5 Management Function
PCS-9611 Feeder Relay
5-1
Date: 2014-04-08
5.1 Overview
The relay provides some management functions, such as protection sampling, metering, remote
control, signaling, event recording and fault & disturbance recording etc. All these functions can
ensure this relay meets the requirements of a modern power grid.
5.2 Measurement
This relay produces a variety of both directly and calculated power system quantities. Two kinds of
measurements are supported in this relay: protection sampling and metering. All these
measurands also can be transmitted to the SAS or RTU through communication. See Chapter 10
for more information about the communication and protocols.
5.2.1 Protection Sampling
This relay samples the protection related values with 24-point sampling rate per cycle. These
protection sampled values are being updated per 0.5s and can be viewed in the submenu
“
Measurement1
” of this relay or via relay communication. See
Section 8.2.3 for more details
about the protection measurands.
5.2.2 Metering
This relay samples the metering values with 48-point sampling rate per cycle. These metering
values are being undated per 0.5s
and can be viewed in the submenu “
Measurement2
” of this
relay or via relay communication. See Section 8.2.3 for more details about the metering values.
5.3 Circuit Breaker Control
This relay can receive the control commands to trip or close the circuit breaker. Up to 5 groups of
output relays in this relay can be configured as control outputs (closing and tripping). And only the
first closing output (local or remote) can be configured with synchronism check or dead check.
The control function includes local control and remote control. The local control command can be
gotten through the binary inputs or the submenu
“
Control
” (see
Section 8.2.8.4 ). The remote
control command can be from the substation automatic system through the communication.
Before executing a remote control command, it is necessary to put the control switch at the
“Remote” position to make the binary signal [Ctrl.Sig_EnCtrl] be “1”.
Each control output can be control with an interlock module (which can be configured through the
PCS-Explorer) if the corresponding interlock logic setting (see Section 7.4.3 ) is set as
“1”. If it
makes the control outputs without interlock control in such a situation, the binary signal
[Ctrl.Sig_Unblock] should be
“1”.
The remote control commands include remote tripping command, remote closing command etc.
See Chapter 10 for more information about the communication and protocols.
