Preface

Incorporated components, such as LEDs, transceivers, and laser emitters,
are NOT user serviceable. Return units to NR for repair or replacement.

Equipment components are SENSITIVE to electrostatic discharge (ESD).
Undetectable permanent damage can result if you do not use proper ESD
procedures. Ground yourself, your work surface, and this equipment
BEFORE removing any cover from this equipment. If your facility is not
equipped to work with these components, contact NR about returning this
device and related NR equipment for service.

Insufficiently rated insulation can deteriorate under abnormal operating
conditions and cause equipment damage. For external circuits, use wiring
of SUFFICIENTLY RATED insulation that will not break down under
abnormal operating conditions.

SEVERE power and ground problems can occur on the communications
ports of this equipment as a result of using non-standard cables. Please
use the wiring method recommended in the manual for communication
terminals.

DO NOT connect power to the relay until you have completed these
procedures and receive instruction to apply power. Equipment damage
can result otherwise.

Use of controls or adjustments, or performance of procedures other than
those specified herein, may RESULT IN hazardous radiation exposure.

The firmware may be upgraded to add new features or enhance/modify
existing features, please MAKE SURE that the version of this manual is
compatible with the product in your hand.

The PCS-9611S is widely adopted not only for conventional substations, but also for digital
substations. It supports IEC 61850 Editions 1 and 2 and provides GOOSE and SV network
interfaces with high real-time performance. The process level network supports peer-to-peer (P2P)
mode and networking mode, including single network mode and dual network mode. The station
level network can also receive and send MMS messages (such as interlocking signals) or process
level GOOSE messages (such as circuit breakers or disconnectors positions and trip signals).

1 Functions and Application

For the large-resistance grounding system, when an earth fault occurs, the zero-sequence current
sensitivity is insufficient, and the earth fault overcurrent protection may not operate. In this case,
sensitive earth fault protection (67/50/51SEF) can be configured.
For double busbars arrangement, the voltages of the two busbars can be connected to the
external voltage selection device firstly, and then the selected voltage is connected to the device;
the voltages of the two busbars can also be connected to the device directly and the voltage
selection function can be accomplished by the internal software.
In addition, the device provides some control functions such as synchronism check and
switchgear control etc., it also supports the measurement of apparent power (S), active power (P),
reactive power (Q), current (I), voltage (U), power factor (Cos), frequency (f) and others.

Figure 1.2-4 Single-star connection capacitor bank protection typical application

The application scenario corresponding to this configuration is neutral point ungrounded
single-star capacitor bank protection. The device provides phase overcurrent protection (50/51P),
earth fault overcurrent protection (50/51G), undervoltage protection (27P), phase overvoltage
protection (59P), undercurrent protection (37), voltage unbalance protection (60/59), breaker
failure protection (50BF) and other protection functions.
In addition, the device provides the switchgear control function, it also supports the measurement
of apparent power (S), active power (P), reactive power (Q), current (I), voltage (U), power factor
(Cos), frequency (f) and others.
