FIELD: electricity. ^ SUBSTANCE: first intelligent electronic device (21) prepares an answer related to blocking, indicating condition of opening or blocking of the first switching device (111). A testing device (30) differing from the first intelligent electronic device (21) prepares a status of blocking, indicating condition of opening or blocking of the first switching device (111). The answer related to blocking is compared with the blocking status. At the same time the blocking status is identified by the testing device (30) on the basis of blocking rules and dynamic topology of a power substation produced on the basis of a standardised description of the static topology of a substation and the dynamic status of switching of the second switching devices (110a, 110b) of the power substation. ^ EFFECT: facilitation and expansion of a system level of testing of power substation automation systems blocking functions. ^ 6 cl, 2 dwg |
