Abstract

The invention discloses an on-site uninterruptible power supply automatic test method for an on-site feeder automation switch terminal, and relates to the technical field of distribution automation. The on-site uninterruptible power supply automatic test method for an on-site feeder automation switch terminal is suitable for on-site automatic test of on-site feeder automation equipment such as a voltage-time type, a voltage-current time type, a national grid adaptive type, a voltage-current time + relay protection type and a closing quick-break type. The on-site uninterruptible power supply automatic test method for an on-site feeder automation switch terminal uses a feeder automatic intelligent tester with a programmable function and a feeder condition switch adaptive simulator to complete the automatic test of the related functions and technical indicators of a power distribution switch terminal during the overall process of fault occurrence, fault judgment, fault isolation and non-faulty area power restoration for the fault occurrence position in various situations, such as the upstream, the downstream and irrelevant branches of the tested power distribution switch terminal under the transient fault and permanent fault conditions for one time when the tested switch device is running normally without power failure, at the same time, automatically generates a test report, andcan store, output or upload the test report to a cloud platform.

Description

technical field [0001] The invention relates to the technical field of power distribution automation, in particular to a method for fully automatic testing of on-site feeder automation switch terminals on site without power failure. Background technique [0002] The invention patent "Secondary Injection Test Method for Distribution Automation System" by Liu Jian and others of Shaanxi Electric Power Research Institute is to configure a distribution network fault simulation generator at each distribution automation terminal. The device is issued according to the test command computer The test plan simulates a fault in a certain section of the distribution network, and tests related links such as distribution terminals, communication systems, and master stations. The invention patent "Test Method for Synchronous Coordination of Primary Station Injection and Secondary Injection in Distribution Automation System" is mainly applicable to centralized distribution automation mode. ...
