A Field Test Method for Feeder Automation Fault Handling Logic

Abstract

The invention relates to a field test method for feeder automation fault handling logic, and its technical characteristics are: connecting a tester and a field distribution automation terminal together, and confirming the location of the wiring site at the same time; connecting the simulation software client to the distribution network , perform the simulation exit operation on the distribution automation terminal that has been connected to the tester, and at the same time call out the initialization section to wait for execution; make the initialization case in the tester the same as the initialization case execution time of the simulation software; after the test time is reached, the test After the execution of the initialization section is completed, the tester and simulation software automatically call out the next fault section for execution until the execution of this case is completed. The invention has a reasonable design, divides the entire network into multiple parts for subsection testing, greatly simplifies the testing workload without affecting the testing effect, and realizes the complete and efficient testing function for the complex power distribution network.

Description

technical field [0001] The invention belongs to the technical field of power distribution automation, in particular to a field test method for feeder automation fault processing logic.

Problems solved by technology

At present, the test of the distribution network automation terminal (FTU) mainly relies on the relay protection tester, and uses the method of simulating the voltage and current of the secondary side for testing. However, as the power grid system becomes larger and more complex , the traditional test method requires a large number of test instruments to test together, and it is difficult to achieve effective test of the line while consuming a lot of manpower and material resources
