Feeder automation action logic test method based on power distribution terminal service verification

Abstract

The invention provides a feeder automation action logic test method based on power distribution terminal service verification. Feeder automation action logic simulation verification in the normal operating states of terminals can be achieved by the adoption of terminal service verification simulating a transmitting mode. The method includes the following steps that firstly, through synchronous control of a master power distribution station, the multiple terminals on multiple feeders can simultaneously enter simulation state modes, fault simulation transmitting of the power distribution terminal on one feeder is synchronized, centralized feeder automation action logic is verified, and the problem that tests need to be synchronously added in a field is solved; master station and terminal simulation transmitting technical protocols are formulated, and the transmitting procedure that the terminals enter the simulation modes is formulated; thirdly, it is guaranteed that normal operation of the terminals is not affected by the simulation states of the terminals, and if a true fault occurs to a power distribution line in the simulation states of the terminals, actual fault information of the terminals can be transmitted to the master station in time and is not lost; the terminals in the simulation states simultaneously record the operating information of the power distribution line, and the operating information is called by the master station at any time.

Description

technical field [0001] The patent of the present invention relates to a logic test method for feeder automation based on power distribution terminal service verification. Background technique [0002] With the deepening of the application of distribution automation and the large-scale deployment of distribution automation terminals, the distribution network has higher and higher requirements for the reliability of feeder automation functions. The weak links in the construction and operation and maintenance of distribution automation are gradually discovered. The automated test method is complicated, and the normalized verification of multiple terminal action logics has become an area that urgently needs to be expanded. In terms of terminal information verification, at present, after the first transmission test is completed in various places, linkage tests are no longer performed; when the terminal has no change data for a long time, there is still no effective means to check...

AI Technical Summary

Problems solved by technology

[0003] At present, the verification of feeder automation action logic at home and abroad mainly adopts the "terminal injection method". To simulate a fault on a feeder, it is necessary to power off the distribution line, change the secondary wiring of multiple distribution terminals, and simulate multiple terminals on site. Adding a fault current for analog signaling requires high simultaneity for the terminal to simulate increased signaling. In addition, multiple simultaneous operations in different locations consume a lot of manpower and material resources.

[0004] In addition, the verification of feeder automation action logic at home and abroad mainly adopts "master station simulation software injection sending", that is, a set of software is installed in the master station, and the simulated terminal communicates with the master station to verify the feeder automation logic. Affect the online monitoring of the running terminal by the master station, the communication parameters of the master station need to be reconfigured, and the running state and communication state of the online terminal cannot be truly simulated
