Problems solved by technology

[0003] Although the measurement level of the distribution network is constantly improving, and there is already a large amount of measurement data in the local distribution network, from the perspective of the entire distribution network, the proportion of real-time monitoring data that can be observed is still small.
On the one hand, due to the situation of multiple data sources in some areas, some data is duplicated; on the other hand, there are missing cases in some areas

Abstract

The present invention is a practical calculation method for the effectiveness analysis of distribution network measurement based on multiple data sources. (2) Use quasi-real-time data for real-time measurement completion; (3) Steps for analyzing the effectiveness of distribution network switch measurement; its method integrates distribution network SCADA real-time data, distribution quasi-real-time information, typical load characteristics, etc. Data source, judge the validity of telemetry data, locate invalid signal objects, detect and identify bad switch measurements and switch states, so the state estimation of the distribution network can ensure the normal operation and management of the distribution network and ensure the normal operation of the distribution management system It is of great significance to exert its function.

Description

technical field [0001] The present invention relates to distribution network scheduling automation system technology, in particular to a distribution network scheduling advanced application numerical calculation, that is, a practical calculation method for distribution network measurement effectiveness analysis based on multiple data sources. Background technique [0002] The general idea of ​​distribution network status analysis is to first import the distribution network model of the production management system or GIS system into the distribution automation system through the message bus system, and import the main network model of the dispatching automation system into the distribution automation system. The automation system splices the main network model and the distribution network model to form an integrated main distribution network topologically connected model, and at the same time imports the distribution transformer current and power measurement of the power cons...
