Feeder automation test system with automatic interference input function

Abstract

The invention discloses a feeder automation test system with an automatic interference input function. The feeder automation test system is connected with a power distribution network which comprises a power distribution terminal and a relay protector. The power distribution terminal and the relay protector respectively comprise a telemetering module, a remote signaling module and a remote control module. The feeder automation test system comprises a plurality of feeder automation testers and a console, wherein the feeder automation testers are respectively connected with the power distribution terminal or the relay protector, and the console is connected with all the feeder automation testers through a network system. The feeder automation test system is used for verifying the power distribution terminal deployed on site or the relay protector deployed on site and feeder automation processing logic of the power distribution terminal or the relay protector, whether a power distribution automation system which is deployed under the normal condition can process various faults correctly can be tested, the problem that fault coverage expansion is caused by the deployed power distribution automation system in the fault processing process under different interference conditions can be verified, and power supply reliability and power supply quality are greatly improved.

Description

technical field [0001] The invention relates to the field of feeder automation, in particular to a feeder automatic test system with automatic disturbance input. Background technique [0002] Feeder automation is mainly based on the fault signal collected by the distribution terminal installed on the distribution line, combined with the network topology of the distribution line and the operating status before the fault, automatically realizes the location and isolation of the faulty section, and restores the power supply in the non-faulty area. Feeder automation plays a very important role in improving the reliability and quality of power supply. [0003] However, feeder automation involves many links, namely, it is related to the operating characteristics of the primary system such as switches, and also involves various configuration parameters inside the power distribution terminal and various parameters of the decision-making center. The correctness of these parameters an...

Problems solved by technology

[0004] It is not only necessary to test whether these parameters meet the requirements of feeder automation under normal conditions, but also to test whether these parameters still meet the requirements of feeder automation when various input conditions are abnormal, and the current test method cannot meet these two requirements at the same time , which leads to the reduction of power supply reliability and power supply quality
