Control logics for SBO/DIR modes
4.3.5
Control logics for 'HHD resetting and 'VAR resetting' are provided.
Receiving "Select command for HHD resetting" from the remote-end
(i)
Figure 4.3-9 shows the logic when a "Select command (Remote-RESET-Control)" signal is
applied in HHD control. The logic has an input-point "PWRQ_HHD_RSTREQ" for the
reception of the select command; the point should be mapped for the IEC61850 communication
(see sec. 4.3.8). The input-point "PWRQ_HHD_RSTREQ" is significant to HHD resetting; the
HHD failure will be indicated if mapping is not performed correctly.

Either "SBO mode" or "DIR mode"
(e.g., "ctlmodel" in IEC61850*)
‡Note: "Select condition" signal is provided from select condition scheme. For more
information, see Figure 4.3-10.
*Note: The PWRQTY function can run on either the "SBO mode" or the "DIR mode". The
user can use the signal "ctlmodel" in the IEC61850 communication.
Select condition for HHD resetting
