Problems solved by technology

The traditional method relies on manually setting section data on site according to the one-line diagram, which can only be used for simple networks, and the speed is slow, the coordination is difficult, and batch operations cannot be performed
Moreover, it is difficult to effectively simulate the protection action time calculated in milliseconds, and it is difficult to truly reproduce the actual operation scene of the line

Abstract

The invention provides a site test method for feeder automation. The method comprises the following steps that definite value information about protection of an exit in a distribution network line is obtained first; the state of the line is divided into a plurality of cross section states in different sequences according to the feeder automation process, and information in the cross section states is set automatically according to the definite value information and a network topology state; the information of the cross section states is issued to test equipment according to the sequences; the test equipment controls output of electrical data automatically according to received information, and then testing is realized.

Description

technical field [0001] The invention relates to a distribution network of a power system, in particular to a field test method for feeder automation. Background technique [0002] Feeder automation refers to the automation of feeder lines between substation outlets and user electrical equipment. Its content can be summarized into two aspects: one is user detection, data measurement and operation optimization under normal conditions; the other is faults under accident conditions Detection, fault isolation, transfer and restoration of power control. [0003] When performing feeder automation on-site testing, it is necessary to determine the timing of changes in current, voltage, and switch status at each switch point for each test case in the distribution network to be tested. The traditional method relies on manually setting section data on site according to the one-line diagram, which can only be used for simple networks, and the speed is slow, the coordination is difficult...
