of the power grid line. In turn,...
