Problems solved by technology

Since the theoretical line loss is often only a reference for the actual line loss and cannot truly reflect the actual line loss, the traditional smart grid line loss detection method has the disadvantage of large detection error

Abstract

The invention discloses a smart power grid line loss detection method and system. The smart power grid line loss detection method includes the steps of obtaining monitoring data of a smart power grid, classifying monitoring values according to serial numbers of monitoring devices to obtain a plurality of monitoring sets, extracting the monitoring values within corresponding set time periods in the monitoring sets through a time coordination mechanism according to sampling time of the monitoring values, computing and outputting line loss values corresponding to the monitoring sets according to the monitoring values within the corresponding set time periods in the monitoring sets and a preset spatial-temporal model, enabling the lowest common multiples of sampling periods corresponding to all the monitoring values in the corresponding monitoring sets to serve as duration of the set time periods to extract the monitoring values, and synchronously computing the line losses through the extracted monitoring values within the same set time periods to guarantee the computing accuracy. The monitoring data of the smart power grid are obtained, coherent processing is carried out on the monitoring data, then the line losses are computed, the practical line loss condition can be truly reflected, and compared with a traditional smart power grid line loss detection method, the computing accuracy is improved, and the detection error is reduced.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a method and system for detecting line loss of smart grids. Background technique [0002] In the process of transmitting electric energy from the power plant to thousands of households, it needs to pass through multiple power transmission and transformation components. Since each electric component has losses, electric energy loss is inevitable. In addition, factors such as electromagnetic conversion, measurement errors and daily management will cause power loss. The loss of these electric energy is called line loss, which is an important technical index to measure the production technology level and management level of power supply enterprises. [0003] Smart grid refers to a fully automated power transmission network that can monitor and control each user and grid node, ensuring the two-way flow of information and power between all nodes in the entire transmission and dist...
