The switch controller SCSWI initializes and supervises all
functions to properly select and operate switching primary
apparatuses. Each of the 10 switch controllers SCSWI may
handle and operate on one three-phase apparatus.
Each of the 3 circuit breaker controllers SXCBR provides
the actual position status and pass the commands to the
primary circuit breaker and supervises the switching
operation and positions.
Each of the 9 circuit switch controllers SXSWI provides the
actual position status and pass the commands to the
primary disconnectors and earthing switches and
supervises the switching operation and positions.
Interlocking
The interlocking function blocks the possibility to operate
primary switching devices, for instance when a disconnector
is under load, in order to prevent material damage and/or
accidental human injury.
Each apparatus control function has interlocking modules
included for different switchyard arrangements, where each
Hitachi Power Grids
function handles interlocking of one bay. The interlocking
function is distributed to each IED and is not dependent on
any central function. For the station-wide interlocking, the
IEDs communicate via the system-wide interbay bus (IEC
61850-8-1) or by using hard wired binary inputs/outputs.
The interlocking conditions depend on the circuit
configuration and apparatus position status at any given
time.
For easy and safe implementation of the interlocking
function, the IED is delivered with standardized and tested
software interlocking modules containing logic for the
interlocking conditions. The interlocking conditions can be
altered, to meet the customer's specific requirements, by
adding configurable logic by means of the graphical
configuration tool.
Switch controller SCSWI
The Switch controller (SCSWI) initializes and supervises all
functions to properly select and operate switching primary
apparatuses. The Switch controller may handle and operate
on one multi-phase device or up to three one-phase
devices.
Circuit breaker SXCBR
The purpose of Circuit breaker (SXCBR) is to provide the
actual status of positions and to perform the control
operations, that is, pass all the commands to primary
apparatuses in the form of circuit breakers via binary output
boards and to supervise the switching operation and
position.
Bay control QCBAY
The Bay control (QCBAY) function is used together with
Local remote and local remote control functions to handle
the selection of the operator place per bay. QCBAY also
provides blocking functions that can be distributed to
different apparatuses within the bay.
Proxy for signals from switching device via GOOSE
XLNPROXY
The proxy for signals from switching device via GOOSE
(XLNPROXY) gives an internal representation of the
position status and control response for a switch modelled
in a breaker IED. This representation is identical to that of
an SXCBR function.
GOOSE function block to receive a switching device
GOOSEXLNRCV
The GOOSE XLN Receive component is used to collect
information from another device's XCBR/XSWI logical node
sent over process bus via GOOSE. The GOOSE XLN
M13531-3 v4
Receive component includes 12 different outputs (and their
respective channel valid bits) with defined names to ease
the 61850 mapping of the GOOSE signals in the
configuration process.
