1.2 Applications
The SIPROTEC
®
Bay Processing Unit 6MD665 is an integrated part of the SICAM
power automation system. Command outputs and indication inputs are especially
adapted to the requirements of high-voltage technology.
By means of appropriately equipped switchgears the Bay Processing Unit can com-
municate with the SICAM HV modules via a process bus. Therefore the system is also
called an intelligent switchgear bay. The SICAM HV modules are not suitable for all
types of switchgears. Detailed information can be obtained from your local Siemens
sales representative.
When connecting the circuit breaker, the Bay Processing Unit can check if the syn-
chronisation conditions of the two subnetworks to be combined are met (synchro-
check). This makes the use of an additional external synchronisation device unneces-
sary. The synchronisation conditions can be configured conveniently with the DIGSI
®
operating program. The device distinguishes between synchronous and asynchro-
nous networks and reacts differently on the connection.
Control functions The device provides a control function which can be accomplished for activating and
deactivating switchgears via integrated operator panel, system interface, binary
inputs, and the serial port using a personal computer with DIGSI
®
.
The status of the primary equipment can be transmitted to the device via auxiliary con-
tacts connected to binary inputs. The present status (or position) of the primary equip-
ment can be displayed on the device, and used for interlocking or plausibility monitor-
ing. The number of the operating equipment to be switched is limited by the binary
inputs and outputs available in the device or the binary inputs and outputs allocated
for the switch position indications. Depending on the primary equipment being con-
trolled, one binary input (single point indication) or two binary inputs (double point indi-
cation) may be used for this process.
The capability of switching primary equipment can be restricted by a setting associ-
ated with switching authority (Remote or Local), and by the operating mode (inter-
locked/non-interlocked, with or without password request).
Processing of interlocking conditions for switching (e.g. system interlocking) can be
established with the aid of integrated, user-configurable logic functions.
Messages and Mea-
sured Values The operating messages provide information about conditions in the power system
and the device. Measurement quantities and values that are calculated can be dis-
played locally and communicated via the serial interfaces.
Device indications can be assigned to a number of LEDs, externally processed via
output contacts, linked with user-definable logic functions and/or issued via serial
interfaces.
Communication For communication with external operator and control systems and Inter relay commu-
nication, serial interfaces are available.
A 9-pole DSUB socket on the front cover ensures the local communication with a per-
sonal computer. By means of the SIPROTEC
®
operating software DIGSI
®
4, all oper-
ational and evaluation tasks can be executed via this user interface, such as specify-
ing and modifying configuration parameters and settings, configuring user-specific
logic functions, retrieving operational messages and measured values, inquiring
device conditions and measured values, issuing control commands.
