Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0027] Such as figure 1 As shown, a function simulation method of a relay protection device includes the following steps:

[0028] Step 1, receiving an excitation signal from a virtual tester; wherein, the excitation signal is a 0 / 1 sequence, a sine wave or a square wave;

[0029] Step 2, convert the incentive signal into incentive data, and send the incentive data to the database for storage; the database adopts SQLite3 database;

[0030] Step 3, in response to incentive data storage, obtain logic processing related data from the database, perform relay protection logic processing, and send the relay protection logic processing result to the database for storage;

[0031] Step 4, in response...
