Embodiment Construction

[0025] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0026] Before elaborating the present invention, it should be noted that in order to solve the compatibility and interoperability problems between different information and communication protocols in the power grid, the International Electrotechnical Commission has proposed a number of standards and specifications, among which IEC61968-301 (CIM) The standard and IEC61850 are generally recognized by the industry. The former is aimed at the data interaction of power control centers such as SCADA (data acquisition and monitoring control system), EMS (energy management system), and DMS (distribution network management system), while the latter is aimed at Interoperability issues in the field of s...

Abstract

A multi-source data fusion method for a wide-area measurement control system of a power distribution network relates to the technical field of data fusion of the power distribution network, and comprises the following three steps: 1, storing multi-source data into different data sets in a classified manner; 2, preprocessing all the data; and 3, unifying standards and types of all the data, and realizing interaction among the data in a unified language form. The multi-source data fusion method for the wide-area measurement control system of the power distribution network can effectively realizeinteraction, association and fusion among multi-source data of the power distribution network.

Description

technical field [0001] The invention relates to the technical field of distribution network data fusion, in particular to a multi-source data fusion method for a distribution network wide-area measurement control system. Background technique [0002] "Data Fusion" is a multi-level, multi-faceted process that includes the detection, correlation, estimation, and synthesis of data from multiple sources to obtain accurate status and identity estimates as well as complete and timely battlefield situation and threat estimates. [0003] With the construction of smart grid, more and more measurement terminals or systems are arranged in the distribution network, such as distribution network micro-synchrophasor measurement unit (D-PMU), advanced measurement system (AMI), these devices are different from traditional The distribution network SCADA system together constitutes a new distribution network hybrid measurement and control system. On the other hand, due to the widespread acces...
