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

Embodiment Construction

[0021] The present invention will be further described below in conjunction with examples.

[0022] The feeder automated testing method with automatic disturbance input will now be described in detail according to an exemplary embodiment of the present invention, comprising the following steps:

[0023] Communicate and connect multiple feeder automatic testers with the power distribution terminal or relay protection of the power distribution network to be tested;

[0024] Model the distribution network to be tested through the console, establish and execute test cases; among them, the distribution network model established by the distribution network fault simulation software can be any distribution network model, such as the hand-in-hand ring network distribution network, Multi-power open-loop network, dual-power closed-loop network;

[0025] The console loads the initialization data of the test case, simulates the initialization state of the power distribution network, and ...

Abstract

The invention discloses a feeder automation test method with an automatic interference input function. The method includes the following steps that testers are connected with a power distribution terminal or a relay protector, the testers and a console are connected with a network, the console loads test cases, simulated data of monitoring points are obtained and transmitted to all the testers through the network, the testers control output modules themselves to output electric data, receive remote control signals sent out by the power distribution terminal or the relay protector in real time and transmit the remote control signals to the console, the console determines reactions to the remote control signals according to configurations of the test cases, the simulated data are changed through the testers, and whether the tested power distribution terminal or the relay protector and feeder automation processing logic of the tested power distribution terminal or the relay protector are correct is judged. Thus, parameters and failure processing logic of a feeder automation system are tested through electric reactions of feeders suffering from failures on a simulated power distribution network, 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 method 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...
