Problems solved by technology
However, due to too many lines in the distribution network, the point-by-point test method requires a lot of manpower
Therefore, the actual situation is that many distribution lines are directly put into use without completing the calibration work, resulting in many potential risk factors in the system

The invention discloses a full-automatic simulation test method and system for a feeder line self-healing master station. The method comprises the steps of simulating a self-healing starting condition and a fault signal through a feeder line self-healing simulation system, transmitting the self-healing starting condition and the fault signal to a feeder line self-healing system, enabling the feeder line self-healing system to start a fault positioning function according to the self-healing starting condition, and comparing the fault signal with a set fault point to generate a test result of fault positioning; and according to the test result, providing a judgment result and a strategy for power supply recovery of a fault isolation area and a non-fault area through a UI interface. Through the feeder line self-healing simulation system, a function that a tester at the secondary equipment side needs to carry out operation and control on the secondary injection equipment is transferred to a core tester at the main station side to replace the original tester at the secondary equipment side, so that the core tester at the main station side can more thoroughly master a power distribution automation process, and the fault processing function success rate, the feeder line self-healing commissioning rate and the distribution automation test efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of power distribution automation testing, in particular to a fully automatic simulation testing method and system for a feeder self-healing master station. Background technique [0002] The test of the distribution automation system requires the cooperation of the core testers on the main station side and the testers on the secondary equipment side. In the existing test method, the testers on the secondary equipment side are responsible for injecting voltage and current analog quantities and input and output signal quantities into the secondary equipment (DTU / FTU / TTU) through the secondary injection equipment and the analog switch unit. According to the different dimensions injected by the secondary equipment, the testers check the processing performance and system strategy of the main station on the main station side, and confirm the test results of power distribution automation. [0003] Although my count...
