Embodiment Construction
[0031] The method for automatically verifying the protection function of the microcomputer-based main transformer differential protection device provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The present invention utilizes the hardware resources generally configured in the existing protection devices, does not need to add additional hardware, and adopts the method of adding an independent test program to realize function verification; its hardware cooperation logic is as follows: figure 1 shown; at the same time, it does not need the analog input of the external loop to simulate the fault, but uses the method of setting the simulated fault by the device software, such as figure 2 As shown; the accuracy verification of the sampling part of the device should be carried out by means of a protection tester and other methods. Without increasing hardware overhead and changing hardwa...
