The invention relates to an electrical network relay protection setting on-line verifying integrated data processing method. After an integrated verifying system formed by an EMS / DTS is started, the method performs processing according to the following steps: firstly, an electric network topology connection relation is obtained according to the section of the EMS; secondly, the network analysis parameters are initialized; thirdly, the verifying regulations are obtained; fourthly, the fault calculation is carried out; and finally, the setting verifying is finished. The invention performs on-line verifying to the electrical network relay protection setting, the protection range is extended, the mismatch ratio is reduced, and the time delay is short, therefore, the protective property is enhanced.
