GOOSE receiving block (GOSUBBLK)
This function is used for receiving or rejecting GOOSE subscription
information from another IED in Test mode. This function is used for testing
in case of bad reception (For example, Validation of Interlock determination).
The user can simulate a bad reception condition passively by using two
GOOSE Sending Blocks.
Note: The user may perform bad reception tests from a remote terminal using the
GOSNDBLK function. However, carrying out the GOSNDBLK function at a
remote terminal may influence the overall operation of other IEDs, because
communication packets will not be received from the remote terminal. In order to
avoid that the user can simulate bad reception tests for a particular IED using the
GOSUBBLK function. As a result, testing will only affect the particular IED
under test i.e. all other terminals will not be influenced by the tests.
Function test screen: Function test screen is provided for testing; the use can
program test operations, which can be implemented in protection and control
functions. Figure 12.8-4 exemplifies the Test screen. Automatic supervision
will stop when the user sets Off for A.M.F (for more information about the
automatic supervision, see
Figure 12.8-4 Function test menu (an example)
Binary input test screen: The user can have a virtual signal to a binary input
circuit using the binary input test screen. Figure 12.8-5 shows an example;
the user can select IO#1 or IO#3. (Actually, the content displayed will differ
depending upon the binary IO module inserted. Refer to Chapter
