The PCS-9705 Bay Control Unit (abbreviated as BCU) is used
for bay level controlling and monitoring in substation, power
plant and industrial domain. It is suitable for an application
in Substation Automation System (abbreviated as SAS) with
distributed control IEDs.
The PCS-9705 can be applied into SAS via Ethernet network
in using different protocols. It can send/receive Generic Object
Oriented Substation Event (abbreviated as GOOSE) message
in a station level network
The PCS-9705 is designed for switchgear monitoring and
controlling. Also, it supports tap changer control for transformer
or shunt reactor. Additionally, closing synchronism check (25)
and auto-reclosing (79) are integrated.
The PCS-9705 can be used for both single and 1½ breaker
arrangements.
