Figure 9.1 Example AUTO Command Operation
The AUTO command example in Figure 9.1 shows that the relay supports
control from 3 circuit breakers and 16 remote bits through the SEL Fast
Operate protocol. You can access these by programming SEL
OGIC control
equations for Port 8 BR1–BR3 and RB1–RB16. You must enable Fast Operate
support in the relay port settings as well as the automatic message settings of
the SEL-2032. The SEL Fast Operate protocol does not require any additional
message settings to send Fast Operate messages to the relay. The SEL-2032
automatically composes and sends Fast Operate messages when the breaker
bits and remote bits change state within the SEL-2032.
Follow these steps to enable Fast Operate messages that set or clear remote
bits or breaker bits.
Step 1. Set the FASTOP setting equal to Y in the relay port settings for
the port connected to the SEL-2032. The relay breaker jumper
must be in the proper position to enable serial port commands.
Refer to the relay instruction manual for this setting.
Step 2. Enable Fast Operate messages in the SEL-2032 by setting the
auto-message setting SEND_OPER equal to Y.
Step 3. Toggle the corresponding Set and Clear elements SRB1–16,
CRB1–16, SBR1–4, and CBR1–4.
In the example above, control of breaker bit one, BR1, will send Fast Operate
OPEN or CLOSE commands for breaker one in the SEL-387E. Control of
breaker bit two, BR2, will send Fast Operate OPEN or CLOSE commands
for breaker two in the SEL-387E. In addition, control of breaker bit three,
BR3, will send Fast Operate OPEN or CLOSE commands for breaker three
in the SEL-387E. You should consult the SEL-387E instruction manual to
verify that, in the relay logic settings, the breaker control bits are assigned to
control appropriate outputs which in turn are used to energize the open or
close control circuits to the associated circuit breaker. Similarly, verify that, in
the SEL-2032 logic settings, remote bits are assigned to perform desired
controls.
Some relays, such as the SEL-421, do not have internal breaker bits, though
they can still control circuit breakers. When you set BR1 on a port connected
to an SEL-421, the SEL-2032 sends a message to the SEL-421 that asserts the
manual OPEN command bit OC1 for one processing interval. If you clear
BR1, the SEL-2032 sends a message to the SEL-421 that asserts the CLOSE
command bit CC1 for one processing interval. If you are using the default
settings, OC1 will open circuit breaker one and CC1 will close circuit breaker
one. You can control and condition the effect of OC1 and CC1 by changing
