Power-distribution-network measurement effectiveness analysis practical calculation method based on multiple data sources

Abstract

The invention provides a power-distribution-network measurement effectiveness analysis practical calculation method based on multiple data sources. The method comprises the following steps that firstly, quasi-real-time data are corrected and analyzed statically, and non-real-time measurement data collected by other systems are verified and analyzed reasonably; secondly, real-time measurement complementing is conducted on the quasi-real-time data; thirdly, the measurement effectiveness of switches of a distribution network is analyzed. According to the method, the multiple data sources such as distribution network SCADA real-time data, distribution transformer quasi-real-time information and typical load characteristics are integrated for judging the effectiveness of telemetry data, positioning ineffective signal objects and detecting and identifying measurement of bad switches and the states of the switches, therefore, estimation of the state of the power distribution network has great significance to normal operation and management of the power distribution network and a guarantee that a power distribution management system gives play to the functions of the power distribution management system normally.

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...

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
