Power distribution automation measurement completion method based on measurement data

Abstract

The invention discloses a power distribution automation measurement completion method based on measurement data, and belongs to the technical field of electric power engineering data processing. According to the method, according to a fracture surface file of distribution transform data in a measurement system, power distribution load current is calculated, a historical database of a power distribution automation system is updated, a distribution transform load feature curve is predicted according to the historical database updated by the power distribution automation system, the distributiontransform current load current is estimated according to the obtaining moment of the fracture surface file and the distribution transform load feature curve, the features of feeder electric equipmentare considered, the sum of all distribution transform current load currents within the current immeasurable feeder line critical measurement position power supply range serves as measurement data of the current immeasurable feeder line critical measurement position, through effective utilization of measurement data, data completion of feeder immeasurable key positions is achieved, the visible degree of the power distribution automation system is increased, and distribution network dispatching personnel conveniently know the running state of a power distribution network comprehensively.

Description

technical field [0001] The invention discloses a distribution automation measurement and completion method based on metering data, and belongs to the technical field particularly relating to power engineering data processing. Background technique [0002] With the continuous development of distribution automation, the requirements for distribution dispatching are increasing day by day, and the development of distribution dispatching is based on the fully observable distribution network. There are few real-time measurements in the distribution network, generally only in the feeder There are relatively complete measurements at the head end, and there are measurements on some feeder switches or feeder loads. Therefore, the measurement on the feeder is not sufficient. In , most of the loads in the distribution network are invisible to the distribution automation system. [0003] In the construction of the new generation of distribution automation system, the concept of "data sh...
